To specify technical scheme of the present invention through specific embodiment below.

The flow chart of the communication means that Figure 1A provides for first embodiment of the invention.Shown in Figure 1A, the method for present embodiment comprises:

Step 101, Macro are that a UE carries out the ascending resource configuration, so that a UE sends upward signal or channel to a grand station and a PLN respectively according to said ascending resource configuration.

In the present embodiment, be that example describes with the LPN (i.e. a LPN) of a UE in the network (i.e. a UE) and the potential access of this UE (potential access can be to have inserted maybe to insert), other UE select the process of point of network attachment identical therewith.In various embodiments of the present invention, said network is meant the network that is made up of Macro and Macro control each LPN down, and each LPN passes through the wired or wireless mode of optical fiber or other and is connected each LPN of Macro centralized control with Macro.The coverage of each LPN and Macro has at least part to repeat.Wherein, a UE is also under the covering of Macro.

Macro is that a UE carries out the ascending resource configuration, and Macro is through ascending resource configuration indication the one UE transmission which or which upward signal or up channel, and corresponding running time-frequency resource position.In the present embodiment, Macro through ascending resource configuration indication the one UE to Macro or/and a LPN sends upward signal or up channel.Wherein, Macro can indicate a UE to send wherein any one or combination in any such as PUSCH, PUCCH, PRACH, DMRS and SRS, but is not limited thereto.

The one UE receives Macro or/and after the ascending resource configuration that a LPN sends, according to the indication of ascending resource configuration to Macro or/and a LPN sends upward signal or up channel.

Step 102, Macro measure upward signal or channel that a UE sends, obtain the first out-hole run information of Macro itself, and a LPN measures upward signal or channel that a UE sends, obtains the first out-hole run information of a LPN.

Wherein, the first out-hole run information is meant the out-hole run information that upward signal that a UE is sent or channel measure.The first out-hole run information of Macro is meant the out-hole run information that the upward signal that the one UE sent by Macro or channel measure; The first out-hole run information of the one LPN is meant the out-hole run information that the upward signal that the one UE sent by a LPN or channel measure.

Step 103, Macro receive the first out-hole run information of a LPN of LPN transmission.

In the present embodiment, after a LPN measures the first out-hole run information of a LPN, the first out-hole run information of a LPN is sent to Macro; Macro receives the first out-hole run information of a LPN of LPN transmission.

Step 104, Macro to Macro's and/or the first out-hole run information of a LPN carry out bias treatment, obtain the bias treatment result.

In the present embodiment, Macro can add a bias on the first out-hole run information of Macro, and/or on the first out-hole run information of a LPN, adds a bias.Wherein, added bias can be on the occasion of, also can be negative value.The first out-hole run information of Macro after the result of bias treatment can make a the LPN first out-hole run information after the biasing greater than biasing as far as possible is so that a UE can select a LPN as its point of network attachment.Can will be appreciated that the size and positive and negative can the setting as required of the bias of increase.If desired with UE as much as possible attached to grand station, the first out-hole run information of the Macro after also can making a the LPN first out-hole run information after the biasing less than biasing, the present invention does not specify this.

A kind of execution mode comprises: Macro is last can to store the bias tabulation in advance, in this bias tabulation, stores Macro and carries out the required relevant information of bias treatment.In the present embodiment, store in the bias tabulation in the first out-hole run information of Macro during, be left intact or increase the information of 0 bias less than the first out-hole run information of a LPN.In addition, in the bias tabulation, also store following any one information:

During more than or equal to the first out-hole run information of a LPN, need increase by the first up bias in the first out-hole run information of Macro to the first out-hole run information of Macro.Wherein, the first up bias is a negative value, is mainly used in the first out-hole run information of Macro is turned down.

During more than or equal to the first out-hole run information of a LPN, need increase by the second up bias in the first out-hole run information of Macro to the first out-hole run information of a LPN.Wherein, the second up bias be on the occasion of, be mainly used in the first out-hole run information of a LPN heightened.

In the first out-hole run information of Macro during, need increase by the first up bias to the first out-hole run information of Macro and the first out-hole run information of a LPN is increased by the second up bias more than or equal to the first out-hole run information of a LPN.

Based on above-mentioned, Macro can carry out bias treatment to the first out-hole run information according to preset bias tabulation, and the concrete mode of handling comprises:

If the first out-hole run information of Macro is less than the first out-hole run information of a LPN, then Macro can not handle the first out-hole run information of Macro, the first out-hole run information of a LPN is not carried out bias treatment yet.In other words, Macro with Macro's and/or the first out-hole run information of a LPN increase bias, but this bias is 0.

If the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN, arbitrary bias treatment mode below then Macro can adopt:

Macro is according to " in the first out-hole run information of Macro during more than or equal to the first out-hole run information of a LPN; need increase by the first up bias to the first out-hole run information of Macro " this information of storage in the bias tabulation; The first out-hole run information of Macro itself is increased by the first up bias; Keep the first out-hole run information of a LPN constant, make the first out-hole run information of the Macro after setovering and the first out-hole run information of a LPN compare.The first out-hole run information of supposing Macro is x1; The first up bias is a1, and the first out-hole run information of a LPN is y1, and then the first out-hole run information of the Macro after the biasing is (x1+a1); Then when (x1+a1)＜y1, select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.

Macro is according to " in the first out-hole run information of Macro during more than or equal to the first out-hole run information of a LPN; need increase by the second up bias to the first out-hole run information of a LPN " this information of storage in the bias tabulation; The first out-hole run information of the one LPN is increased by the second up bias; Keep the first out-hole run information of Macro constant, make the first out-hole run information of Macro and the first out-hole run information of the LPN after the biasing compare.The first out-hole run information of supposing Macro is x1; The first out-hole run information of the one LPN is y1, and the second up bias is a2, and then the first out-hole run information of the LPN after the biasing is (y1+a2); Then when x1＜(y1+a2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.

Macro is according to " in the first out-hole run information of Macro during more than or equal to the first out-hole run information of a LPN; need increase by the first up bias to the first out-hole run information of Macro and the first out-hole run information of a LPN is increased by the second up bias " this information of storage in the bias tabulation; The first out-hole run information of Macro is increased by the first up bias; The first out-hole run information of the one LPN is increased by the second up bias, make the first out-hole run information of the Macro after setovering and the first out-hole run value of the LPN after the biasing compare.When (x1+a1)＜(y1+a2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.

In this explanation, Macro also can not tabulate according to bias the first out-hole run information is carried out bias treatment, and directly carries out bias treatment according to the comparative result with first an out-hole run information LPN Macro.

Step 105, Macro select a LPN or the Macro point of network attachment as a UE according to the bias treatment result, so that a UE communicates through point of network attachment.

Macro to Macro itself carry out bias treatment with first an out-hole run information LPN after; If the first out-hole run information of Macro is less than the first out-hole run information of a LPN; The service that the one LPN is described is better than Macro; So Macro is that a UE selects a LPN as its point of network attachment, thereby a UE is communicated through a LPN.If the first out-hole run information of Macro greater than the first out-hole run information of a LPN, explains that the service of Macro is better than a LPN,, thereby a UE is communicated through Macro so Macro selects the point of network attachment of Macro as a UE.

In the present embodiment; Point of network attachment when Macro selects a LPN as up receive of a UE; Be used for being responsible for receiving upward signal or the channel that a UE sends; Point of network attachment when selecting a LPN as descending send of a UE simultaneously is used for being responsible for sending downstream signal or channel to a UE.Perhaps, the point of network attachment when point of network attachment when Macro selects Macro simultaneously as up reception of a UE and descending transmission of a UE is responsible for receiving upward signal or the channel that a UE sends and is responsible for sending downstream signal or channel to a UE.

In the present embodiment,, and, make UE can select LPN, solved prior art and can't improve from the sub-district of LPN or the problem of regional split gain as point of network attachment through out-hole run information is carried out bias treatment through use out-hole run information.In addition, present embodiment does not receive the restriction of identical cell ID scene and different cell ID scenes, under any scene, all can make more UE select LPN as point of network attachment, has improved sub-district or regional split gain from LPN.

The flow chart of the communication means that Figure 1B provides for second embodiment of the invention.Shown in Figure 1B, the method for present embodiment comprises:

Step 111, Macro are that a Macro itself and a LPN carry out the downstream signal configuration; So that a UE according to said downstream signal configuration respectively the downstream signal with a LPN of Macro is measured, with the first down-run survey information of obtaining Macro and the first down-run survey information of a LPN.

In the present embodiment, be that example describes with the LPN (i.e. a LPN) of a UE in the network (i.e. a UE) and the potential access of this UE, other UE select the process of point of network attachment identical therewith.Description about network can be repeated no more at this referring to the description of step 101.

Macro is that a UE carries out downstream signal configuration, and Macro receives and measure which or which downstream signal through downstream signal configuration indication the one UE, and indicates a UE that measurement result is returned.In the present embodiment, Macro measures the downstream signal of Macro and LPN transmission through downstream signal configuration indication the one UE.Wherein, Macro can indicate a UE that CSI-RS or USRS are measured, and measurement result is returned to a Macro and a LPN, but is not limited thereto.

After the one UE receives the downstream signal configuration of Macro or LPN transmission, respectively the downstream signal of Macro and/or LPN transmission is measured according to the indication of downstream signal configuration, and measurement result is returned to a Macro and/or a LPN.Wherein, a UE measures the first down-run survey information of Macro to the downstream signal of Macro, and a UE measures the first down-run survey information of a LPN to the downstream signal of a LPN.

Step 112, Macro receive the first down-run survey information of the Macro of UE transmission, and a LPN receives the first down-run survey information of a LPN of UE transmission.

Wherein, after a UE measures the first down-run survey information of Macro, the first down-run survey information of Macro is sent to Macro.After the one UE measures the first down-run survey information of a LPN, the first down-run survey information of a LPN is sent to a LPN.

Step 113, Macro receive the first down-run survey information of a LPN of LPN transmission.

The one LPN receives after a UE sends to its first down-run survey information, and its first down-run survey information is sent to Macro, and Macro receives the first down-run survey information of the LPN that a LPN sends.

In this explanation, present embodiment is that example describes with the first down-run survey information that a LPN and Macro receive separately separately, but is not limited to this.For example, a LPN can assist Macro to receive the first down-run survey information of the Macro of UE feedback, and the first down-run survey information that will receive Macro sends to Macro.Again for example, Macro can also assist a LPN to receive the first down-run survey information of a LPN of UE feedback.

Step 114, Macro to Macro's and/or the first down-run survey information of a LPN carry out bias treatment, obtain the bias treatment result.

In the present embodiment, Macro can add a bias on the first down-run survey information of Macro, and/or on the first down-run survey information of a LPN, adds a bias.Wherein, added bias can be on the occasion of, also can be negative value.The first down-run survey information of Macro after the result of bias treatment should make a the LPN first down-run survey information after the biasing greater than biasing as far as possible is so that a UE can select a LPN as its point of network attachment.

A kind of execution mode comprises: Macro is last can to store the bias tabulation in advance, in this bias tabulation, stores Macro and carries out the required relevant information of bias treatment.In the present embodiment, store in the bias tabulation in the first down-run survey information of Macro during, be left intact or increase the information of 0 bias less than the first down-run survey information of a LPN.In addition, in the bias tabulation, also store following any one information:

During more than or equal to the first down-run survey information of a LPN, need increase by the first descending bias in the first down-run survey information of Macro to the first down-run survey information of Macro.Wherein, the first descending bias is a negative value, is mainly used in the first down-run survey information of Macro is turned down.

During more than or equal to the first down-run survey information of a LPN, need increase by the second descending bias in the first down-run survey information of Macro to the first down-run survey information of a LPN.Wherein, the second descending bias be on the occasion of, be mainly used in the first down-run survey information of a LPN heightened.

In the first down-run survey information of Macro during, need increase by the first descending bias to the first down-run survey information of Macro and the first down-run survey information of a LPN is increased by the second descending bias more than or equal to the first down-run survey information of a LPN.

Based on above-mentioned, Macro can carry out bias treatment to the first down-run survey information according to preset bias tabulation, and the concrete mode of handling comprises:

If the first down-run survey information of Macro is less than the first down-run survey information of a LPN, then Macro can not handle the first down-run survey information of Macro, the first down-run survey information of a LPN is not carried out bias treatment yet.In other words, Macro with Macro's and/or the first down-run survey information of a LPN increase bias, but this bias is 0.

If the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN, arbitrary bias treatment mode below then Macro can adopt:

Macro is according to " in the first down-run survey information of Macro during more than or equal to the first down-run survey information of a LPN; need increase by the first descending bias to the first down-run survey information of Macro " this information of storage in the bias tabulation; The first down-run survey information of Macro itself is increased by the first descending bias; Keep the first down-run survey information of a LPN constant, make the first down-run survey information of the Macro after setovering and the first down-run survey information of a LPN compare.The first down-run survey information of supposing Macro is x2; The first descending bias is b1, and the first down-run survey information of a LPN is y2, and then the first down-run survey information of the Macro after the biasing is (x2+b1); Then when (x2+b1)＜y2, select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.

Macro is according to " in the first down-run survey information of Macro during more than or equal to the first down-run survey information of a LPN; need increase by the second descending bias to the first down-run survey information of a LPN " this information of storage in the bias tabulation; The first down-run survey information of the one LPN is increased by the second descending bias; Keep the first down-run survey information of Macro constant, make the first down-run survey information of Macro and the first down-run survey information of the LPN after the biasing compare.The first down-run survey information of supposing Macro is x2; The first down-run survey information of the one LPN is y2, and the second descending bias is b2, and then the first down-run survey information of the LPN after the biasing is (y2+b2); Then when x2＜(y2+b2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.

Macro is according to " in the first down-run survey information of Macro during more than or equal to the first down-run survey information of a LPN; need increase by the first descending bias to the first down-run survey information of Macro and the first down-run survey information of a LPN is increased by the second descending bias " this information of storage in the bias tabulation; The first down-run survey information of Macro is increased by the first descending bias; The first down-run survey information of the one LPN is increased by the second descending bias, make the first down-run survey information of the Macro after setovering and the first down-run survey value of the LPN after the biasing compare.When (x2+b1)＜(y2+b2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.

In this explanation, Macro also can not tabulate according to bias the first down-run survey information is carried out bias treatment, and directly carries out bias treatment according to the comparative result with first a down-run survey information LPN Macro.

Step 124, Macro to Macro's and/or the first out-hole run information of a LPN and Macro's and/or a LPN's the first down-run survey information carry out bias treatment respectively, obtain the bias treatment result.

In the present embodiment; Macro can add a bias on the first down-run survey information of Macro; And/or on the first down-run survey information of a LPN, add a bias; And/or on the first out-hole run information of Macro, add a bias, and/or on the first out-hole run information of a LPN, add a bias.Wherein, added bias can be on the occasion of, also can be negative value.The result of bias treatment should make a UE can select a LPN as its point of network attachment as far as possible.

A kind of execution mode comprises: Macro is last can to store the bias tabulation in advance, in this bias tabulation, stores Macro and carries out the required relevant information of bias treatment.In the present embodiment, be that a UE selects its point of network attachment according to the first out-hole run information and the first down-run survey information simultaneously.In order to select a LPN as its point of network attachment for a UE; Store in the first out-hole run information of Macro during in the tabulation of the bias of present embodiment less than the first out-hole run information of a LPN; Be left intact or increase the information of 0 bias; With in the first down-run survey information of Macro during less than the first down-run survey information of a LPN, be left intact or increase the information of 0 bias.

In addition; In bias tabulation, also store in the following information any one, the first out-hole run information that perhaps can guarantee Macro after the bias treatment less than the first out-hole run information of a LPN and/or bias treatment after the first down-run survey information of Macro less than the various combinations of the following information of the first down-run survey information of a LPN:

Based on above-mentioned, Macro can carry out bias treatment to the first out-hole run information or the first down-run survey information according to preset bias tabulation, and the concrete mode of handling comprises:

If the first out-hole run information of Macro less than the first down-run survey information of the first out-hole run information of a LPN and Macro less than the first down-run survey information of a LPN any one situation wherein; Then Macro can be left intact, but is not limited thereto.For example; If the first out-hole run information of Macro is less than the first out-hole run information of a LPN; But the first down-run survey information of Macro itself is more than or equal to the first down-run survey information of a LPN; Then Macro can only carry out bias treatment to Macro with first a down-run survey information LPN, and concrete bias treatment mode can be referring to the description of step 114.

Wherein, Macro is that a UE selects the detailed execution mode of point of network attachment can be referring to the corresponding description in step 104, step 114 and the step 124 under above-mentioned various adjusted bias treatment results.

Present embodiment is through according to Macro and a load LPN, or Macro with a resource occupation rate LPN the bias treatment result adjusted, and has the beneficial effect of load balancing flexibly.

In practical application, Macro can select point of network attachment for each UE through the method in the foregoing description.UE selects will or communicate through point of network attachment with point of network attachment after the point of network attachment.In network, exist under the situation of a plurality of LPN, will have mutual interference mutually between each LPN and LPN and the Macro.For reduce between each LPN and LPN and Macro between mutual interference mutually, improve communication quality, the embodiment of the invention provides a kind of distribution method of time frequency resources to solve the problems referred to above.The distribution method of time frequency resources that the embodiment of the invention provides mainly be between the stronger LPN of potential interference or LPN and Macro distribute orthogonal time frequency resources, make between the LPN or LPN communicates with Macro use orthogonal time frequency resources and its UE.

Fig. 2 A is the flow chart of a kind of resource allocation methods of providing of fourth embodiment of the invention.Shown in Fig. 2 A, the method for present embodiment comprises:

Step 201, Macro obtain the interference value between per two LPN in the network.

In the present embodiment, Macro can be divided into high interference or low the interference with the interference strength between the LPN in twos.Concrete, Macro passes through interference threshold as dividing high interference and the low thresholding that disturbs.Based on this, Macro can characterize the interference strength between the LPN in twos through interference value.

Wherein, Macro can obtain each LPN in the network with disturb relevant information, and comparing with disturbing relevant information between the LPN in twos obtained the interference value between the LPN in twos according to what obtain with the relevant information of interference.

Present embodiment provides several kinds of Macro to obtain the execution mode of the interference value between per two LPN.

A kind of execution mode comprises shown in Fig. 2 B:

Step 2011a, Macro obtain the second out-hole run information of each LPN in the network, and the said second out-hole run information is that each LPN measures upward signal or the channel that network side (being Macro) disposes a UE transmission of its measurement in the network.

Wherein, Macro can select a UE, disposes the upward signal or the channel of this UE transmission and measures, and obtains the second out-hole run information of Macro.Each LPN in the network also can be according to this UE of selection of configuration of network side, and upward signal or channel that this UE sends are measured, and obtains the second out-hole run information of oneself.The second out-hole run information and the first out-hole run information in the present embodiment are similar; If Macro and the UE that each LPN selects are a UE; And upward signal that is sent or channel are also identical; Then for the LPN among each LPN, the second out-hole run information is exactly the first out-hole run information.

After each LPN measures the second out-hole run information separately, separately the second out-hole run information is sent to Macro.Macro receives the second out-hole run information of each LPN oneself of each LPN transmission.

Step 2012a, Macro in the network in twos the difference of the second out-hole run information of LPN and up difference threshold compare, judge whether the difference of the second out-hole run information of two LPN that compare is less than or equal to up difference threshold; If judged result is for being execution in step 2013a; If judged result is for denying execution in step 2014a.

Wherein, up difference threshold is predefined, and its size is decided by concrete network environment, and its occurrence is not done qualification.

Interference value between two LPN that step 2013a, Macro confirm to compare is first interference value.

Wherein, it is high interference that first interference value shows between two LPN, or is potential high interference.

Interference value is second interference value between two LPN that step 2014a, Macro confirm to compare.

Wherein, second interference value shows between two LPN to be low the interference, or is potential low interference.

Another kind of execution mode comprises shown in Fig. 2 C:

Step 2011b, Macro obtain the second down-run survey information of each LPN in the network, and the said second down-run survey information is that a pre-configured UE of network side (being Macro) measures the downstream signal that each LPN sends.

Wherein, Macro can measure through UE reception downstream signal of downstream signal configuration indication and to downstream signal, and reporting measurement result, the i.e. second down-run survey information of Macro.Each LPN in the network also can be according to this UE of selection of configuration of network side, and sends downstream signal to this UE.Before this, Macro receives the downstream signal of LPN through this UE of downstream signal configuration indication and downstream signal is measured, and the reporting measurement result, and the second down-run survey information reporting that is about to LPN is given LPN.The second down-run survey information and the first down-run survey information in the present embodiment are similar; If Macro and the UE that each LPN selects are a UE; And the downstream signal that is sent is also identical, and then for the LPN among each LPN, the second down-run survey information is exactly the first down-run survey information.

After each LPN receives the second down-run survey information that UE reports, separately the second down-run survey information is sent to Macro.Macro receives the second down-run survey information of each LPN oneself of each LPN transmission.

Step 2012b, Macro in the network in twos the difference of the second down-run survey information of LPN and descending difference threshold compare, judge whether the difference of the second down-run survey information of two LPN that compare is less than or equal to descending difference threshold; If judged result is for being execution in step 2013b; If judged result is for denying execution in step 2014b.

Wherein, descending difference threshold is predefined, and its size is decided by concrete network environment, and its occurrence is not done qualification.

Interference value between two LPN that step 2013b, Macro confirm to compare is first interference value.

Interference value between two LPN that step 2014b, Macro confirm to compare is second interference value.

Another execution mode comprises shown in Fig. 2 D:

Step 2011c, Macro obtain the positional information of each LPN in the network.

Wherein, the positional information of LPN is meant the residing geographical position of LPN.

Step 2012c, Macro obtain the distance between the LPN in twos, and judge whether the distance between the LPN is less than or equal to distance threshold in twos according to the positional information of LPN in twos in the network; If judged result is for being execution in step 2013c; If judged result is for denying execution in step 2014c.

Wherein, distance threshold is predefined, and its size is decided by concrete network environment, and its occurrence is not done qualification.

Distance between the LPN is meant according to two LPN address locations of living in twos, and two LPN that obtain are in geographic distance.Wherein, two LPN have embodied the relation between the coverage of two LPN to a certain extent in geographic distance.

Interference value between two LPN that step 2013c, Macro confirm to compare is first interference value.

Interference value between two LPN that step 2014c, Macro confirm to compare is second interference value.

Wherein, second interference value shows between two LPN to be low the interference, or is potential low interference.Step 202, Macro, are divided into the LPN in the network in one or more interference groups greater than the rule that two LPN of preset interference threshold are divided in different interference groups according to interference value.

Behind the interference relationships in determining network between each LPN, Macro is the rule that two LPN of high interference are divided in different interference groups according to interference relationships, and each LPN in the network is divided into groups.Wherein, the possibility of result of grouping comprises an interference group or a plurality of interference group.

Obtain the execution mode of the interference value between the LPN in twos in conjunction with above-mentioned Macro; Macro can be with interference value between the LPN and preset interference threshold compare in twos; Between two LPN of interference value greater than interference threshold is high interference, need be divided in the different interference groups.In the present embodiment, interference threshold less than first interference value greater than second interference value.

Step 203, Macro are that a LPN distributes running time-frequency resource, so that the running time-frequency resource that a LPN passes through to be distributed is communicated by letter with a UE according to the rule of distributing the quadrature running time-frequency resource between difference interference group.

Fig. 2 E is the flow chart of the another kind of resource allocation methods that provides of fourth embodiment of the invention.Shown in Fig. 2 E, the method for present embodiment comprises:

Step 201a, Macro obtain the interference value between per two LPN in the network.

Step 201a can repeat no more at this referring to the description of step 201.

Step 202a, Macro are divided in same interference group according to two LPN that interference value is less than or equal to interference threshold, and interference value is divided into the LPN in the network in one or more interference groups greater than the rule that two LPN of interference threshold are divided in different interference groups.

In the present embodiment, the Macro while is divided in same interference group according to two LPN that interference value is less than or equal to interference threshold, and interference value carries out packet transaction greater than the rule that two LPN of interference threshold are divided in different interference groups to the LPN in the network.

Step 203a, Macro are divided into Macro itself in another interference group that is different from above-mentioned one or more interference groups, perhaps Macro itself are divided in the interference group in above-mentioned one or more interference group.

After each LPN was divided into groups, Macro also divided into groups to himself.

A kind of execution mode that Macro divides into groups to himself is: Macro this means that directly with oneself being divided in the independently interference group between Macro and all LPN be strong jamming.

The another kind of execution mode that Macro divides into groups to himself is: Macro is according to the interference value between each LPN in Macro oneself and the network; The LPN and the Macro that are less than or equal to interference threshold according to interference value are divided in same interference group; Interference value is divided in different interference groups greater than the LPN of interference threshold with Macro, and oneself is divided into groups.This method of salary distribution means that Macro possibly be in the same interference group with some LPN, belongs to low and disturbs.

Step 204, Macro, communicate so that each LPN passes through running time-frequency resource that is distributed and the UE that is attached to each LPN for each LPN in the network distributes running time-frequency resource according to distributing the quadrature running time-frequency resource between difference interference group.

After each LPN and Macro all were assigned to different interference groups, Macro was each LPN and Macro distribution running time-frequency resource according to the basic principle of distributing the quadrature running time-frequency resource between difference interference group.

For between the less LPN of potential interference or LPN and Macro, can use nonopiate running time-frequency resource, also can use orthogonal time frequency resources.Wherein,, improve the running time-frequency resource utilance in order better to support between the LPN or the durability of the running time-frequency resource between LPN and the Macro, between the less LPN of potential interference or LPN and Macro to distribute nonopiate running time-frequency resource be a kind of preferred implementation.Therefore, the Macro of present embodiment is according to distributing nonopiate running time-frequency resource, for each LPN in the same interference group distributes running time-frequency resource in the same interference group.

In conjunction with Figure 1A-Fig. 1 C illustrated embodiment; The resource allocation methods of present embodiment specifically is meant to be that a UE selects a LPN as its point of network attachment, when a LPN and a UE communicate, at first through dividing the interference group; Interference group according to LPN place; According to the nonopiate running time-frequency resource of distribution in the same interference group, and distributing the quadrature running time-frequency resource between different interference group, is that a LPN distributes running time-frequency resource.

The resource allocation methods that present embodiment provides has promptly reduced between potential each LPN or the interference between LPN and the Macro, guarantees again obtaining the channeling gain between these LPN or between LPN and the Macro.

Further, in the above-described embodiments, for and Macro exist between potential strongly disturbing LPN and the Macro, can also adopt soft orthogonal time frequency resources.So-called soft orthogonal time frequency resources is meant for being in each LPN in the different interference groups with Macro; Macro for those LPN distribute with Macro in the corresponding running time-frequency resource of edge UE orthogonal time frequency resources mutually; And can be and the non-orthogonal running time-frequency resource of those LPN also can be orthogonal time frequency resources for the corresponding running time-frequency resource of the center UE among the Macro.

Based on above-mentioned, Macro needs each UE that will be attached to Macro in advance to be divided into edge UE and center UE.Usually; Macro adopts signal to noise ratio (the Signal-to-Noise Ratio of each UE of the access Macro that will get access to; SNR) compare with signal-noise ratio threshold; Perhaps macro adopts Signal to Interference plus Noise Ratio (the Signal-to-Interference-Noise Ratio of each UE that will insert Macro; SINR) compare with the Signal to Interference plus Noise Ratio thresholding, perhaps macro adopts the channel quality indication of each UE of the access Macro that will get access to (Channel Quality Indicator CQI) compares with channel quality indication thresholding; Signal strength signal intensity and the signal strength threshold of each UE of the access Macro that perhaps will get access to compare, and confirm edge UE and center UE among the Macro according to comparative result.If the SINR of UE is greater than signal-noise ratio threshold, then this UE is center UE, otherwise this UE is edge UE.If the signal strength signal intensity of UE is greater than signal strength threshold, then this UE is center UE, otherwise this UE is edge UE.

If the LPN among above-mentioned Figure 1A-Fig. 1 C is in the different interference groups with Macro; Then Macro can for first LPN distribute with Macro in the corresponding running time-frequency resource of edge UE orthogonal time frequency resources mutually; So that a LPN through the corresponding running time-frequency resource of the edge UE that is assigned to among the Macro mutually orthogonal time frequency resources communicate by letter with a UE, reduce the interference between a Macro and the LPN.Promptly a LPN carries out scheduling of resource and the distribution of a UE on the running time-frequency resource that is assigned to.

At present, 3GPP discussing carrier aggregation (Carrier Aggregation, CA) technology, thereby the polymerization of CA through different carrier forms multi-carrier transmission, can further improve network capacity.Wherein, different carrier can be the continuous or discrete frequency band that is positioned at same frequency range or different frequency range.For example, the application scenarios of the HetNet among a kind of CA provides the covering of Macro for carrier wave F1, and carrier wave F2 provides the covering of each LPN, and wherein mobility covers also based on carrier wave F1.Wherein, carrier wave F1 is 800 megahertzes (MHz) and 2GHz, and carrier wave F2 is 3.5GHz.But at present do not provide Macro in the application scenarios of HetNet and LPN is the efficient communication method under the multicarrier situation, more be not given in methods such as resource allocation under the multicarrier situation, network attachment point selection.

To the problems referred to above, the embodiment of the invention provides a kind of communication means of HetNet multi-carrier.The communication means of this multicarrier relates generally to how each UE selects point of network attachment in the network, how to improve network capacity, how to reduce Communication Jamming, the solution of aspect problem such as Resources allocation how.

At first, the embodiment of the invention provides a kind of network architecture of the resource of frequency for a long time, and is referred to as Ccell (aggregation cell) or Cnet (polymeric network) or Hicell (floored community).Wherein, " C " among Ccell or the Cnet is appreciated that to covering (coverage), capacity (capacity), converge (coverged), cooperate (cooperative), gather (collective), coordinating (coordinated) or cloud (cloud) or multipoint cooperative transmission (CoMP); " Hi " among the Hicell is appreciated that to layering (Hierarchical), super (Hyper) or mixes (Hybrid).This network architecture of Ccell that the embodiment of the invention provides or Cnet or Hicell can be counted as by cover layer and capacity layer form or by the basic communication layer with strengthen that communication layers is formed or form or form by general communication layers and private communication layer etc. by common communications layer and specific communication layer or by common communication layer and private communication layer.That is to say, the network architecture under the multicarrier that the embodiment of the invention provides, promptly Ccell or Cnet or the Hicell network architecture are made up of two-layer.In order to be without loss of generality, the embodiment of the invention is with this two-layer called after first resource layer and second resource layer respectively.

When a plurality of running time-frequency resources were made up of carrier resource, these corresponding two resource layers were the first carrier layer and the second carrier wave layer, on first carrier layer and the second carrier wave layer employed carrier set or frequency range set different, and employed power also can difference.The embodiment of the invention provides the definition mode of the two kinds of relevant first carrier layers and the second carrier wave layer.A kind of definition mode is: according to the size of Macro and the employed carrier wave/frequency range of LPN, all carrier wave/frequency ranges are divided, form the first carrier layer and the second carrier wave layer.For example, first carrier layer cover layer is that carrier set 1/ frequency range set 1 is formed, and the second carrier wave layer is that carrier set 2/ frequency range set 2 is formed.Another kind of definition mode is: according to the power of Macro on employed each carrier wave/frequency range, Macro and employed all the carrier wave/frequency ranges of LPN are divided, form the first carrier layer and the second carrier wave layer.For example, first cover layer is the corresponding coverage of low-power resource transmission, and second cover layer is the corresponding coverage of high power resource transmission.

If a plurality of running time-frequency resource layers are made up of sub-frame resources, these corresponding two resource layers are the first subframe layer and the second subframe layer, and employed subframe set or subframe type are different on the first subframe layer and the second subframe layer, and employed power also can difference.A kind of definition mode is: according to subframe type subframe is divided into normal sub-frames and ABS subframe or MBSFN subframe or reduces the ABS subframe of power or the MBSFN subframe of reduction power.Can use ABS subframe or ABS subframe that reduces power or the MBSFN subframe that reduces power for the first subframe layer.Can use in top four kinds of subframes one or more for the second subframe layer.The ABS subframe that reduces power can be to carrying out Power Limitation except CRS and common signal channel and all channels the synchronizing channel or signal in the ABS subframe, making its transmitted power be lower than certain threshold value.Be typically at least and need reduce transmission or/and DMRS carries out power CSI-RS.For example Macro is configured to reduce the ABS subframe of power at the first subframe layer, and LPN is configured to the ABS subframe at the first subframe layer.Macro and LPN are configured to normal sub-frames and/or MBSFN subframe at the second subframe layer.At the first subframe layer, Macro and LPN all can send signal or channel to the UE that is attached to Macro or LPN, such as ePDCCH, CSI-RS, USRS or PDSCH etc.Owing to Macro sends with the ABS subframe that reduces power in the corresponding subframe of LPN, for example be used to the better UE service of its channel quality, thereby reduced interference the UE under the LPN like high SINR, make LPN obtain higher capacity at the first subframe layer.Wherein, " power " during " power " above in the said reduction power or power reduce is meant the transmitted power of Macro signal or channel on the first subframe layer.

If said a plurality of running time-frequency resource is made up of carrier resource and sub-frame resources, two corresponding combinations that resource layer can be carrier wave layer and subframe layer.For example; Macro is according to the size or the power of Macro on each carrier wave of the frequency of a plurality of carrier waves; A plurality of carrier waves are divided into the first carrier layer and the second carrier wave layer, and Macro is the first subframe layer and the second subframe layer according to the type of each sub-frame with a plurality of sub-frame division; Macro with the first subframe layer of the first carrier layer and the second carrier wave layer as first resource layer, with the second subframe layer of the second carrier wave layer as second resource layer.At the first carrier layer of first resource layer, Macro can reduce its transmitted power, can send ePDCCH, CSI-RS, USRS or PDSCH etc., does not perhaps send PDCCH or CRS.At the first subframe layer of the second carrier wave layer of first resource layer, Macro can reduce channel or the transmitted power of signal except that CRS, common signal channel and synchronizing channel, for example reduces the transmitted power of CSI-RS, makes it be lower than certain threshold value.Second resource layer promptly the second subframe layer of the second carrier wave layer can be configured to normal sub-frames or MBSFN subframe etc. and communicate.

In addition, the communication means among Ccell or Cnet or the Hicell also can be called floored community (LayerCell) or layering carrier wave (LayerCarrier) or carrier wave (FlexCarrier or Flexcarrier) or sub-district (FlexCell or Flexcell) or communication means or carrier wave/sub-district (FlexC) (C wherein has identical implication with the C of front Ccell) etc. flexibly of carrier aggregation net (Flex carrier A Net or FCAN) flexibly flexibly flexibly.

Below at first through specific embodiment explanation under multicarrier in the HetNet application scenarios UE select the method for point of network attachment, in following embodiment, still inserting a LPN with a UE and a UE is that example describes.In addition; Only the example explanation in following embodiment with the carrier wave; Frequency range and carrier wave have similar processing procedure; Carrier wave layer and resource layer or subframe layer have similar processing procedure, and further the processing of various first resource layers is similar to the processing of first carrier layer, and the processing of various second resource layers is similar to the second carrier wave layer.

Fig. 3 A is the flow chart of the communication means that provides of fifth embodiment of the invention.Shown in Fig. 3 A, the method for present embodiment comprises:

Step 301, Macro are divided into the first carrier layer and the second carrier wave layer according to the size or the power of Macro on each carrier wave of the frequency of a plurality of carrier waves with a plurality of carrier waves.

At first, Macro divides the employed a plurality of carrier waves of each LPN in Macro and the LPN place network according to the definition to the first carrier layer and the second carrier wave layer.

When dividing with first kind of definition mode; Macro compares the frequency of a plurality of carrier waves respectively with preset carrier frequency thresholding; A plurality of carrier wave medium frequencys are divided into the first carrier layer greater than the carrier wave of carrier frequency thresholding; The carrier wave that a plurality of carrier wave medium frequencys are less than or equal to the carrier frequency thresholding is divided into the second carrier wave layer; And be provided with Macro in the transmitted power on each carrier wave on the first carrier layer less than the transmitted power of Macro on each carrier wave on the second carrier wave layer, so that the first carrier layer and the second carrier wave layer satisfy the power requirement in the definition.Wherein, the carrier frequency thresholding can be provided with according to concrete network application adaptability by Macro, its occurrence is not done qualification at this.

When dividing with second kind of definition mode; Macro compares the transmitted power of Macro on each carrier wave and preset power threshold; The pairing carrier wave of power that will be less than or equal to power threshold is divided into the first carrier layer, will be divided into the second carrier wave layer greater than the corresponding carrier wave of the power of power threshold.The transmitted power of each carrier wave is less than the transmitted power of each carrier wave on the second carrier wave layer on the first carrier layer that marks off with this mode.

Wherein, the transmitted power of Macro on each carrier wave of first carrier layer is identical, and its transmitted power on each carrier wave of the second carrier wave layer is also identical.With the transmitted power of Macro on each carrier wave of first carrier layer, abbreviate the power of Macro on the first carrier layer as, with the transmitted power of Macro on each carrier wave of the second carrier wave layer, abbreviate the power of Macro on the second carrier wave layer as.Wherein, Macro at the power on the first carrier layer less than its power on the second carrier wave layer.

Wherein, the power of each LPN on each carrier wave of first carrier layer, with and power on each carrier wave of the second carrier wave layer all identical.With the power of each LPN on each carrier wave of first carrier layer, abbreviate the power of each LPN on the first carrier layer as, with the power of LPN on each carrier wave of the second carrier wave layer, abbreviate the power of each LPN on the second carrier wave layer as.Be that each LPN is identical with its power on the second carrier wave layer at the power on the first carrier layer.

In this explanation, a plurality of carrier waves in the present embodiment are not limited to 2, that is to say that the carrier wave on each carrier wave layer can be more than 1 or 2 or 2.The carrier wave that each carrier wave layer is comprised can be discontinuous frequency range, and for example, the carrier wave on the first carrier layer comprises the frequency spectrum of 3.6GHz, and the carrier wave on the second carrier wave layer comprises the frequency spectrum of 800MHz and 900MHz.Wherein because high frequency carrier is littler than the coverage of low frequency carrier signal, therefore, generally with high frequency carrier as the first carrier layer, be used to improve network capacity, and with low frequency carrier signal as the second carrier wave layer, in order to improve network coverage.

For carrier bandwidths or the carrier wave number on the first carrier layer or the second carrier wave layer, can be configured based on its loaded service amount or resource utilization or load.For example, traffic carrying capacity is higher or resources occupation rate is higher or load when heavy on the second carrier wave layer, can be the big bandwidth or the more carrier wave number of carrier wave configuration of the second carrier wave layer; But when there not being the idle carrier resource time spent; Also can the carrier wave of first carrier layer be configured in the carrier set of the second carrier wave layer; For example; The carrier wave of the first carrier layer of big bandwidth is configured to the carrier wave of the second carrier wave layer, and the carrier wave of the second carrier wave layer of little bandwidth is configured to the carrier wave of first carrier layer.Extreme case can also all be configured to all carrier resources the carrier wave of the second carrier wave layer.

Step 302, Macro be according to the speed of each UE in the ability of each UE in the network and/or the network, each UE is divided into moves the UE group, 1 group of UE ability and 2 groups of UE abilities.

Further, multicarrier is being divided into two carrier wave layers, is being responsible for respectively promoting after network capacity and the network coverage, Macro reports through the ability of each UE, obtains the ability of each UE, and through each UE is carried out speed monitoring, obtains the speed of each UE; Then, according to ability and/or the speed of each UE, the UE under Ccell or the Hicell network (i.e. the network at LPN place) is divided into groups.In the present embodiment, UE is divided into 1 group of UE ability, moves 2 groups of UE group and UE abilities.For a kind of method of the ability of UE can be the type according to UE, arrives type 8 such as the Class1 of stipulating in the standard, thereby can confirm that this UE is 1 group of UE of ability or 2 groups of UE of ability.Different types can belong to the different ability group.Wherein, type is that 6,7,8 UE belongs to Rel-10UE, and the UE of Class1～5 is the UE before the Rel-10.A kind of point-score be with Class1～5 as 1 group of ability, the UE of type 6～8 is as 2 groups of abilities.Perhaps the UE type of standard redetermination Rel-11 is such as type 9～N, and N＞=9 then can be with UE Class1～8 as ability group 1, and with UE type 9～N as ability group 2.Also can be called legacy UE group with 1 group of ability this moment, and 2 groups of abilities are called non-legacy UE group.For the other a kind of method of the ability of UE be combine UE type and/or with the type of UE independent parameter mutually, such as whether UE being supported ePDCCH and/or to measurement more than the CSI-RS of 1 non-0 (non-zero) through-put power.For not supporting ePDCCH and/or to more than the UE of the measurement of the CSI-RS of 1 non-0 (non-zero) through-put power UE as ability group 1; For supporting ePDCCH and/or to more than the UE of the measurement of the CSI-RS of 1 non-0 (non-zero) through-put power UE as ability group 2.

Wherein, move the UE that comprises in the UE group and be meant the UE of speed greater than certain translational speed (for example a certain speed threshold).Present embodiment can be realized the high efficiency of each UE in the LTE system is covered with reliable through dividing different UE groups.

In the present embodiment, UE is divided for UE group 1, UE group 2 and mobile UE group, but be not limited thereto such as can further segmenting the UE ability, thereby mark off more group.Access on the carrier wave layer can be compared flexibly for grouping UE, for example, when on the second carrier wave layer, being free over-carriage ripple resource or resource utilization to be lower than certain value, according to the supportable of UE, can increase corresponding UE group.

In order to realize to comprise the legacy carrier wave on the second carrier wave layer of present embodiment, so that the backwards compatibility to UE in 1 group of Legacy UE or the ability to be provided to the support of UE in 1 group of the UE ability.In order to realize support to UE in 2 groups of the UE abilities; Can comprise non-legacy carrier wave or extra carrier type or legacy carrier wave on the first carrier layer of present embodiment; With further reduction expense; Such as adopt to reduce or do not send CRS, thereby more performance is provided for the UE of 2 groups of UE abilities.That is to say, comparatively preferred embodiment be: adopting the second carrier wave layer is 1 group of service of UE ability for moving the service of UE group or adopting the second carrier wave layer, is 2 groups of services of UE ability and adopt the first carrier layer.

Wherein, when adopting the second carrier wave layer,, also can be certain LPN that is on the second carrier wave layer for its service object can be the Macro that is on the second carrier wave layer for mobile UE group or for 1 group of service of UE ability.When adopting the first carrier layer to be 2 groups of services of UE ability,, also can be certain LPN that is on the first carrier layer for its service object can be the Macro that is on the first carrier layer.

Step 303, Macro judge whether a UE belongs to 2 groups of UE abilities, if judged result is for denying execution in step 304; If judged result is for being execution in step 305.

Based on above-mentioned, Macro judges that a UE is divided in 2 groups of the UE abilities, still is divided in two other UE group, so that confirm to give a UE that the Macro or the employed carrier resource of LPN of service are provided.

Step 304, Macro control Macro and each LPN communicate with a UE on the second carrier wave layer, and execution in step 306.

When Macro judges a UE not in 2 groups of UE abilities, when promptly a UE was in 1 group of UE ability or mobile UE group, then Macro preferably controlled Macro itself and communicates with a UE on the second carrier wave layer with each LPN, with the coverage of raising network.This step described " each LPN " mainly is meant the LPN that a UE is inserted, and promptly indicates a LPN on its second carrier wave layer, to carry out the transmission of data or control channel with a UE.

Wherein, Each LPN of Macro control comprises that mainly Macro is that a UE distributes the resource on the second carrier wave layer communicating with a UE on the second carrier wave layer; And be advertised as the resource on the second carrier wave layer that a UE distributed, thereby a LPN and a UE can communicated on corresponding resource to each LPN.

Step 305, Macro control Macro and each LPN communicate with a UE on the first carrier layer, and execution in step 306.

When Macro judges a UE in 2 groups of UE abilities the time, then Macro preferably controls Macro itself and communicates with a UE on the first carrier layer with each LPN, to improve network capacity, reduces the power overhead of network.This step described " each LPN " equally mainly is meant the LPN that a UE is inserted, and promptly indicates a LPN on its first carrier layer, to carry out the transmission of data or control channel with a UE.

Wherein, Each LPN of Macro control comprises that mainly Macro is that a UE distributes the resource on the first carrier layer communicating with a UE on the first carrier layer; And be advertised as the resource on the first carrier layer that a UE distributed, thereby a LPN and a UE can communicated on corresponding resource to each LPN.

Present embodiment is through above-mentioned steps 301-step 305; Use simultaneously under the scene of a plurality of carrier waves at Macro and each LPN; Be that a UE has selected Macro and each LPN and a UE to communicate employed carrier wave or frequency resource, for the step of follow-up selection point of network attachment lays the foundation.

Step 306, Macro obtain Macro and an out-hole run information LPN; Perhaps Macro obtain difference that UE sends corresponding Macro with a down-run survey information LPN, perhaps Macro obtains Macro and an out-hole run information LPN and corresponding Macro and a down-run survey information LPN.

Step 307, Macro to Macro's and/or the out-hole run information of a LPN carry out bias treatment; Perhaps to Macro's and/or the down-run survey information of a LPN carry out bias treatment, perhaps to Macro's and/or the out-hole run information of a LPN and corresponding Macro's and/or a corresponding LPN's down-run survey information carry out bias treatment respectively.

Step 308, Macro select a LPN or the Macro point of network attachment as a UE according to the bias treatment result, so that a UE communicates through point of network attachment.

Above-mentioned steps 306-step 308 can repeat no more at this referring to the corresponding description of Figure 1A-Fig. 1 C illustrated embodiment.

If forward step 306 to by step 304, and carry out subsequent step 307 and step 308, then in operating process shown in the step 306-step 308, a Macro and a LPN communicate with a UE on the second carrier wave layer.For example a Macro and a LPN use carrier wave and power on the second carrier wave layer to send downstream signal to a UE, and receive the feedback information of a UE.

If forward step 306 to by step 305, and carry out subsequent step 307 and step 308, then in operating process shown in the step 306-step 308, a Macro and a LPN communicate with a UE on the first carrier layer.For example a Macro and a LPN use carrier wave and power on the first carrier layer to send downstream signal to a UE, and receive the feedback information of a UE.

In the present embodiment; At first, then the UE in the network is divided into groups, after confirming the UE group at each UE place through carrying out layering with a plurality of carrier waves LPN to Macro; Communicate with employed carrier wave and frequency resource for UE selection Macro with LPN according to the UE group at UE place; Promptly at first confirm the carrier wave layer that UE is inserted, for UE selects point of network attachment, solved the problem of UE selection point of network attachment under the multicarrier environment then; Realized making UE as much as possible to select LPN simultaneously, improved sub-district or regional split gain from LPN as point of network attachment.

Fig. 3 B is the flow chart of the communication means that provides of sixth embodiment of the invention.Present embodiment realizes that based on Fig. 3 A illustrated embodiment shown in Fig. 3 B, the method for present embodiment comprised before step 304:

Step 304a, Macro judge Macro in the resource utilization on the second carrier wave layer or Macro and the resource utilization sum of each LPN on the second carrier wave layer whether greater than the utilance thresholding; If judged result is for denying execution in step 304; If judged result is for being execution in step 305.

Wherein, Macro is obtained in resource utilization on the second carrier wave layer and the resource utilization addition of each LPN on the second carrier wave layer by Macro in the resource utilization sum on the second carrier wave layer with each LPN.

Further, Macro can also judge whether Macro is less than or equal to the utilance thresholding in resource utilization on the first carrier layer or Macro with the resource utilization sum of each LPN on the first carrier layer; If if judged result is for denying execution in step 304; If judged result is for being execution in step 305.

Wherein, Macro is obtained in resource utilization on the first carrier layer and the resource utilization addition of each LPN on the first carrier layer by Macro in the resource utilization sum on the first carrier layer with each LPN.

Further, the method for present embodiment is compared with Fig. 3 A illustrated embodiment, before step 305, also comprises:

Step 305a, Macro judge Macro in the resource utilization on the first carrier layer or Macro and the resource utilization sum of each LPN on the first carrier layer whether greater than the utilance thresholding; If judged result is for denying execution in step 305; If judged result is for being execution in step 304.

Further, Macro can also judge whether Macro is less than or equal to the utilance thresholding in resource utilization on the second carrier wave layer or Macro with the resource utilization sum of each LPN on the second carrier wave layer; If judged result is for denying execution in step 305; If judged result is for being execution in step 304.

In the present embodiment; Adjust according to the resource utilization of the Macro carrier wave layer that uses of communicating by letter with UE; Realized the priority of the attached first carrier layer of grouping UE and the second carrier wave layer to a certain extent; That is to say,, allow the UE ability preferentially to insert the first carrier layer for 2 groups though the first carrier layer has lower expense; When but perhaps the resource utilization of the second carrier wave layer is lower than certain value when the resource utilization of first carrier layer reaches certain value, just to 2 groups of accesses of carrying out the second carrier wave layer of UE ability; And also be when having only the resource utilization of the second carrier wave layer to reach certain value for the second carrier wave layer or the resource utilization of first carrier layer when being lower than certain value; Just 1 group of UE ability or mobile UE are carried out the access of first carrier layer; Thereby make the resource of the second carrier wave layer to make full use of, also help the advantage of first carrier layer performance low-power saving power resource.

In this explanation, in some cases, can include only above-mentioned steps 304a and step 305a one of them.

Further, except UE being divided into groups and selects according to the access that the UE group result is carried out the carrier wave layer, can also be through channel be divided into groups, and select based on the access that the group result of channel is carried out the carrier wave layer.Wherein, can divide into groups to channel, for example, channel is divided into common signal channel (for example control channel) and dedicated channel (for example Traffic Channel or data channel) based on business.Common signal channel is adopted same running time-frequency resource transmission or employing broadcast mode or adopted the multicast mode to send by Macro and LPN, can on the second carrier wave layer, send by Macro and LPN.Dedicated channel adopted by Macro send separately or send separately or send with the mode of LPN cooperation transmission by Macro by LPN.Further, can be non-broadcast mode to the transmission of dedicated channel, promptly do not need all LPN and Macro under the Macro on identical running time-frequency resource, one to be all UE and to send.Wherein, to dedicated channel can be by Macro independent or LPN separately or Macro cooperate with LPN and on the first carrier layer, send.The method of classifying based on business here is with top method of classifying based on UE contradiction not.For example, can be applied to the UE of static/low speed here based on the classification of business, and move/control channel and the data channel of UE at a high speed still can adopt the mode of broadcasting to send.

Above-mentioned each embodiment or execution mode have realized under the multicarrier environment, making UE as much as possible to select LPN as point of network attachment, will introduce the lifting of multicarrier environment lower network capacity and the saving problem of power resource below.

In embodiments of the present invention, for the first carrier layer, what emphasis will solve is the lifting problem of capacity.When the dense degree (abbreviating focus as) that surpasses some or UE when the number of LPN in the network reaches and can be covered by LPN; Can reduce in the transmitted power of first carrier layer Macro; Increase the covering of LPN newly, not only can promote network capacity but also can the saving power resource UE.

In embodiments of the present invention, regulation Macro in the power bracket on the first carrier layer is: higher limit is the transmitted power (abbreviate power) of Macro on the second carrier wave layer, and lower limit is the transmitted power of LPN.

Based on above-mentioned, seventh embodiment of the invention provides a kind of Macro of reduction the execution mode of the power on the first carrier layer, and is as shown in Figure 4, and this execution mode comprises:

Corresponding path loss or RSRP or the SINR of each UE on the first carrier layer of step 401, Macro statistics access Macro, and from statistics, obtain greatest path loss or minimum RSRP or minimum SINR.

In the aforementioned embodiment, Macro determines the carrier wave layer that each UE inserts according to the UE group at UE place.So in the present embodiment; Macro can be according to each UE various signals or the channel in communication process of Macro with the first carrier layer that inserts Macro; Within a certain period of time, information such as the RSRP of the path loss of each UE of statistics access under Macro first carrier layer or pilot signal or SINR.Then, Macro obtains greatest path loss or minimum RSRP or minimum SINR from the RSRP or SINR of the path loss of each UE of counting on or pilot signal.

Step 402, Macro reduce the power of Macro on the first carrier layer according to greatest path loss or minimum RSRP or minimum SINR.

After obtaining greatest path loss or minimum RSRP or minimum SINR, Macro reduces the power of Macro on the first carrier layer based on the greatest path loss of obtaining or minimum RSRP or minimum SINR.For example; Macro can be according to greatest path loss or minimum RSRP or minimum SINR; Dynamically adjust within the power bracket on the first carrier layer at Macro, even can turn off the power (this moment, Macro was 0 in the lower transmit power limit value of first carrier layer) of first carrier layer.

Present embodiment provides a kind of Macro according to according to greatest path loss or minimum RSRP or minimum SINR, reduces the execution mode of the power of Macro on the first carrier layer, and this execution mode comprises:

It is the power of Macro on the second carrier wave layer in the power upper limit value on the first carrier layer that step 4021, Macro are provided with Macro; And be provided with the power lower limit of Macro on the first carrier layer for each LPN on the first carrier layer or the power on the second carrier wave layer, it is 0 that Macro power lower limit on the first carrier layer perhaps is set.Wherein, if the resource utilization of Macro on the first carrier layer is lower than certain value within a certain period of time, then the power of Macro on the first carrier layer might be 0.

Step 4022, Macro carry out the power grade division according to the power upper limit value and the power lower limit of Macro on the first carrier layer, and path loss thresholding or RSRP thresholding or the SIRN thresholding corresponding to each power grade are set.

Concrete, Macro is divided into some grades with its reducible power, suppose with the power bracket of Macro on the first carrier layer be divided into successively from higher limit to the power lower limit PA, PB ..., PN, promptly be divided into N power grade.Wherein, the power of Macro on the second carrier wave layer is Macro power upper limit value on the first carrier layer, and that corresponding can be P _A, power or the performance number 0 of each LPN on the first carrier layer or the second carrier wave layer is the lower limit of the power of Macro on the first carrier layer, that corresponding can be P _NThen, if be benchmark with the greatest path loss, then Macro is provided with the corresponding path loss thresholding of this N power grade respectively, and is designated as A _PL, B _PL..., N _PLIf with minimum RSRP is benchmark, then Macro is provided with the corresponding RSRP thresholding of this N power grade respectively, and is designated as A _RSRP, B _RSRP..., N _RSRPIf with minimum SINR is benchmark, then Macro is provided with the corresponding SINR thresholding of this N power grade respectively, and is designated as A _SINR, B _SINR..., N _SINR

Step 4023, Macro compare greatest path loss with the path loss thresholding of corresponding each power grade; Obtaining less than greatest path loss and with greatest path loss and differ minimum path loss thresholding, is the corresponding power grade of path loss thresholding that is obtained with the power setting of Macro on the first carrier layer; Perhaps; Macro compares minimum RSRP with the RSRP thresholding of corresponding each power grade; Obtaining greater than minimum RSRP and with minimum RSRP and differ minimum RSRP thresholding, is the corresponding power grade of RSRP thresholding that is obtained with the power setting of Macro on the first carrier layer; Perhaps; Macro compares minimum SINR with the SINR thresholding of corresponding each power grade; Obtaining greater than minimum SINR and with minimum SINR and differ minimum SINR thresholding, is the corresponding power grade of SINR thresholding that is obtained with the power setting of Macro on the first carrier layer.

Concrete, if be benchmark with the greatest path loss, Macro compares greatest path loss with the path loss thresholding of corresponding each power grade, if greatest path loss＞A _PL, then Macro reduces its power on the first carrier layer to P _AIf B _PL＜greatest path loss＜A _PL, then Macro reduces its power on the first carrier layer to P _BSo, work as N _PLDuring＜greatest path loss, then Macro reduces its power on the first carrier layer to P _N

If with minimum RSRP is benchmark, Macro compares minimum RSRP with the RSRP thresholding of corresponding each power grade, if B _RSRP＜minimum RSRP＜A _RSRP, then Macro reduces its power on the first carrier layer to P _ASo, as minimum RSRP＜N _RSRPThe time, then Macro reduces its power on the first carrier layer to P _N

If with minimum SINR is benchmark, Macro compares minimum SINR with the SINR thresholding of corresponding each power grade, if B _SINR＜minimum SINR＜A _SINR, then Macro reduces its power on the first carrier layer to P _ASo, as minimum SINR＜N _SINRThe time, then Macro reduces its power on the first carrier layer to P _N

In said process; The initial power of Macro on the first carrier layer is normally greater than the corresponding power of greatest path loss or minimum RSRP or minimum SINR; Therefore, present embodiment is provided with the power of Macro on the first carrier layer according to greatest path loss or minimum RSRP or minimum SINR, can reduce the power of Macro on the first carrier layer; And through reducing the power of Macro on the first carrier layer, realized the purpose of lifting capacity, saving power resource.

Further, in this explanation, through adopting and reducing Macro at the similar power of method each LPN of reduction on the first carrier layer of the power on the first carrier layer, with further saving power resource.After overpower reduced, each LPN was can be different with the power on the second carrier wave layer on the first carrier layer.

In the foregoing description, be that example is illustrated with the first carrier layer and the second carrier wave layer, still, the first carrier layer and the second carrier wave layer can be replaced by first resource layer and second resource layer in the foregoing description.The technical scheme that cell ID is set below goes for the first carrier layer and the second carrier wave layer.

In the above-described embodiments; Each LPN can be identical at cell ID on the first carrier layer and the cell ID of Macro on the first carrier layer; Also can be inequality; Each LPN can be identical at cell ID on the second carrier wave layer and the cell ID of Macro on the second carrier wave layer, also can be inequality.But; Because LPN has different cell ID with Macro and can cause the UE of high-speed mobile between Macro and LPN, to carry out frequent switching; Frequent switching can cause the consumption of network side resource and the reduction of UE side user impression; Therefore, should reduce switching frequency as the second carrier wave layer that promotes coverage as far as possible.

To the problems referred to above, present embodiment can be arranged on each LPN on the second carrier wave layer and have identical cell ID with Macro on the second carrier wave layer, thereby avoids frequent switching.At this moment, on the second carrier wave layer, each LPN has the cell ID identical with Macro.

Further, Macro each LPN that can also be arranged on the first carrier layer has identical cell ID with Macro on the first carrier layer.

Further, Macro reduces after the power of Macro on the first carrier layer according to greatest path loss or minimum RSRP or minimum SINR; Macro interference to each LPN on the first carrier layer is less; Therefore, each LPN that Macro can be arranged on the first carrier layer has different cell ID with Macro on the first carrier layer, and the cell ID that is provided with between each LPN is also different; At this moment; On the first carrier layer, use different cell ID, first carrier layer can obtain sub-district or regional split gain completely between each LPN and between each LPN and the Macro.

Among the embodiment, on the second carrier wave layer, each LPN has adopted the cell ID identical with Macro to avoid frequent switching in the above.But in real network; Can distribute carry out cell ID at each LPN on the first carrier layer and on the second carrier wave layer as required; Through identical cell ID is traded off with different cell ID; Promptly each LPN under the Macro is adopted and mix the cell ID method of salary distribution, so not only can take into account network performance but also can take into account performance of handoffs.Based on this, following examples of the present invention provide a kind of method of Macro under the multicarrier environment with each LPN distribution cell ID that be.

Fig. 5 B is the flow chart of the another kind of cell ID distribution method that provides of eighth embodiment of the invention.Shown in Fig. 5 B, the method for present embodiment comprises:

Step 501b, Macro obtain in the 3rd down-run survey information of the Macro on the first carrier layer and the 3rd down-run survey information of each LPN on the first carrier layer.

Wherein, the 3rd down-run survey signal at per two LPN on the first carrier layer is that same UE measures the downstream signal that these two LPN on the first carrier layer send respectively; Macro on the first carrier layer and the 3rd down-run survey information any one LPN are that same UE measures with the downstream signal that this LPN sends Macro respectively.Wherein, UE can feed back to Macro and LPN after measuring Macro and the 3rd down-run survey information LPN.LPN can report Macro after receiving that UE sends to its 3rd down-run survey information.

Step 502b, Macro will compare in the 3rd down-run survey information of the 3rd down-run survey information of the Macro on the first carrier layer and each LPN on the first carrier layer; And the 3rd down-run survey information of per two LPN that will be on the first carrier layer compares, and is that Macro and LPN are provided with cell ID according to comparative result.

Wherein, Macro will comprise in the process that the 3rd down-run survey information of the Macro on the first carrier layer and the 3rd down-run survey information at a LPN on the first carrier layer compare: Macro at first will the 3rd down-run survey information of the 3rd down-run survey information of the Macro on the first carrier layer and the LPN that compare all with preset the second measurement thresholding and compare; If the 3rd down-run survey information of the 3rd down-run survey information of the Macro on the first carrier layer and the LPN that is compared is all greater than the second preset measurement thresholding, Macro continues and will compare with preset second difference threshold in the difference with the 3rd down-run survey information LPN that is compared the Macro on the first carrier layer; If the difference of the Macro on the first carrier layer and the 3rd down-run survey information LPN that is compared is less than preset second difference threshold, Macro by the Macro on the first carrier layer with the LPN of comparison different cell ID is set.

The process that Macro will compare in the 3rd down-run survey information of two LPN on the first carrier layer comprises: the 3rd down-run survey information of two LPN that Macro at first will be on the first carrier layer is all measured thresholding and is compared with second; If the 3rd down-run survey information of these two LPN on the first carrier layer is all measured thresholding greater than second, the difference that Macro continues the 3rd down-run survey information of these two LPN that will be on the first carrier layer compares with preset second difference threshold; If the difference of the 3rd down-run survey information of these two LPN on the first carrier layer is less than second difference threshold, Macro is provided with different cell ID for these two LPN on the first carrier layer.

In other cases, Macro is provided with identical cell ID for these two LPN.

Wherein, the downstream signal of Macro and LPN transmission can be CSI-RS or USRS.

In the present embodiment; Each LPN that Macro measures according to the measurement result of upward signal that UE is sent or channel or according to UE and the downstream signal of Macro feed back; Through comparing with preset measurement thresholding and difference threshold; On the first carrier layer, carry out the distribution of cell ID for LPN and Macro; Make on the first carrier layer, not only to have identical cell ID but also have different cell ID, promptly accomplished distribution, reached the purpose that not only can take into account network performance but also can take into account performance of handoffs the cell ID of each LPN under the Macro through mixing the cell ID method of salary distribution.

Further, Macro can be each LPN and Macro distribution cell ID on the first carrier layer through mixing the cell ID method of salary distribution not only, can adopt this mode to be each LPN on the second carrier wave layer and Macro distribution cell ID equally.Wherein, Macro is through mixing the cell ID method of salary distribution for distributing a kind of execution mode of cell ID to comprise at each LPN on the second carrier wave layer and Macro: Macro obtains in the 4th out-hole run information of the Macro on the second carrier wave layer and the 4th out-hole run information of each LPN on the second carrier wave layer.Wherein, The 4th out-hole run signal of per two LPN on the second carrier wave layer is that these two LPN measure upward signal or the channel that same UE sends respectively, and the Macro on the second carrier wave layer and the 4th out-hole run information any one LPN are that Macro measures upward signal or the channel that same UE sends respectively with this LPN.

Then; Macro will compare in the 4th out-hole run information of the 4th out-hole run information of the Macro on the second carrier wave layer and each LPN on the second carrier wave layer; If the 4th out-hole run information of the Macro on the second carrier wave layer is all measured thresholding greater than the preset the 3rd with the 4th out-hole run information of the LPN that is compared; And the difference of Macro and the 4th out-hole run information LPN that is compared on the second carrier wave layer is less than preset the 3rd difference threshold, Macro by the Macro on the second carrier wave layer with the LPN of comparison different cell ID is set.

Then; Macro will compare in the 4th out-hole run information of per two LPN on the second carrier wave layer; If the 4th out-hole run information of these two LPN on the second carrier wave layer is all measured thresholding greater than the 3rd; And the difference of the 4th out-hole run information of these two LPN on the second carrier wave layer is less than the 3rd difference threshold, and Macro is provided with different cell ID for these two LPN on the second carrier wave layer.

Another kind of execution mode is: Macro obtains in the 4th down-run survey information of the Macro on the second carrier wave layer and the 4th down-run survey information of each LPN on the second carrier wave layer.Wherein, At the 4th down-run survey signal of per two LPN on the second carrier wave layer is that same UE measures the downstream signal that these two LPN on the second carrier wave layer send respectively, and the Macro on the second carrier wave layer and the 4th down-run survey information any one LPN are that same UE measures with the downstream signal that this LPN sends Macro respectively.

Then; Macro will compare in the 4th down-run survey information of the 4th down-run survey information of the Macro on the second carrier wave layer and each LPN on the second carrier wave layer; If the 4th down-run survey information of the Macro on the second carrier wave layer is all measured thresholding greater than the preset the 4th with the 4th down-run survey information of the LPN that is compared; And the difference of Macro and the 4th down-run survey information LPN that is compared on the second carrier wave layer is less than preset the 4th difference threshold, Macro by state on the second carrier wave layer Macro with the LPN of comparison different cell ID is set.

Macro will compare in the 4th down-run survey information of per two LPN on the second carrier wave layer; If the 4th down-run survey information of these two LPN on the second carrier wave layer is all measured thresholding greater than the 4th; And the difference of the 4th down-run survey information of these two LPN on the second carrier wave layer is less than the 4th difference threshold, and Macro is that two LPN are provided with different cell ID.

The detailed realization of above-mentioned two kinds of execution modes can be repeated no more at this referring to Fig. 5 A and Fig. 5 B.

Present embodiment accomplished the distribution to the cell ID of each LPN under the Macro through mixing the cell ID method of salary distribution equally, reached the purpose that not only can take into account network performance but also can take into account performance of handoffs.

In this explanation, each embodiment of front of the present invention is equally applicable to the scene that not only has identical cell ID but also have different cell ID.Illustrate, suppose that there are 6 LPN down in Macro, is respectively a LPN, the 2nd LPN, the 3rd LPN, the 4th LPN, the 5th LPN and the 6th LPN.The 2nd LPN, the 4th LPN and the 6th LPN are positioned at same interference group, and be with another interference group in a LPN, the 3rd LPN and the 5th LPN have potential strongly disturbing LPN.Suppose that a LPN, the 3rd LPN and the 5th LPN have the cell ID identical with Macro through after the cell ID distribution, the 2nd LPN, the 4th LPN and the 6th LPN have the cell ID different with Macro.Because the 2nd LPN, the 4th LPN have the cell ID different with Macro with the 6th LPN, it can obtain sub-district or regional split gain.For Macro, can use soft quadrature running time-frequency resource; Promptly for the low speed UE that satisfies certain channel quality requirement under the Macro; Perhaps SINR or signal strength signal intensity are higher than the UE (for example center UE) of certain thresholding; The one LPN, the 3rd LPN, the 5th LPN and Macro adopt identical running time-frequency resource to transmit; For example a LPN, the 3rd LPN, the 5th LPN and Macro can use simultaneously among Fig. 2 E eight time of very first time pattern to the pattern wherein any one or its combination transmit, thereby obtain the regional split gain.Be lower than the UE (for example edge UE) of certain thresholding for SINR under the Macro; Macro can use with a LPN, the 3rd LPN, the 5th LPN orthogonal time frequency resources and transmit data; For example, a Macro and a LPN, the 3rd LPN, the 5th LPN use transmitting of different time pattern among Fig. 2 E respectively.In addition,, can between the Macro with identical cell ID and LPN, use identical running time-frequency resource to carry out the transmission of data and control channel, obtain diversity gain, thereby guarantee the reliability of communicating by letter for high speed UE.

Based on above-mentioned; On the first carrier layer or, send specific CRS, PSS, SSS, PDCCH, PCFICH, PHICH, PDSCH, CSI-RS, USRS and the ePDCCH of its coverage cell respectively for LPN with different cell ID or Macro in the scene that can have identical cell ID and different cell ID between each LPN on the second carrier wave layer and the Macro simultaneously.Continuation is an example with a LPN; If a LPN has the cell ID different with other LPN and Macro, then a LPN need send specific CRS, PSS, SSS, PDCCH, PCFICH, PHICH, PDSCH, CSI-RS, USRS and the ePDCCH of a LPN institute coverage cell.

For having the LPN of identical cell ID with Macro, the transmission means of its signal or channel has following several kinds:

First kind of transmission means: Macro all sends identical CRS with LPN, and Macro and LPN all send identical PDCCH, PCFICH, PHICH and PBCH one of them or its combination.With a LPN is example; That is to say; If a LPN has identical cell ID with Macro on the first carrier layer or on the second carrier wave layer; Then a Macro and a LPN all send CRS, PDCCH, PCFICH, PHICH and PBCH one of them or its combination on the first carrier layer, and perhaps a Macro and a LPN all send CRS, PDCCH, PCFICH, PHICH and PBCH one of them or its combination on the second carrier wave layer.

Second kind of transmission means: Macro all sends identical CRS with LPN, and Macro and LPN all send identical PDCCH, PCFICH, PHICH, PBCH and PDSCH one of them or its combination.Wherein, PDSCH is based on the CRS demodulation.With a LPN is example; That is to say; If a LPN has identical cell ID with Macro on the first carrier layer or on the second carrier wave layer, then a Macro and a LPN send CRS, PDCCH, PCFICH, PHICH, PBCH and PDSCH one of them or its combination on the first carrier layer; Perhaps a Macro and a LPN send CRS, PDCCH, PCFICH, PHICH, PBCH and PDSCH on the second carrier wave layer.

The third transmission means: Macro sends CRS, PDCCH and PBCH one of them or its combination, and LPN does not send above-mentioned channel/signal.With a LPN is example; That is to say; If a LPN has identical cell ID with Macro on the first carrier layer or on the second carrier wave layer; Then have only Macro all sending CRS, PDCCH and PBCH one of them or its combination on the first carrier layer or on the second carrier wave layer, a LPN does not send.

The 4th kind of transmission means: Macro and LPN all do not send CRS or PDCCH.With a LPN is example, that is to say, if a LPN has identical cell ID with Macro on the first carrier layer or on the second carrier wave layer, then a Macro and a LPN all do not send CRS or PDCCH.

Further, for above-mentioned four kinds of transmission meanss, Macro with can use the quadrature running time-frequency resource to send USRS and PDSCH on the first carrier layer or on the second carrier wave layer with LPN (a for example LPN) that Macro has an identical cell ID.

In above-mentioned four kinds of transmission meanss; If do not send CRS; Then Macro with can use the quadrature running time-frequency resource sending USRS and PDSCH on the first carrier layer or on the second carrier wave layer, to obtain diversity gain with LPN (a for example LPN) that Macro has an identical cell ID.That is to say, Macro with can use the quadrature running time-frequency resource to send USRS on the first carrier layer or on the second carrier wave layer or on the second carrier wave layer with LPN (a for example LPN) that Macro has an identical cell ID.Perhaps, Macro with can use the quadrature running time-frequency resource to send PDSCH on the first carrier layer or on the second carrier wave layer or on the second carrier wave layer with LPN (a for example LPN) that Macro has an identical cell ID.

In above-mentioned four kinds of transmission meanss; If do not send CRS; Then Macro with can also use identical running time-frequency resource sending USRS and PDSCH on the first carrier layer or on the second carrier wave layer, to obtain the spatial reuse gain with LPN (a for example LPN) that Macro has an identical cell ID.That is to say, Macro with can also use on the first carrier layer or on the second carrier wave layer identical running time-frequency resource to send USRS with LPN (a for example LPN) that Macro has an identical cell ID.Perhaps, Macro with can also use on the first carrier layer or on the second carrier wave layer identical running time-frequency resource to send PDSCH with LPN (a for example LPN) that Macro has an identical cell ID.

Wherein, the USRS of corresponding same UE is identical with PDSCH; The USRS of corresponding different UEs generally is different with PDSCH, and for example the precoding of USRS can be different, and the content that PDSCH carries can be different.But, for Macro with have the LPN of identical cell ID with Macro, the USRS that is sent is identical with PDSCH, if promptly Macro sends USRS and the PDSCH of certain UE, this LPN also can send USRS and the PDSCH of this UE.

Further, the UE to 2 groups of UE abilities can also adopt control channel (ePDCCH) expansion or that strengthen to carry out the control channel transmission.Different with PDCCH is, and ePDCCH can use based on the pilot tone of DMRS carries out demodulation, shares the shared running time-frequency resource position of PDSCH with PDSCH, such as being that granularity is carried out resource allocation with Resource Block to (RB pair).EPDCCH can be the UE service of 2 groups of UE abilities at the first carrier layer or the second carrier wave layer.

For example, if a UE belongs to 2 groups of UE abilities, a LPN sends CRS and PDCCH on the second carrier wave layer, on the first carrier layer, send ePDCCH.

What further, present LPN mainly considered is omnidirectional antenna.The benefit of sectorization is the isolation that can increase between the sector, improves the signal quality in the single sector, increases the reusable resource in space.In order further to obtain spatial gain, can consider LPN is carried out sectorization.For example, LPN is divided into 3 sectors, 6 sectors; Perhaps vertical plane cell splitting or horizontal plane cell splitting, to form the antenna coverage areas more than 2 or 2, wherein, each overlay area has the main beam of oneself to cover.These antenna overlay area is the sector.Macro is after being divided into a plurality of carrier waves on the first carrier layer and the second carrier wave layer, and Macro can also carry out following any sectorization to be handled:

Macro is carrying out the sectorization processing to each LPN in the network on the first carrier layer and/or on the second carrier wave layer.Wherein, because the power ratio of LPN is less, simultaneously LPN is carried out the sector on the first carrier layer and the second carrier wave layer and divide.Wherein, be a kind of optional execution mode to LPN in the sector that marks off equal number on the first carrier layer and on the second carrier wave layer, perhaps, also can mark off the quantity different sector.

Macro handles on Macro first carrier layer, carrying out sectorization.

Macro handles on Macro first carrier layer, carrying out sectorization, and each LPN in the network is being carried out the sectorization processing on the first carrier layer and/or on the second carrier wave layer.

Further, Macro is that cell ID identical or inequality is distributed in the different sectors of each LPN in the network, that is to say to have identical cell ID or different cell ID between these sectors.Fig. 6 A is a kind of sectorization result sketch map that eighth embodiment of the invention provides.Wherein, Macro does not carry out sectorization at the first carrier layer, and each LPN is split into 3 sectors, and each sector has identical cell ID.Fig. 6 B is the another kind of sectorization result sketch map that eighth embodiment of the invention provides.Wherein, Macro is split into 3 sectors at the first carrier layer, and the value lower limit of its power is the power of each LPN, and higher limit is the power of Macro at the second carrier wave layer, and each LPN is split into 3 sectors, and each sector has different cell ID.Fig. 6 C is another sectorization result sketch map that eighth embodiment of the invention provides.Wherein, Macro is split into 6 sectors at the first carrier layer, and each LPN is split into 6 sectors, and all is to have identical or different cell ID in each sector.

Wherein, when sector number during greater than 4, Macro can distribute different cell ID for adjacent sectors, for example realizes that through 2 cell ID are set at least adjacent sectors use the purpose of different cell ID, thereby reduces the interference between the sector.

In addition, in Fig. 6 A-Fig. 6 C, LPN is split into the sector of same number at the first carrier layer and the second carrier wave layer, but is not limited thereto, for example: Macro can with same LPN on the first carrier layer with the sector that on the second carrier wave layer, divides different numbers.

Respectively divide among the result above-mentioned, Macro can disturb to reduce for distributing the quadrature running time-frequency resource between the sector of LPN with identical cell ID.

Further, can relatively have downlink or uplink quality of signals difference between two sectors of LPN of identical cell ID, when its difference was higher than certain thresholding, these two sectors were classified as the resource multiplex collection, otherwise these two sectors are classified as the accurate orthogonal set of resource.Macro is that the LPN of resource multiplex collection uses multiplexing running time-frequency resource, for example all uses a time pattern among Fig. 2 E.For example, if be positioned at a LPN of the second carrier wave layer, the 3rd LPN and the 5th LPN are classified as the resource multiplex collection, use identical time-domain resource between them.In like manner, if be positioned at the 2nd LPN of the second carrier wave layer, the 4th LPN and the 6th LPN are classified as the resource multiplex collection, and they also use identical time-domain resource.Macro can use other time-domain resource.

Further, the sector downlink or uplink channel/signal quality of the accurate orthogonal set of resource is sorted, be lower than the UE of certain value,, between the LPN of the accurate orthogonal set of resource, distribute orthogonal time frequency resources like edge UE for channel quality.Be higher than the UE of certain value for channel quality, between the LPN of the accurate orthogonal set of resource, distribute multiplexing running time-frequency resource.

For the LPN sectorization; Macro can be the CSI-RS configuration of each sector configuration particular sector; Macro obtains the down channel situation of each sector according to the signal quality measured feedback result of CSI-RS; Thereby decision UE adheres to the sector, and this mode both had been applicable to that the second carrier wave layer also was applicable to the LPN or the Macro of first carrier layer.Wherein, the description of the LPN that UE can select to be adhered to the attaching process of each sector referring to UE in Figure 1A-Fig. 1 C illustrated embodiment is not described in detail in this.
