For example, system in combination can relate to the system based on LTE of utilizing non-licensed spectrum as mentioned above.As mentioned above, application wherein can comprise D2D or the honeycomb triage operator of for example network control, wherein major control and configuration, such as the configuration of channel/carrying is carried out by LTE network.In other words, high level operation and configuration are maintained at the smooth transformation between D2D or honeycomb Multiflow communication pattern and normal cellular (LTE) communication pattern with permission under network control, and rudimentary channel access process can be implemented in uncontrolled mode from service (LTE) network viewpoint.This can by allow service network, such as LTE operates in licensed spectrum and D2D or the honeycomb triage operator of network configuration occur in non-licensed spectrum, such as realizing on ISM frequency band.
Yet some problems may occur in comprising the shared this control of channel access, resource distribution and resource (frequency spectrum), this is mainly due to the difference on the usable spectrum of two combinational networks or system type, and thereby the difference in channel access and resource distribution/shared mechanism.
Although distribute/share controlling mechanism for cellular communications networks (such as LTE) with the mode allocated channel access based on scheduling and corresponding resource, the corresponding controlling mechanism that is applicable to local area network (LAN) is different being generally aspect (also referred to as the mechanism of monitoring (LBT) type before conversing) non-scheduled or based on competing substantially.
Thereby when merging two such networks or system, to be suitable for realizing, the mode of requirement of the corresponding controlling mechanism of high-rise cellular communications networks realizes channel access in non-licensed spectrum and corresponding resource is distributed/there is problem while sharing controlling mechanism.Particularly, as normally used in local area network (LAN), sensing and conclude whether channel is busy or can be used for transmission to be inadequate for this combination system only, this combination system is for example for example, for realizing the requirement of cellular-type (LTE) system towards QoS, this system has radio bearer and/or the logic channel of a plurality of configurations between communication equipment, and these communication equipments are in D2D or in honeycomb shunting connects and/or transmits.That is to say, even if cellular carrier judgement is shunted business by corresponding D2D or uplink communication to non-licensed band, one or more UE that operator may still be intended for shunting provides some QoS level.In addition, even if cellular carrier generally provides the D2D of network control in non-licensed band, but may being intended for D2D UE, operator provides some QoS level.
In view of this, how to exist in media access protocol (local area network (LAN)/non-licensed band from local area network (LAN) on) consider the problem of (cellular communications networks/from cellular communications networks) particular characteristics.
Therefore requiring further improvement channel access controls.

Fig. 4 illustrates for illustrating according to the schematic diagram of the relation between gross bit rate and general objective bit rate of example embodiment of the present invention.
In Fig. 4, each logic channel (j=1..4) in the logic channel that is four for number, PRB requires to be shown by the block diagram with thick black line, and for the data volume transmitted or bit rate by the square diagram of grey.White piece arrow indication is according to the target bit rate of PRB, and the indication of black patch arrow distributes data volume or the bit rate of (for example in corresponding MAC PDU, being incorporated to).In view of this, the value of the gross bit rate that indication distributes for transfer of data after resource is distributed can be corresponding to the length sum of the black patch arrow in Fig. 4, and the value of indication general objective bit rate requirement can be corresponding to the length sum of the white piece arrow in Fig. 4.
According to example embodiment of the present invention, contention window size modification (recalculate or upgrade rollback window sizes values) can comprise if indicate the value (may with the number of thresholds of appointment poor) of gross bit rate to be greater than the value of indication general objective bit rate requirement, and if increase the size that the value value that (may with the number of thresholds of appointment poor) be greater than the requirement of indication general objective bit rate of the size indication gross bit rate of contention window reduces contention window.As shown above, can be like this by the threshold value of the ratio of value and appointment being carried out relatively etc. to realize basic evaluation.
In other words, for example, new rollback window value can be calculated, if make the mean value of (in the transmission in the past at predetermined number) gross bit rate in MC PDU generation in the past be greater than the general objective bit rate being configured by service network or its access node/base station, new value should for example, higher than previous (initial) value, if and the mean value of (in the transmission in the past at predetermined number) gross bit rate is equal to or less than the general objective bit rate being configured by service network or its access node/base station in MC PDU generation in the past, new value should be less than previously (for example initial) value.
In addition, the value of renewal should be always higher than minimum value and lower than maximum.According to exemplary embodiment of the present invention, as mentioned above, relevant minimum and maximum can be provided by service network or its access node (being base station in the background of contention window appointment (for example, in conjunction with RRC configuration)).
According to exemplary embodiment of the present invention, contention window size modification, increase/reduce contention window size and can depend on various standards.That is to say, the increase of contention window size or the amount of minimizing can be such as depending on relation between aforementioned indicated value (such as their absolute value, the difference between their ratio and 1 etc. of difference), by (service) network control etc.In addition, the amount that increases or reduce can be set to different, and the amount that increases or reduce can (be imagined standard based on various) and is determined to be in the aspect optimizations such as channel access and/or resource distribution/sharing efficiency.
Fig. 5 illustrates flow chart, this flowchart illustrations according to example embodiment of the present invention can or another example of the process that can be operated by terminal equipment.In Fig. 5, describe the detailed process of the process of above summary.The current size of contention window is represented as rollback window, and the minimal size of contention window is represented as CW_min, and the largest amount of contention window is represented as CW_max.
Because the flow process of describing is like this regarded as self-evident and is intelligible with reference to above explanation, so the descriptions thereof are omitted here.
According to exemplary embodiment of the present invention, contention window is assigned can be based on by the logic channel accessing in non-licensed band with by the quality of service requirement of at least one in the data of transmitting on this logic channel.In such contention window is assigned, (initially) of contention window big or small and assign alternatively the minimum of contention window and/or the value of largest amount to be assigned according to qos parameter.This contention window based on QoS is assigned and can be set up and correspondingly be used in the channel access based on competition by one or more equipment (terminal) by service network or its access node/base station.
Fig. 6 illustrates flow chart, this flow process diagram according to exemplary embodiment of the present invention can or the example of the process that can be operated by network entity.Network entity can be the service access node of cellular communications networks or base station, such as the eNB in Fig. 1.
As shown in Figure 6, according to the method for exemplary embodiment of the present invention, can comprise following operation: the qos requirement by the qos requirement mapping (610) of the first radio access technologies (RAT-1) to the second radio access technologies (RAT-2); The qos requirement of the second radio access technologies (RAT-2) based on shone upon is set up (620) contention window and is assigned; And to one or more equipment, provide the contention window that (630) are set up to assign, this contention window is assigned the big or small appointment at least comprising for the contention window of the channel access based on competition.
According to exemplary embodiment of the present invention, the first radio access technologies (RAT-1) can relate to cellular communications networks, be service network, such as LTE, and the second radio access technologies (RAT-2) can relate to local area network (LAN), such as WLAN.Thereby by the logic channel by equipment (terminal) access with can be used for distributing can be relevant with the second radio access technologies (RAT-2) by the resource of the data of transmitting on logic channel, and the channel access based on competition can be carried out the second radio access technologies (RAT-2) is upper.
According to exemplary embodiment of the present invention, as above summary, the service network of RAT-1 can configure the contention window value of RAT-2 so that the QoS that is incorporated to RAT-1 for RAT-2 controls.Even if can realize thus cellular carrier determines to shunt business by corresponding D2D or uplink communication to non-licensed band, still can provide certain QoS level for one or more UE of shunting, even and cellular carrier generally provides the D2D of network control in non-licensed band, still can provide certain QoS level for D2D UE.
In this regard, qos requirement mapping as shown above can be carried out in service network or its access node/base station, is translated into one or more corresponding qos requirement of RAT-2 by one or more relevant qos requirement of this mapping RAT-1.Such mapping or translate can be based between different RAT the mapping of QoS kind, this RAT can be that operator is specific.Thus, operator can be configured for particular value that contention window assigns and therefore according to it between different RAT, be the QoS in the preferred QoS kind mapping configuration RAT-2 between RAT-1 and RAT-2.
As example, can consider the situation of the WLAN shunting that honeycomb is controlled, wherein Virtual network operator is wanted to non-licensed band shunting business and is provided QoS and fairness to the equipment of shunting.As mentioned above, under these circumstances, network can have WLAN-AP with the equipment of being shunted of the uplink communication of WLAN AP based on execution and cover, or the equipment of shunting can connect in direct D2D.
Conventionally the different QoS for operating in cellular communication pattern having by cellular network configuration due to honeycomb UE configures, so Virtual network operator may want also to reflect these QoS configurations in WLAN shunting situation.For this reason, operator can control shunting QoS by the WLAN station for corresponding shunting (i.e. the UE of shunting) configuration contention window parameter value via access node or the base station of cellular network.For example operator can shunt from the business of UE1 and UE2 and come configuration UE 1 and UE2(to be attached to the WLAN AP of operator by the corresponding competition of transmission (rollback) window configuration messages), this competition (rollback) window configuration messages comprises suitable contention window appointment, and this contention window assigns one of reaction UE in cellular communication pattern, to have respectively higher priority data and/or higher QoS/ service class.Such message can for example send via RRC signaling.
Cellular network can arrange by the parameter of assigning for contention window different value and be controlled at the QoS balance between WLAN station (i.e. the UE of shunting), the parameter that contention window is assigned i.e. initial size/when front window size at least, and be that min window size and maximal window are big or small alternatively.Thereby by configuration contention window (rollback) parameter, cellular carrier/network can be configured in the relative QoS between shunting device according to service needed, available resources and/or operator's preference etc.
According to exemplary embodiment of the present invention, can in the background of aforementioned channels access mechanism, provide Conflicts management strategy.In access mechanism based on competition, the conflict of (because the conflict between the various users of transmitting in same asset causes) can be detected and solve thus.
Fig. 7 illustrates according to the signaling diagram of the example process of exemplary embodiment of the present invention.In the example of Fig. 7, D2D communication is communicated by letter these two kinds of afore-mentioned by generally consideration is as follows with up WLAN.
In both cases, the UE of equipment (terminal) equipment #1, for example shunting can detect the conflict in the channel access based on competition.Such conflict may cause in following situation, and wherein determine that the large young pathbreaker of contention window the is reduced result of the process of Fig. 3 or 5 (for example as) and the size that increases contention window will be necessary intuitively aspect the conflict of resource or race condition.Additionally or alternatively, such conflict may cause in following situation, and wherein the data of the distribution of predetermined quantity are dropped.
For example, the in the situation that of conflict, according to the process of exemplary embodiment of the present invention, may want to reduce contention window size, because the average summation of logical channel bit rate will reduce due to conflict, and a kind of typical way of processing such situation in the access mechanism based on competition will be that to increase contention window big or small.
When such conflict being detected, equipment (terminal) equipment #1 can report conflict, the i.e. corresponding report of transmission detecting.In the situation that D2D communicates by letter, the recipient of such report can be the access node/base station eNB of another equipment (terminal) equipment # 2 and/or cellular network, or the recipient of such report in the situation that of up WLAN communication can be the access node/base station eNB of cellular network.Can when detecting or at the predetermined timer that recovers, after the period, carry out conflict report.
When receiving conflict report from equipment #1, recipient (equipment # 2 and/or eNB) can the adaptive contention window of conflict based on report assign as conflict solution.If recipient is equipment # 2, it can local use that adaptive contention window is assigned, i.e. application collision solution in the follow-up channel access based on competition.If recipient is eNB, it can send adaptive contention window to equipment #1 and assign the instruction of conduct conflict solution.
When receiving solution instruction, equipment #1 can be used that adaptive contention window is assigned, i.e. application collision solution in the follow-up channel access based on competition.
In view of aforementioned Conflicts management strategy, can overcome from the possible problem due to the conflict of other users in same asset, this problem may increase or failed decoding trial and occurring suddenly as disturbing.In this regard, timer (recovery _ timer) can by use to allow for certain time period with for can meet for configuration the PRB that D2D logic channel configured and the Backoff window value of needs is compared too high Backoff window value (being contention window size).Excessive sizes values like this may be owing to the following fact, and this fact is for to attempt to reduce rollback window value according to the process of exemplary embodiment of the present invention, but due to the potentially conflicting due to too congested resource, in fact this value should be increased.It also may be owing to the following fact, and this fact is dropped at MAC layer for for example abandon PDU(PDU when reaching maximum retransmit number of certain quantity when the PDU number that is considered as sending with success is proportional).When conflict being detected (for example, when recovering timer passage), trigger signaling procedure with this problem about detecting/conflict contact eNB.For the conflict between equipment, solve, equipment can be to other nearby users broadcast management messages, and the equipment that receives this message can be taked suitable action, such as their rollback window value being reset to initial value and/or the value of minimum and maximal window value for example being changed to the quantity (wherein this value can be for just or negative, and can be proposed by network settings or the equipment in local area network (LAN)) of window _ deviant.
In view of above, according to exemplary embodiment of the present invention, can allow in some times contention window too large (aspect aforesaid indicated value), therefore at equipment, contact eNB for example for before redistributing radio resource, with the transmission bit rate target comparison that should have according to the logical channel bit rate of configuration, sacrificed the transmission bit rate target of oneself.In other words, aforementioned recovery timer attempts to be equilibrated at performance loss in the connection in non-licensed band and in the equipment participating in and the signaling effort between eNB/ network.
With reference to above, according to exemplary embodiment of the present invention, for the contention window of the Channel Access Mechanism (this Channel Access Mechanism for example can be developed, for honeycomb (LTE) radio stack) based on competition, assign, in particular for the size of contention window, can be derived.This for example the MAC PDU based on in the past generate in mean value and the requirement of general objective bit rate of gross bit rate of (in the transmission in the past of predetermined number), it is prioritization bit rate (PRB) sum of each D2D logical channel assignment by network that this general objective bit rate requires independently to be calculated conduct by two equipment.
With reference to above, according to exemplary embodiment of the present invention, resource-sharing between communication equipment can be towards appropriate balance, for example, by the desired balance of qos parameter of the configuration of indivedual equipment, automatically adjust, the cut-in method of this communication equipment utilization based on CSMA, but in MAC PDU generates, utilize logic channel multiplexing (for example, according to LTE).
