Description
Technical field
The present invention relates to the resource allocation techniques in the GSM, especially disposed wireless resource allocation methods and device thereof in the multicarrier system of high-speed packet access signal channel.
Background technology
In order to improve the transmitting uplink data ability; FDD (FDD in the WCDMA access system (WCDMA); Frequency Division Duplex) pattern and time division duplex (HCR TDD, High ChipRate Time Division Duplex) pattern also has TD-SCDMA system (TD-SCDMA; Be called low spreading rate tdd mode again; LCR TDD) in the Release6 of 3G (Third Generation) Moblie standardization body definition and Release7, introduces up enhancing (EnhancedUplink) technology in succession, be called HSUPA (High Speed Uplink Packet Access, high speed uplink packet access) technology.
The key technology of HSUPA comprises HARQ (Hybrid Automatic Repeat Request, mixed automatic retransmission request), AMC (Adaptive Modulation and Code, Adaptive Modulation and Coding) and fast dispatch.Base station node B time slot scheduling, code channel and power resource; Power resource has retrained the contribution of terminal to system interference; Keep whole system through scheduling and disturb on certain level, promptly keep RoT (Rise-over-Thermal, background noise promotes) to be stabilized in the threshold value; AMC is selected to realize through E-TFC (E-DCH Transport Format Combination, E-DCH TFS Transport Format Set) in the terminal in the restriction of Node B scheduled resources; In transmission course, after data were sent at the terminal, Node B fed back according to the correctness that receives fast, and the terminal is retransmission data or transmission new data according to result's decision of feedback, promoted transmission performance thereby can utilize the merging of HARQ to gain; Being used in combination of fast dispatch, these three kinds of technology of AMC and HARQ can make the variation of transfer of data fast adaptation channel, thereby reduce retransmission delay time, improves link performance, the elevator system throughput.

In the single carrier ascending packet data process of Release7 standard, at first carry out the Traffic Channel of HSUPA and the foundation of control channel, to scheduling and non-scheduled transmission allocation of channel resources may.When the terminal is inserted, obtain the Traffic Channel at this terminal and the resource information of uplink/downlink control channel from network side; In the data dispatch transmission course; Network side is according to the CRC check information that received measurement of E-PUCH quality of channel and reception data last time or initially according to E-RUCCH (E-DCH Random Access Uplink ControlChannel; E-DCH inserts ascending control channel at random) SI (the Scheduling Information that reports; Schedule information) information is sent the necessary control information that the user can send grouped data through the E-AGCH channel dispatch, comprises power, time slot, code channel etc.; UE is after receiving the E-AGCH schedule information; Carry out E-TFC (E-DCH Transport Format Combination, E-DCH TFS Transport Format Set) according to scheduling grant and select, send grouped data through the E-PUCH channel then; The ACK/NACK of Node B feedback data on E-HICH (Acknowledgement/Negative ACKnowledgement, ack/nack is replied).Non-scheduled transmission is in the resource of network reservation and transmit in the time, and Node B feeds back to the terminal according to the correctness of the data of the E-PUCH channel that receives on the E-HICH channel.
When the single carrier HSUPA of the current agreement of Release7 ascending packet data transmits; Because Traffic Channel and control channel are all on a carrier wave; The resource that particularly can be used in HSUPA when this carrier wave has in limited time very much, the peak rate that adopts the HSUPA technology to send data will be subject to code channel number what.Obviously; In order further to improve transmission rate; Adopt multi-carrier mode expansion HSUPA technology to become a kind of inevitable choice; When adopting multi-carrier mode, how to optimize the resource utilization of multicarrier system, resource allocation how to carry out multicarrier effectively becomes the problem that must solve.

Embodiment
Core of the present invention is to provide a kind of base station of supporting multicarrier work; Each carrier wave wherein can be according to the high speed ascending grouped access channel of the network planning or business demand configuration some; When the terminal uses high speed ascending grouped access channel to carry out transfer of data, according to the base station interference on each carrier wave is measured, utilize the interference metric values that obtains that each carrier wave is sorted; When resource allocation; Preferentially distributing radio resource on the less carrier wave of interference metric values when Resources allocation, is confirmed concrete resource distribution mode in conjunction with the configuring condition of high-speed downlink packet access channel on the carrier wave simultaneously.
In order to make those skilled in the art person understand the present invention program better, the present invention is done further detailed description below in conjunction with accompanying drawing and execution mode.
Embodiment of the present invention is that example is launched explanation with the TD-SCDMA system.TD-SCDMA is a kind of system of time division duplex, and the resource of uplink and downlink is distinguished through different time slots on same carrier wave.But principle of the present invention is not limited to the TD-SCDMA system, also goes for adopting the WCDMA system and the CDMA2000 system of multi-transceiver technology.After introducing the HSUPA technology, for the multi-carrier TD-SCDMA base station, can be in the network planning stage or at the business demand configuration high-speed ascending grouped access channel of the enforcement of the network sub-district of serving according to the base station in service.Generally speaking, for M the carrier wave that the base station is supported, can select wherein N carrier wave and at each carrier wave configuration high-speed ascending grouped access channel, N can also can equal M less than M.Dispose the carrier wave of high speed ascending grouped access channel, promptly be called the HSUPA pattern of supporting.In addition; Operator can also be as required on sub-district one-level or different carrier wave, considers whether to support the strategy of HSDPA pattern, like this; Several kinds of different application models may appear on the different carrier waves; Wherein relevant with HSUPA technology is, disposes high speed ascending grouped access channel and high-speed downlink packet access channel on the carrier wave simultaneously, and this application mode is called this carrier wave and supports HSUPA and HSDPA technological simultaneously; Or support HSPA+ technological; Its discrepancy only is that channel architecture is slightly different, and a kind of in addition application model is but that carrier wave disposes high speed ascending grouped access channel configuration high-speed downlink grouped access channel not, and this application mode is called this carrier wave and only supports the HSUPA technology.
When carrier wave is only supported the HSUPA technology; In the process that the sub-district is set up, need in the resource pool of the up direction of this carrier wave and down direction, one group of dedicated channel be set respectively; It is the DCH channel; Be used for transmission terminal and internetwork high-rise control signaling, high-rise response message etc., this dedicated channel is called follows channel, when terminal originating service request and must be the channel of following of a pair of like this up-downgoing of terminal distribution simultaneously more also when being assigned with high speed ascending grouped access channel.Owing to follow channel in the whole process of terminal use communication service, all to be assigned with use; Can reach Synchronization Control and power control effect preferably; Therefore; When the terminal in scheduling process, if when the scheduling interval of high speed ascending grouped access channel E-PUCH is big, the Synchronization Control of up E-PUCH channel can be with reference to following channel to carry out.User terminal follows channel to obtain the high-level signaling of network side transmission and the power and the Synchronization Control data of uplink/downlink control channel through up-downgoing; So that user terminal can correctly be set the initial power of the uplink/downlink control channel that is selected and carry out Synchronization Control, and then makes user terminal and network side communicate through the uplink/downlink control channel that is selected.
When carrier wave is supported HSUPA and HSDPA technology simultaneously; Or support HSPA+ technological; In the process that the sub-district is set up, then need not be provided with and follow channel, under this scene; The terminal use in the whole process of communication service and the transmission of the high-level signaling between the network then through SRB (Signaling Radio Bearer; Signaling Radio Bearer) be mapped in respectively on descending HS-DSCH transmission channel and the up E-DCH transmission channel, form a loop by E-DCH and HS-DSCH transmission channel like this and transmit high-rise SRB information, these two transmission channels are mapped to respectively on HS-PDSCH physical channel and the E-PUCH physical channel again and transmit.Owing to there has not been the channel of following, thereby improved the resource utilization of system, but dispatched and during resource allocation, need be through setting the demand that suitable scheduling interval satisfies power control and Synchronization Control.
Further; Set up in the process at channel; Each sub-district also need be divided into two groups in the resource that on each carrier wave all can be used for high speed ascending grouped access channel: the E-PUCH channel in scheduling transmission resources pond and the corresponding control channel E-AGCH, the E-HICH that in the down direction resource, dispose, collocated E-HICH channel in the E-PUCH channel in non-scheduled transmission reserved resource pond and the corresponding down direction resource.
When the terminal was initiated to be suitable for adopting the service request of HSUPA technical transmission and is allowed to, network side was that user terminal distributes: the frequency that E-AGCH, E-HICH channel group, the ability rating support that the employed E-PUCH/E-HICH channel of non-scheduled transmission, scheduled transmission need UE to keep watch on need detect according to the ability rating at terminal.Dispatch constantly at each, the network based last CRC check of data and the channel quality of measurement of receiving in conjunction with the schedule information SI at terminal, given the E-DCH channel of this user terminal use according to the dispatching algorithm allocation of channel resources may.The channel resource of same user terminal is distributed on the carrier wave as much as possible, when only resource can't satisfy the demands on a carrier wave, is this user terminal with the E-DCH resource allocation on other carrier waves again.
As shown in Figure 1, practical implementation step of the present invention comprises:
Step 101: confirm the ascending wireless resource quantity that to use at the terminal.
It is terminal distribution non-scheduling resource or the scheduling resource pond that need monitor for terminal distribution that method of the present invention can be applied to radio network controller; At this moment; This function is performed in radio network controller; Also can be used for being the terminal distribution scheduling resource constantly in each scheduling, at this moment, this function is carried out by the base station.
Non-scheduling resource can guarantee for the terminal provides fixing communication bandwidth and QoS; Generally be used for the more intense business of carrier signaling and real-time; Like mandarin sound business and VoIP voice service etc., non-scheduling resource distributed in the starting stage that terminal and network establish a communications link, and in the process that whole communication service takes place, did not generally adjust; But when needs are adjusted, also can change the resource of non-scheduled transmission through the signaling reprovision.When distributing non-scheduling resource, the ascending wireless resource quantity that the terminal need be used knows according to its type of service in advance.
For the scheduling resource pond that need monitor for terminal distribution, this ascending wireless resource quantity is ready-portioned in advance for each carrier wave in sub-district foundation and channel configuration process.The terminal only needs the scheduling grant information on the monitoring E-AGCH control channel in communication process, can obtain to use the E-PUCH channel information.
In the HSUPA technology; Real-time scheduling feature is accomplished in the base station; Dispatching algorithm in the base station is responsible for needing scheduled terminals in each TTI (Transmit Time Interval, Transmission Time Interval) selection, and confirms that scheduling this time needs the ascending wireless resource quantity of using; When confirming resource requirement quantity, need obtain terminal to report and give the traffic information to be transmitted of base station; In addition, also need confirm suitable coded modulation grade etc., just can obtain the quantity required of Radio Resource then according to channel condition.
Step 102: each the carrier-in-interference metric according to being configured high speed ascending grouped access channel in advance is the terminal distribution ascending wireless resource.
In order to optimize the use of each carrier frequency resources preferably, the present invention's proposition need be measured the channel condition of each carrier wave, obtains the interference metric values of each carrier wave.With three carrier systems is example, and the interference of the carrier wave A that supposes to measure, B, C is respectively L
A, L
BAnd L
C, for the multi-carrier HSUPA system, owing to adopted a plurality of carrier channels; It is bigger that the channel condition of each carrier wave might differ, and for carrier wave A, the load on this carrier frequency of adjacent sub-district is heavier; Therefore bigger to the interference of this cell carrier A, can badly influence the efficiency of transmission of system.Suppose the following relation of interference existence according to three carrier waves of metrical information acquisition
L
C≥L
B≥L
A，
The interference that is carrier wave C is maximum, and the interference of carrier wave A is minimum.This moment should be as far as possible with resource allocation on carrier wave A, when only the Radio Resource on carrier wave A can not satisfy the demand at terminal, just further on carrier wave B Resources allocation with satisfied to remaining traffic transmission demand.
Because the Radio Resource of TD-SCDMA system is divided by time slot; When specifically how to implement the interferometry on each carrier wave; Can measure respectively and carry out average treatment each time slot, also can take the interference measure on a plurality of time periods is averaged processing.Simultaneously, when resource allocation, need consider that also that disturbs on each time slot that causes to avoid resource allocation is unbalanced in each different time-gap of same carrier wave Resources allocation as far as possible equably.That is, sort to each carrier wave that is configured high speed ascending grouped access channel according to interference metric values in the base station, and preferentially to select the little carrier wave of interference metric values be the terminal distribution ascending wireless resource.
In the practical implementation of this step; Need to confirm to be allocated on each carrier wave the resource quantity of high speed ascending grouped access channel, and be the terminal distribution ascending wireless resource according to the ascending wireless resource quantity that the high speed ascending grouped access channel resource quantity on each carrier wave and terminal needs use.
For example three of the sub-district carrier waves are distinguished called after carrier wave A, B, C, and the total resources that each carrier wave can be used for the uplink direction are respectively T
A, T
B, T
CFor the E-DCH channel resource allocation of multicarrier, the resource of three carrier waves is used as an integral body considers, the unified allotment.Network terminal is utilizing situation, load, interference and being situation such as handoff reservation resource decision HSUPA available volume of resources according to present Internet resources at first:
If the resource of up direction common signal channel and handoff reservation channel occupancy is respectively F
A, F
B, F
C
For carrier wave or the sub-district of only supporting HSUPA technology, establishing up direction, to follow the resource of channel occupancy be G
A, G
B, G
C
For supporting HSUPA and HSDPA technology simultaneously; Or the carrier wave or the sub-district of support HSPA+ technology; The loop of forming through HS-DSCH and E-DCH transmits high-rise SRB, and then cancellation follows the use of channel, is that the shared resource of DCCH of HSDPA is H at up direction at this moment
A, H
B, H
C
According to whether having disposed HSDPA, calculate the up-high speed grouped access channel resource that each carrier wave can be used, computational methods deduct common signal channel, handoff reservation channel, follow residual resource after channel or the HSDPA DCCH resource for the total resources of each carrier wave.With carrier wave A is example, if only support the HSUPA technology, then maximum available radio resources quantity is U
A=T
A-F

AIf support HSUPA and HSDPA technology simultaneously, or support the HSPA+ technology that then maximum available radio resources quantity is U
A=T

B, U
C, during according to the network planning to the conditions of demand of the up intervention channel resource of high-speed packet, from U
A, U
B, U
CIn obtain the channel resource that carrier wave A, B, C can be used for uplink and be respectively R
A, R
BAnd R
C
Follow the occasion of channel for not using up-downgoing; Dispose high-speed downlink packet access channel on the carrier wave at the ascending wireless resource place that the terminal is assigned with; This moment is owing to high-level signaling transmission of Information between terminal and the network also need take certain high speed ascending grouped access channel resource; Therefore; When confirming the ascending wireless resource quantity that the terminal need be used, also need increase the ascending wireless resource that is used for high-level signaling information between up direction transmission terminal and the network, and will be used for the high-speed downlink packet access channel of high-level signaling information between down direction transmission terminal and the network for terminal distribution.
If scheduled transmission and non-scheduled transmission are supported the multiplexing and physical resource merging of the MAC layer at base station and terminal; The E-PUCH resource of the scheduled transmission E-PUCH resource of distributing and non-scheduling distribution independent allocation separately so can be also can be on different carrier on the same carrier wave.When transfer of data, can carry out resource merges.If scheduled transmission and non-scheduled transmission do not support that the MAC layer at base station and terminal is multiplexing and merge with physical resource, the scheduled transmission E-PUCH resource of the distributing E-PUCH resource avoiding distributing with non-scheduling is on same carrier wave so.
Whether scheduled transmission and non-scheduled transmission support the multiplexing characteristic that merges with physical resource of the MAC layer at base station and terminal means when carrying out resource allocation whether need resource allocation be carried out in these two resource pool unifications.Therefore; When scheduled transmission and non-scheduled transmission do not support that the MAC layer at base station and terminal is multiplexing; In the allocation schedule resource time; If existed for the up non-scheduling resource of this terminal distribution on the carrier wave, then with the scheduling resource quantity on this carrier wave as the resource quantity that can be allocated for high speed ascending grouped access channel.This moment, non-scheduling transmission resources carried out constantly not having data to be carried in corresponding scheduling, can not be used to the transmitting and scheduling business datum, and like this, the resource utilization of system can not be improved, but can reduce the complexity of system.And if scheduled transmission and non-scheduled transmission support that the MAC layer at base station and terminal is multiplexing; When the allocation schedule resource; If existed for the up non-scheduling resource of this terminal distribution on the carrier wave; In the step of confirming the ascending wireless resource quantity that the terminal need be used, the up non-scheduling resource that also need deduct on this carrier wave transmits the remaining resource quantity of non-data dispatching.At this moment, the resource of system can be fully utilized, but the complexity that realizes is higher.
Accompanying drawing 2 has provided that the base station is the concrete flowchart of terminal distribution resource in the three carrier wave HSUPA systems.Whether the available reverse link traffic channel resource of at first judging carrier wave A according to the scheduling buffer memory that calculates is less than the required resource (step 202) of uplink scheduling transport service channel; If the available reverse link traffic channel resource of carrier wave A more than or equal to the required channel resource of uplink scheduling transport service channel, then is a reverse link traffic channel resource allocation resource requirement (step 204); If the resource of carrier wave A is less than the required resource of uplink scheduling transport service channel; Can the available reverse link traffic channel resource of carrier wave A all be distributed to uplink scheduling transport service channel (step 203); Further whether there is non-scheduling transmission resources and whether allows to dispatch and judge whether the available reverse link traffic channel resource of carrier wave A and carrier wave B satisfies the requirement (step 205) of uplink scheduling transport service channel with non-scheduled resources is multiplexing according to carrier wave B; If satisfy, then give E-DCH channel (step 206) with the resource allocation of carrier wave B; Otherwise; When the resource of carrier wave B still can't satisfy the demand of dispatch E-DCH channel; Except that the whole available ascending resource of carrier wave B is distributed to (step 207) the reverse link traffic channel, whether have non-scheduling transmission resources according to carrier wave C again and whether allow to dispatch to be used for dispatch E-DCH channel (step 208) with the multiplexing resource of non-scheduled resources with carrier wave C.
