Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of cooperative multipoint transmission dispatching method and device.
Background technology
At present radio spectrum resources growing tension, LTE(long term evolution, Long Term Evolution) network need to adopt the mode of identical networking to improve system spectrum utilance.Although identical networking is the availability of frequency spectrum of elevator system effectively, identical networking mode has been brought more serious presence of intercell interference, and Cell Edge User, owing to being subject to the interference of multiple neighbor cell signals, has a strong impact on transmission quality and throughput of system.
Disturb the adjacent area that covers edge customer in order to reduce community, and LTE system has been introduced CoMP(coordinated-multiple-point, coordinate multipoint) transmission technology.CoMP transmission technology is the cooperation between the multiple transfer points (transmission point, TP) that separate on geographical position.As edge UE(user equipment, subscriber equipment, also claim terminal) when the overlapping fringe region in Liang community, main plot and cooperation cell send out downlink data or receive upstream data on identical running time-frequency resource this UE simultaneously, signal from multiple transfer points aloft superposes, and receiving end signal is strengthened, and interference source reduces simultaneously, interference dies down, thereby improves the performance of edge customer.
CoMP transmission technology can be divided into down collaboration transmission and uply combine reception (joint reception, JR).Down collaboration transmission is mainly divided into again two kinds of transmission plans: CS/CB(coordinated scheduling/coordinated beam forming, cooperative scheduling/cooperative beam figuration) and JP(joint processing, Combined Treatment).JP scheme can be divided into again JT(joint transmission, joint transmission) and DPS(dynamic point selection, dynamic transmission point selection) transmission.In JT, multiple transfer points send useful signal to same UE simultaneously, thereby have strengthened the reception signal of UE.
Current CoMP transmission technology, in descending scheduling process, conventionally adopts running time-frequency resource more intuitively to stagger and adopts the scheduling mode of poll.Specific implementation process is as follows:
Step 1: while determining current scheduling, be carved with CoMP user's main plot sequence number, can by the scheme of poll determine this moment actually which community as main plot;
Step 2: select cooperation cell by certain mode, as selected and main plot RSRP(reference signal receiving power, Reference Signal Received Power) community of difference minimum is as cooperation cell, now only between main plot-cooperation cell, dispatch CoMP user, other community normal consistencies, are all used as all users as non-CoMP user and dispatch;
Step 3:1 main plot according to scheduling result by TBS(transport block set, transport block set) and scheduling PRB(physical resource block, Physical Resource Block) resource information, MCS(modulation and coding scheme, modulation and coding strategy) information and user data and/or parameter send to cooperation cell, and cooperation cell completes as indicated cooperation and sends.
Current implementation is mainly deposited shortcoming both ways: Yi Shidang community number is many, edge customer is when many, running time-frequency resource staggers, and to make same running time-frequency resource can only be CoMP user service to scheduling mode, there will be a lot of edge customers slowly to can not get cooperation transmission, now the performance of most edge customers is difficult to be improved; The 2nd, adopt the mode of poll to determine the sequence number of main plot, although can ensure the fairness of each community, can not ensure the performance gain of whole cell cooperative set edge customer throughput, can not carry out CoMP transmission for optimal community.

Embodiment
The embodiment of the present invention has proposed a kind of cooperative multipoint transmission scheduling scheme mainly for CoMP technology, adopt the scheme of sequence to select the community of cooperative gain maximum to be used as main plot, can form the right relation of multiple cooperations simultaneously, compared with prior art, can lose under identical volume situation at community average throughput, effectively promote the throughput of Cell Edge User.
The embodiment of the present invention is applicable to LTE system or LTE-A(long term evolution-advance, and Long Term Evolution strengthens) system and follow-up evolution system, and can be applicable to up JR scheme or the descending JT scheme of these systems.
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, it is the configuration diagram of the applicable system of the embodiment of the present invention.In this system architecture, CCN(central coordination node, center cooperative node) receive multiple transfer points (transmission point as main controlled node, TP) cooperation cell reporting is to relevant information, according to cooperation cell, relevant information is carried out to the distribution of CoMP transfer resource, and cooperation cell is sent to the main plot of cooperation cell centering to the configuration information of relevant information and the CoMP transfer resource that distributes, so that CoMP transmitting and scheduling is carried out in main plot.Here " transfer point " refers to the base station of community or community, multiple long distance wireless heads (remote radio head, RRH) of the base station of Huo Yige community or community and its control.
Based on said system framework, the cooperative multipoint transmission scheduling flow that the embodiment of the present invention provides can as shown in Figure 2, mainly comprise the following steps 21～24:
Step 21:CCN reception CoMP set Nei community reports the right right transmission performance information of cell combination information and cooperation cell in cooperation cell of Zhe community.
Wherein, the cooperation cell of Yi Ge community is to referring to that Yi Zhe community is two cell combination that main plot, adjacent cell are cooperation cell, " the cell combination information that cooperation cell is right " refers to the cell identity information of main plot and the cooperation cell of cooperation cell centering, and cell identity information can be the information that community ID etc. can distinguish different districts.In embodiments of the present invention, agreement use (community m, community n) represents cooperation cell pair, its small area m and community n represent respectively different communities, and the community coming is above main plot, community is thereafter cooperation cell.Such as, the cooperation cell centering that community a reports comprise (community a, b), its small area a is main plot in community, community b is the cooperation cell of community a; The cooperation cell centering that community b reports comprise (community b, a), its small area b is main plot in community, community a is the cooperation cell of community b.
Preferably, the right quantity in cooperation cell that Yi Ge community reports can be one or more, and this quantity can set in advance.By in advance this quantity rationally being arranged to (such as arranging based on experience value), can make CCN in the time that the information reporting based on CoMP set Nei community is carried out transmitting and scheduling, ensure the transfer of data of Cell Edge User as far as possible, thereby improve the throughput of Cell Edge User.
The right transmission performance information in cooperation cell can comprise any one or more parameters that can show the main plot of cooperation cell centering and the transmission performance of cooperation cell, by the right one or more like this parameters in each cooperation cell, can weigh out which or which cooperation cell and carry out cooperation transmission to more needing to form CoMP transmission set.Preferably, right transmission performance information in cooperation cell at least comprises average spectral efficiency (ase) value and the average RSRP value of edge UE.Current each UE can report the RSRP value of adjacent cell, make the RSRP value of RSRP value-this community of delta=adjacent cell, for instance, the delta value of the user in Jiang community 1 and in 2 edges, community is added and obtains the average RSRP value of cooperation cell to (community 1, community 2).Average spectral efficiency (ase) is the spectral efficiency values that the MCS of these UE is corresponding.
Further, each community also can obtain the CoMP factor divided by the average spectral efficiency (ase) value of described edge UE by described average RSRP value, transmission performance information reporting right as cooperation cell the CoMP factor, to CCN, also can be reduced to the computing expense of CCN to reduce the data volume of information reporting.The value of the CoMP factor of a cooperation cell is larger, shows that this cooperation cell carries out cooperation transmission to more forming CoMP transmission set, corresponding, and the right cooperation transmission priority of resource allocation in this cooperation cell is higher.
In the CoMP technology of LTE or LTE-A system, CoMP set can be pre-configured by system, wherein comprised the identification information that can adopt the community of CoMP technology.ENB(evovled NodeB, enode b, i.e. base station) can configure to UE comprising the measurement configuration information of CoMP in being integrated into, UE carries out cell measurement reporting measurement result to its service eNB based on measurement configuration information.In the embodiment of the present invention, the measurement result that CoMP set Nei community reports according to the UE in its coverage, one or more cooperation cell of determining this community to and the right transmission performance information in each cooperation cell, the eNB that then these information exchanges is crossed to place reports CCN.
Such as, eNB community a receives the measurement result for community b that the UE in its coverage reports, according to this measurement result will (community a, community b) as cooperation cell to (its small area a is main plot, community b is cooperation cell), report CCN by this eNB.
Step 22:CCN is according to right cell combination information and the transmission performance information in cooperation cell receiving, division obtains the first cooperation cell pair set and the second cooperation cell pair set, cooperation cell in described the first cooperation cell pair set is to there being two-way cooperation relation, and the cooperation cell in described the second cooperation cell pair set is to only existing unidirectional cooperation relation.
Step 23:CCN is respectively cooperation cell in the first cooperation cell pair set and the second cooperation cell pair set to distributing CoMP transfer resource.
Wherein, the priority of resource allocation of the first cooperation cell pair set is higher than the priority of resource allocation of the second cooperation cell pair set, accordingly, CCN is preferably cooperation cell in the first cooperation cell pair set to distributing CoMP transfer resource, if the cooperation cell in the first cooperation cell pair set remains in addition CoMP transfer resource after distributing CoMP transfer resource, residue CoMP transfer resource is distributed to the cooperation cell pair in the second cooperation cell pair set.
Step 24:CCN is by combined information right cooperation cell and be cooperation cell to the configuration information of the CoMP transfer resource distributing (as PRB resource information, PRB is that the English of physical resource block is called for short, be Physical Resource Block), send to the main plot of cooperation cell centering, so that CoMP transmitting and scheduling is carried out in main plot.Alternatively, CCN can issue respectively all communities in CoMP set by main plot right each cooperation cell and cooperation cell information.The embodiment of the present invention does not limit the specific implementation process of step 24, can realize with reference to existing technology.
Taking community a as example, community a receive the right combined information in cooperation cell that CCN sends (Dui Yi community, this cooperation cell a be main plot, taking community b as cooperation cell) and as this cooperation cell to after the PRB resource information of distributing, carry out CoMP transmitting and scheduling, and according to scheduling result, TBS, PRB resource information, MCS information and user data/parameter being sent to community b, community b carries out cooperation transmission according to these information that receive.
Can find out by above flow process, center cooperative node reports the right right transmission performance information of cell combination information and cooperation cell in cooperation cell of Zhe community according to CoMP set Nei community, microzonation in CoMP set is divided into for depositing and has the first cooperation cell pair set of two-way cooperation relation and for depositing the second cooperation cell pair set that only has unidirectional cooperation relation, and be preferably cooperation cell in the first cooperation cell pair set to distributing CoMP transfer resource.Owing to existing the cooperation cell of two-way cooperation relation to contrast unidirectional cooperation cell to more needing to carry out cooperation transmission, therefore be preferably cooperation cell in the first cooperation cell pair set to distributing CoMP transfer resource, compared with prior art, lose under identical situation at community average throughput, can effectively promote the throughput of Cell Edge User, and promote the overall performance of edge customer.In the time that CoMP set is larger, performance boost is especially remarkable.
The step 22 of above-mentioned flow process, according to the different definition of the right transmission performance information in cooperation cell, corresponding, the dividing mode of the first cooperation cell pair set and the second cooperation cell pair set is also different.Even if the right transmission performance information in cooperation cell is defined as average spectral efficiency (ase) value and the average RSRP value of edge UE, also there is multiple implementation in the dividing mode of the first cooperation cell pair set and the second cooperation cell pair set.Fig. 3 shows a kind of preferred implementation, and this implementation can comprise the steps 31～33:
Step 31:CCN is according to the right cell combination information in cooperation cell receiving, search the cooperation cell pair that has two-way cooperation relation, and the right cell combination information in all cooperation cell that have two-way cooperation relation finding is put into the first cooperation cell pair set.
Such as, the cooperation cell that community 5 reports is to being (community 5, community 1), and the cooperation cell that community 1 reports is to being (community 1, community 5), and CCN judges that community 1 and community 5 are for existing the community pair of two-way cooperation relation.CCN puts into cooperation cell the CoMP set 1 that has two-way cooperation relation for depositing to (community 5, community 1) and (community 1, community 5).
Step 32:CCN judges in the first cooperation cell pair set whether have the community that meets first condition, and this first condition Wei Yige community is as the cooperation cell of other Liang Ge communities at least; If exist, determine that according to the right transmission performance information in cooperation cell all cooperation cell that comprise the community that meets this first condition are to the CoMP factor separately, and by the cooperation cell of CoMP factor maximum to being retained in the first cooperation cell pair set, the cooperation cell that other are comprised to the community that meets this first condition to deleting in the first cooperation cell pair set.
Such as, exist the CoMP set 1 of two-way cooperation relation to comprise 4 cooperation cell pair for depositing: (community 1, community 5), (community 5, community 1), (community 1, community 3) and (community 3, community 1), be respectively the cooperation cell of community 5 and community 3 due to community 1, therefore calculate the right CoMP factor in these 4 cooperation cell.If the value maximum of the CoMP factor of (community 1, community 5), is retained in (community 1, community 5) and (community 5, community 1) in CoMP set 1, cooperation cell is deleted from CoMP set 1 (community 1, community 3) and (community 3, community 1).
Step 33:CCN from the cooperation cell centering receiving remove the cooperation cell that meets second condition to, combined information right remaining cooperation cell is put into the second cooperation cell pair set, and this second condition is that main plot or the cooperation cell of cooperation cell centering is described the first pair set Nei community, cooperation cell.
Such as, the cooperation cell that community 5 reports is to comprising (community 5, community 1), the cooperation cell that community 1 reports is to comprising (community 1, community 5) and (community 1, community 2), the cooperation cell centering that community 2 reports does not comprise (community 2, community 1), by (community 5, community 1) and (community 1, community 5) put into for depositing after the CoMP set 1 that has two-way cooperation relation, in Already in CoMP set of community 11, therefore resource is occupied, need the cooperation cell that comprises community 1 deleting (no matter this cooperation cell to small area 1 as main plot or cooperation cell), need to delete (community 2 here, community 1), to delete rear remaining cooperation cell to putting into the CoMP set 2 that only has unidirectional cooperation relation for depositing.
Preferably, in the step 23 of above-mentioned flow process, in the situation that adopting the transmission of alone family, CCN is being cooperation cell in the first cooperation cell pair set when distributing CoMP transfer resource, CoMP transfer resource can be distributed to the cooperation cell pair that more needs to carry out cooperation transmission more, to improve the throughput of edge customer.
Fig. 4 show a kind of CCN be cooperation cell in the first cooperation cell pair set to distributing the preferred implementation of CoMP transfer resource, as shown in the figure, this process can comprise the following steps 41～42:
Step 41:CCN determines according to the right transmission performance information in cooperation cell the CoMP factor that each cooperation cell is right.If do not comprise the CoMP factor calculating in the right transmission performance information in the cooperation cell that community reports, CCN need to calculate the CoMP factor according to the average spectral efficiency (ase) value of the edge customer comprising in transmission performance information and average RSRP value, if comprised the CoMP factor in the right transmission performance information in the cooperation cell that community reports, can be without double counting again.

Step 52:CCN according to CoMP factor order from big to small to all cooperation cell in the second cooperation cell pair set to sorting, the right priority of resource allocation in cooperation cell after sequence reduces successively.
Preferably, after sequence, can also travel through each cooperation cell pair according to the order after sequence, if the main plot of the cooperation cell centering traversing current or cooperation cell have become sequence right cooperation cell, preceding other cooperation cell, remove the right cooperation relation in the current cooperation cell traversing.
Such as, if to only exist the CoMP set 2 of unidirectional cooperation relation to sort for depositing after, CoMP set 2 comprises following cooperation cell pair: (community 1, community 2), (community 3, community 1), (community 3, community 2) and (community 4, community 6), due to (community 3, community 2) Zhong community 2 become and come this cooperation cell to (community 1 before, community 2) in cooperation cell, therefore (community 3, community 2) deleted from CoMP set 2.
Step 53:CCN according to priority of resource allocation be cooperation cell in the second cooperation cell pair set to distributing CoMP transfer resource, that is, give sequence preceding cooperation cell pair CoMP transfer resource priority allocation.
The specific implementation process of the step 23 by above-mentioned flow process can be found out, two communities that have a two-way cooperation relation between when each own edge customer, throughput hoisting is now obvious, promotes the throughput of edge customer without the throughput of sacrificing central user; For the community pair that does not have two-way cooperation relation, now resource is distributed to the community that needs most cooperation by the scheme of sequence, thereby made CoMP gain obviously.
