Description

The feedback method of control information between node
Technical field
The present invention relates to the communications field, in particular to the feedback method of control information between a kind of node.
Background technology
The R11 technology is accurately studied again successively by Long Term Evolution (Long Term Evolution is called for short LTE) system after having experienced the several versions of R8/9/10.At present part R8 product also begins progressively commercially, and R9 and R10 remain further product programming.
experiencing R8 and R9 after the stage, R10 has increased again a lot of new characteristics on the above two basis, DMRS (Demodulation Reference Signal for example, demodulated reference signal), CSI-RS (Channel State Information Reference Signal, channel state information reference signals) the pilot tone characteristic such as, the transmission such as 8 antenna supports and feedback characteristics etc., eICIC (ehanced Inter-Cell Interference Cancellin particularly, between node, Interference Cancellation strengthens) technology, this technology is on the basis of having considered R8/9ICIC, further considered the interference avoidance technique between node.Consider mainly at the R10 initial stage in stage that node under homogenous networks disturbs for the technology that solves the interference problem between node and avoid, wherein, the consideration eICIC technology of main flow and CoMP (Coordinated Multi-point, multipoint cooperative) technology.CoMP is as the term suggests be exactly that a plurality of node cooperations send data at identical running time-frequency resource or different running time-frequency resources to one or more UE.This technology can reduce the interference between node, improves the throughput of node edge, enlarges coverage.But, introduced more scene owing to considering heterogeneous network in the discussion later stage, the time restriction that the complexity of CoMP technology and R10 discuss, final decision is not introduced extra CoMP standardized content in the R10 stage, yet, the demand that can consider the CoMP part at design CSI-RS designs, so the CoMP technology is not just carried out further discussion after the 60bis meeting.
At R11, initial stage SI (Study Item is discussed, conceptual phase) stage, mainly determine unified assessment framework by planning scene and the various transmission technologys of CoMP, the CoMP by 2 stages assesses to prove that the CoMP technology can obtain obvious performance gain.Need to be to (the Joint Transmission of the JT in the CoMP technology in the CoMP SI conclusion of completing recently, joint transmission), DPS (Dynamic Point Selection, dynamic node is selected) with/without muting, CS (Coordinated Scheduling, cooperative scheduling) with/without muting, CB (Coordinated Beamforming, cooperative beam excipient) further studies.
What needed at first to consider before the various technical research to CoMP is which difference is the CoMP technology have for the R8/9/10 technology, how to support the notice of CoMP measuring assembly comprising the control signal of CoMP, how to support the demand of the different transmission technologys of CoMP, how UE measures and reports CSI (Channel State Information, channel information) of a plurality of nodes etc.Wherein how to measure and report the CSI of a plurality of nodes are one of matters of utmost importance of solving of CoMP Technology Need to UE.The feedback that CoMP is discussed at present mainly can be divided into periodic feedback and aperiodicity feedback, aggregated channel information feedback and non-polymeric feedback of channel information.So-called aggregated channel information feedback refers to the channel information that the channel information of a plurality of nodes is aggregated into a node and carries out global feedback.Comprise two nodes as measuring assembly, the channel information H1 of node 1, the channel information H2 of node 2, two node channels of the at this moment first polymerization of UE are a large channel information H=[H1; H2], then measuring correlation computations and feedback.Non-polymeric feedback of channel information can be divided into again separate single node feedback and separate single node feedback adds control information between node.So-called separate single node feedback refers to independently measure correlation computations and feedback according to the channel information of each node.So-called separate single node feedback adds that between node, control information refers to independently measure correlation computations according to the channel information of each node, and calculates each internodal phase place and/or amplitude information and feed back.
For traditional R8/R9/R10 user, owing to only needing the CSI of feedback service node, so only need to consider that for periodic feedback and non-periodic feedback the single node capacity gets final product on same carrier wave, particularly only need to be optimized the feedback of single node for PUCCH and get final product.Consider at present coding, HARQ (Hybrid Adaptive Request Retransmission, the mixed self-adapting request retransmission) bit number etc., for a UE maximum CSI feedback of supporting 11 bits in a PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) sub-frame of uplink.The composition maximum of 11 bits can be considered PMI (the Precoding Matrix Indicator of 4 bits, pre-coding matrix indication) and the CQI of 7 bits of two code words (Channel Quality Indicator, channel quality is indicated) (considering the differential feedback of CQI between different code words).Because CoMP will consider to feed back for the CSI of a plurality of nodes, require the PUCCH capacity of N*11 bit, but present PUCCH capacity can't meet this requirement, so need a rational feedback scheme of cover solve the not enough problem of PUCCH capacity.What easily expect is the compressed feedback signaling, but CoMP has higher requirement for the precision of CSI, particularly JT or even JT-MU have proposed higher requirement to the CSI accuracy, so the performance loss that compression causes may cause the decline of CoMP performance gain.Another consideration may be the capacity that improves PUCCH, needs the feedback format of redesign PUCCH, will certainly bring larger standardization effort like this.If switch for the difference of CSI feedback request and the self adaptation that may need to guarantee different mode between the different mode of consideration CoMP, this Feedback Design may be just more complicated.If consider the sensitivity for control information between node of JT, particularly arrive the asynchronism(-nization) of same UE between different nodes, perhaps the time delay difference of the UE of two the different nodes arrival of UE MU-JT pairings all can cause on the performance of JT larger impact, so for JT, how to consider the feedback in the cycle of control information between node, the time delay of how to resist this different node same UE of arrival or different UEs is different, and when guaranteed capacity, guarantee the accuracy of CSI and the less standardization effort this patent problem that need to solve just.
As seen, in the prior art, in the time of can't realizing avoiding a plurality of nodes to one or more UE feedback on the basis of the accuracy of the capacity that guarantees PUCCH and CSI between the node of each node control information conflict appears, reduced the accuracy of control information between the node of each node feedback.
