Description

Configuration method, feedback method, base station and the terminal of channel state information

Technical field

The present invention relates to the communications field more particularly to a kind of configuration method of channel state information, feedback method, base station and Terminal.

Background technology

System is after it experienced the several versions of R8/9/10 for long term evolution (Long Term Evolution, abbreviation LTE), again R11 technologies are accurately studied successively.R8 products in part start gradually commercial at present, and R9 and R10 need further product programming.

R8 the and R9 stages are being experienced, R10 increases many new characteristics, such as demodulation ginseng again on the basis of the above two Examine signal (DemodulationReference Signal, DMRS), channel state information reference signals (Channel State Information Reference Signal, CSI-RS) etc. pilot tones characteristic, 8 antennas support etc. transmission and feedback characteristics etc., Particularly inter-cell interference offsets enhancing (ehanced Inter-Cell Interference Cancellin, eICIC) technology On the basis for considering R8/9ICIC, the interference avoidance technique between cell is further considered.For between solution cell The technology of interference problem mainly considers that the area interference under homogenous networks avoids at R10 initial stages in stage, wherein mainstream the considerations of eICIC Technology and multipoint cooperative (Coordinated Multi-point, CoMP) technology.CoMP is exactly multiple node cooperations as its name suggests Carry out transmission data in identical running time-frequency resource or different running time-frequency resources to one or more UE.Technology can be reduced in this way Interference between cell improves the throughput of cell edge, expands MPS process.But due to discussing that the later stage considers isomery Net introduces more scenes, and the time restriction of complexity and the R10 discussion of CoMP technologies is final to determine not draw in the R10 stages Enter additional CoMP standardized contents, but the demand of CoMP parts can be considered in design CSI-RS to design, so CoMP Technology is after 60bis meetings with regard to without carrying out further discussion.

In R11 be discussed the initial research stage (Study Item, SI), mainly by planning scene and the various transmission skills of CoMP Art determines unified assessment framework, assesses to prove that CoMP technologies can obtain apparent performance by the CoMP in 2 stages Gain.Be recently completed CoMP SI conclusions be need in CoMP technologies joint transmission (Joint Transmission, JT), dynamic cell selection (Dynamic Point Selection, DPS) is silent (with/without muting), and cooperation is adjusted Spend (Coordinated Scheduling, CS) with/without muting, cooperative beam excipient (Coordinated Beamforming, CB) it conducts further research.

Need to consider first before the various technical research to CoMP is which CoMP technologies have for R8/9/10 technologies How a little differences, the notice of CoMP measuring assemblies is supported including the control signaling of CoMP, and CoMP differences how to be supported to transmit The demand of technology, if UE measure and report multiple nodes channel state information (Channel State Information, CSI) etc..It is one of matter of utmost importance that CoMP technologies needs solve that how wherein UE, which measures and report the CSI of multiple nodes,. Current discuss of the feedback of CoMP can be mainly divided into periodic feedback and aperiodicity feedback, and aggregated channel information feedback is gathered with non- Close feedback of channel information.So-called aggregated channel information feedback refers to that the channel information multiple nodes aggregates into node Channel information carries out global feedback.As measuring assembly includes two nodes, the channel information H1 of node 1, the channel information of node 2 H2, it is a big channel information H=[H1 that at this moment UE, which first polymerize two node channels,；H2], then measuring correlometer It calculates and feeds back.Non-polymeric feedback of channel information can be divided into separate single cell feedback and separate single cell feedback plus minizone school again Positive information.So-called separate single cell feedback refers to that the channel information according to each node independently measures correlation computations and anti- Feedback.So-called separate single cell feedback plus minizone control information refer to that the channel information according to each node independently measures phase It closes and calculates, and calculate phase and/or amplitude information between each node and fed back.For aggregated channel information including It polymerize the feedback of CQI, the CQI that polymerization CQI refers to UE sides feedback is that one or more corresponding CSI-RS configuration information is surveyed The polymerization CQI, UE of amount find the time-frequency location of corresponding CSI-RS using multiple CSI-RS configuration informations, are obtained so as to measure Precoding value information and the interference information obtained using other pilot tones, are calculated, and at this moment UE assumes that one or more The corresponding node of a CSI-RS configuration information to its transmission data, so as to obtain this multiple node carry out joint send it is corresponding CQI value.Due to the polymerization that a polymerization CQI may correspond to one or CSI-RS configuration information measures, such as measurement set Conjunction can include 3 CSI-RS configuration informations, and at this moment polymerizeing a CSI-RS configuration information has 3 kinds of possibility, polymerize two CSI-RS configuration information has 3 kinds of possibility, and three CSI-RS configuration informations of polymerization have a kind of possibility, in total 7 kinds of possibility, so for Polymerize CQI there are many may, without it is a kind of may can be called polymerization may.

For CSI of traditional R8/R9/R10 user due to only needing back services cell, so in same carrier wave On periodic feedback and non-periodic feedback are needed to consider single cell capacity, especially for Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) only needs to optimize the feedback of single cell.At present In view of coding, mixed self-adapting request retransmission (Hybrid Adaptive Request Retransmission, HARQ) ratio Special number etc., for the CSI feedback of a UE 11 bits of maximum support in a PUCCH sub-frame of uplink.The composition of 11 bits is most The 7 of the big pre-coding matrix instruction (Precoding Matrix Indicator, PMI) that 4 bits can be considered and two code words The channel quality instruction (Channel Quality Indicator, CQI) of bit (considers that the difference of CQI between different code words is anti- Feedback).CoMP is due to that will consider the CSI feedback for multiple cells, it is desirable that the PUCCH capacities of N*11 bits, but at present PUCCH capacity can not meet this requirement, so needing a set of rational feedback scheme inadequate to solve PUCCH capacity The problem of using.It is contemplated that compressed feedback signaling, but CoMP has the precision of CSI higher requirement, particularly JT Even JT-MU proposes high requirement to CSI accuracy, so performance loss caused by compression may result in CoMP The decline of energy gain.Another consideration may be to improve the capacity of PUCCH, need to redesign the feedback format of PUCCH, this Sample will certainly bring larger standardization effort.If it is considered that for the difference of CSI feedback requirement between the different mode of CoMP With the adaptive switching that may require a guarantee that different mode, this Feedback Design may be just more complicated.So under discussion Consider to introduce the concept that can ensure information and/or introducing polymerization CQI between the node that cooperation transmission mode flexibly switches.Most It discusses that polymerization CQI can obtain the performance similar with information+polymerization CQI between node is introduced in a near meeting, does not at this moment have There is the feedback for comparing and introducing information between additional node, meeting at present is also continuing with whether introduce the anti-of node section information Feedback.But the concept for introducing polymerization CQI is all considered in both the above scheme.For polymerize CQI concept be to feed back it is multiple The CQI value that node aggregation generates, the interstitial content of polymerization can be the arbitrary number node of all nodes in measuring assembly Combination, such as comprising 6 nodes in measuring assembly, at this moment possible combination includes 63 kinds of situations, if it is considered that limitation maximum Aggregation number, combination at this moment includes 41 kinds of possibility.Once if feedback or multiple subframes feed back various situations to UE Multiple polymerization CQI, base station side how to know UE feedback is which node combination, this point need in base station side and UE Side is there are one unified regulation, and otherwise base station side can not know the polymerization CQI for receiving feedback is the combination of which node.

Periodic feedback and non-periodic feedback can be mainly divided into for the feedback of R10.

Uplink authorization or random access authorization control signaling is needed to trigger non-periodic feedback non-periodic feedback.It is non- The feedback model in period can be divided into following several：
