Description

The configuration of channel state information reference resource and determining method, base station and terminal

Technical field

The present invention relates to the communications field more particularly to a kind of configuration methods of channel state information reference resources, determination side Method, base station and terminal.

Background technique

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

It experienced R8 the and R9 stage, R10 increases many new characteristics, such as DMRS again on the basis of the above two (Demodulation Reference Signal, demodulated reference signal), CSI-RS (Channel State Information Reference Signal, channel state information reference signals) etc. pilot tones characteristic, 8 antennas support etc. transmission and feedback characteristics etc. Deng especially eICIC (enhanced Inter-Cell Interference Cancelling, inter-cell interference counteracting increasing Technology is considering R8/9 ICIC's (Inter-Cell Interference Cancelling, inter-cell interference are offset) by force) On basis, the interference avoidance technique between cell is further considered.For solving the technology of interference problem between cell in R10 Initial stage in stage mainly considers that the area interference under homogenous networks avoids, wherein eICIC technology and CoMP the considerations of mainstream (Coordinated Multi-point, multipoint cooperative) technology.CoMP as the term suggests exactly multiple nodes cooperate to one or Multiple UE send data in identical running time-frequency resource or different running time-frequency resources.Technology can be reduced between cell in this way Interference improves the throughput of cell edge, expands MPS process.But due to discussing that the later period considers heterogeneous network and introduces more More scenes, the time restriction that the complexity and R10 of CoMP technology discuss, final decision do not introduce additional in the R10 stage CoMP standardized content, but the demand of the part CoMP can be considered in design CSI-RS to design, so CoMP technology exists With regard to without carrying out further discussion after 60bis meeting.

The configuration information of R10 CSI-RS mainly includes non-zero power CSI-RS configuration signal and zero energy CSI-RS configuration Signaling.Non-zero power CSI-RS configuration is main to be considered being notified each non-zero power in terminal side in the way of table index CSI-RS is in the running time-frequency resource position of a subframe, as shown in Table 1 and Table 2, and is configured and is notified by antenna port number Terminal side non-zero power CSI-RS occupy running time-frequency resource number corresponding antenna port and utilize sub-frame offset and week Phase indexes to notify terminal side in the subframe for receiving CSI-RS, as shown in table 3.

Resource impact of the table 1:CSI-RS in general cyclic prefix sub-frame configuration

Resource impact of the table 2:CSI-RS in extended cyclic prefix sub-frame configuration

Table 3:CSI-RS sub-frame configuration

The CSI-RS of zero energy notifies terminal side to need rate-matched using bitmap (bitmap) sequence of 16 bits Resource element.Sub-frame offset and the subframe where the zero energy CSI-RS of periodic notification terminal side, as shown in table 3.

The purpose of non-zero power CSI-RS mainly allows terminal side to measure CSI and feeds back to base station side.Zero energy CSI-RS Main purpose be in order to reduce data service for CSI-RS interference to improve measurement CSI accuracy, in base station side Notify the resource location of the CSI-RS of terminal side zero energy, terminal side assumes base station not in the resource location of the CSI-RS of zero energy Place PDSCH or other reference signals or channel.

R11 needs to consider influence of the CoMP for standard, in particular for the configuration and zero power for considering interferometry resource The configuration of rate CSI-RS resource.It discusses in newest 68bis meeting, can be obtained using the CSI-RS resource measurement interference of zero energy More accurately Interference Estimation performance is obtained, while can also partially be compatible with R10 version terminal, makes it through configuration zero energy CSI- RS come avoid interferometry resource for PDSCH punching caused by performance loss.If introducing zero energy CSI-RS in the R11 stage After the mode for measuring interference, then terminal side needs the rate-matched resource identified needs to include the following three types:

1. non-zero power CSI-RS resource.It is primarily referred to as base station side and sends CSI-RS in the way of 8 or 4 ports, eventually End side maximum can only support 4 or 2 ports, at this moment carry out rate-matched in the port position that other cannot be identified.Or base Stand side transmission CSI-RS, but terminal side uses feedback model 1-0, at this moment 2-0 3-0 mode does not need configuration CSI-RS Port, it is only necessary to configure zero energy CSI-RS.

2. zero energy CSI-RS resource is for reducing the interference that data service measures CSI-RS.

3. zero energy CSI-RS resource measures interference for terminal side on corresponding resource location.

The purpose configured for the 1st, 2 point with the zero energy CSI-RS of R10 is identical, is newly-increased zero energy for the 3rd point CSI-RS is used for interference measurement.So needing to include at least two there are new zero energy CSI-RS configuration mode for R11 Point, a part is used for interference measurement, and a part is used for rate-matched.In the application for the simplicity write, temporarily claim interference The zero energy CSI-RS of measurement is IMR (Interference Measurement Resource, interferometry resource), claims speed The matched zero energy CSI-RS of rate is RMR (Rate Matching Resource, rate-matched resource).

For traditional R8/9/10 system, due to CRS (Cell Specific Reference Signal, cell reference Signal) each effective subframe of downlink is sent, so terminal can carry out channel measurement or dry based on each subframe Measurement is disturbed, the effective subframe of each downlink can be a CSI reference resources, and for the system of R11, CSI-RS and IMR It all periodically configures, if being the calculating complexity that a CSI reference resources will lead to terminal according to each effective subframe Degree, especially for CoMP terminal, since this terminal needs to calculate and feed back the CSI (one of multiple CSI Process (process) Corresponding NZP (Non Zero Power, the non-zero power) CSI-RS configuration of a CSI Process and an IMR configuration), such as Fruit considers further that such terminal supports the carrier wave polymerization of maximum 5 carrier waves relatively high for the measurement complexity of terminal.In order to subtract The implementation complexity of few terminal, needs some means to optimize measurement and calculating of the terminal for reference resources.
