Description
Technical field
The present invention relates to the communications field, in particular to a kind of processing side of channel status reference signal (CSI-RS)
Method and device.
Background technology
Long Term Evolution (Long Term Evolution, referred to as LTE) system after it experienced the several versions of R8/9/10,
Accurately study R11 technologies successively again.R8 products in part start progressively commercial at present, and R9 and R10 need further product programming.
R8 the and R9 stages are being experienced, R10 adds many new characteristics, such as demodulation ginseng again on the basis of the above two
Examine signal (Demodulation Reference Signal, referred to as DMRS), channel state information reference signals (Channel
State Information Reference Signal, referred to as CSI-RS) etc. pilot tone characteristic, 8 antennas support etc. transmission and
Feedback characteristics etc., particularly inter-cell interference offset enhancing (ehanced Inter-Cell Interference
Cancellin, referred to as eICIC) technology is on the basis for considering R8/9ICIC, the further interference between consideration cell
Avoid technology.Mainly consider that the cell under homogenous networks is done initial stage in stage in R10 for the technology of interference problem between solution cell
Disturb and avoid, wherein the consideration eICIC technologies of mainstream and multipoint cooperative (Coordinated Multi-point, referred to as CoMP)
Technology.CoMP as the term suggests exactly multiple nodes cooperate to one or more UE identical running time-frequency resource or it is different when
Frequency resource sends data.So technology can reduce the interference between cell, improve the throughput of cell edge, expand cell
Covering.But due to discussing that the later stage considers heterogeneous network and introduces more scenes, complexity and the R10 discussion of CoMP technologies
Time restriction, it is final to determine not introducing extra CoMP standardized contents in the R10 stages, but can be examined in design CSI-RS
Consider the demands of CoMP parts to design, thus CoMP technologies after 60bis meetings just without the further discussion of progress.
The collision problem of CSI-RS configurations and paging (Paging), PSS/SSS, PBCH and SIB1 is considered in R10, it is main
Think if CSI-RS sends the punching that can cause data in above-mentioned subframe, cause system message lack or false retrieval it is general
Rate increase, so as to cause CSI-RS seriously affecting for system message, in order to avoid the generation of problem above, and as far as possible
Raising CSI-RS multiplexing factor, increase the transmittable subframe of CSI-RS, provided in R10：UE is not expected in subframe type 2
Special subframe, send the subframe of PBCH, send PSS/SSS subframes, send SIB1 subframes and send the subframe of paging message
Receive CSI-RS.
In R11 talking stages, UE can receive CSI-RS resource configuration information, this multiple CSI-RS resource matches somebody with somebody confidence
Breath, the CSI-RS that can represent different nodes or cell send information.If multiple nodes or cell configuration difference
CSI-RS resource configuration information, the hypothesis according to current UE be it is of problems, i.e. UE can only receive service node or
