Description
Technical field
The present invention relates to the communications field, in particular to processing method and the device of a kind of channel status reference signal (CSI-RS).
Background technology
The R11 technology is accurately studied again successively by Long Term Evolution (Long Term Evolution is referred to as LTE) system after having experienced the several versions of R8/9/10.At present part R8 product begins progressively commercially, and R9 and R10 remain further product programming.
Experiencing R8 and R9 stage, R10 has increased again a lot of new characteristics on the above two basis, demodulated reference signal (Demodulation Reference Signal for example, referred to as DMRS), channel state information reference signals (Channel State Information Reference Signal, referred to as CSI-RS) etc. the pilot tone characteristic, the transmission such as 8 antenna supports and feedback characteristics etc., particularly presence of intercell interference is offset and is strengthened (ehanced Inter-Cell Interference Cancellin, referred to as eICIC) technology on the basis of having considered R8/9ICIC, further consider the interference avoidance technique between the residential quarter.Consider mainly that at the R10 initial stage in stage the area interference under the homogenous networks avoids for the technology that solves interference problem between the residential quarter, wherein the consideration eICIC technology of main flow and multipoint cooperative (Coordinated Multi-point is referred to as CoMP) technology.CoMP is as the term suggests be exactly that a plurality of node cooperations send data to one or more UE at identical running time-frequency resource or different running time-frequency resources.Technology can reduce the interference between the residential quarter like this, improves the throughput of cell edge, enlarges the residential quarter and covers.But introduced more scene owing to having considered 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, but 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.
CSI-RS configuration and paging (Paging) in R10, have been considered, PSS/SSS, the collision problem of PBCH and SIB1, mainly think if CSI-RS transmission in above-mentioned subframe can cause the punching of data, cause the probability of system message disappearance or false retrieval to increase, thereby cause CSI-RS having a strong impact on for system message, generation for fear of above problem, and improve as much as possible the multiplexing factor of CSI-RS, increase the sent subframe of CSI-RS, stipulate in R10: UE is not desirably in the special subframe of subframe type 2, sends the subframe of PBCH, send the PSS/SSS subframe, the subframe that sends SIB1 subframe and transmission paging message receives CSI-RS.
In R11 talking stage, UE can receive the CSI-RS resource allocation information, these a plurality of CSI-RS resource allocation informations, and the CSI-RS that can represent different nodes or residential quarter sends information.If a plurality of nodes or cell configuration different CSI-RS resource allocation informations, hypothesis according to present UE is in-problem, it is the Paging configuration that UE can only receive service node or residential quarter, if when at this moment still configuring to receive other CSI-RS resources according to the Paging of this residential quarter, if this residential quarter Paging subframe and the collision of other CSI-RS resource subframes, at this moment it still can receive the CSI-RS except this service node in real time, can claim this subframe to be pseudo-collision subframe.If other CSI-RS resource subframes and corresponding Paging subframe collision, but this subframe is not again the paging subframe of service node or residential quarter, at this moment UE still can measure CSI-RS in the above, and it is wrong at this moment can causing the result who measures, and causes the mistake of UE link circuit self-adapting.So consider a plurality of CSI-RS resource distributions in the R11 stage, need to further consider if avoid collision problem or the pseudo-collision problem of CSI-RS subframe and Paging.
