Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of collocation method of channel state information reference signals, method, base station and the terminal of measurement channel.
Background technology
Long Term Evolution (Long Term Evolution is called for short LTE) system after having experienced the several versions of R8/9/10, is accurately studied again the R11 technology successively.At present part R8 product starts 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, for example, DMRS (Demodulation Reference Signal, 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, presence of intercell interference counteracting enhancing) technology is on the basis of having considered R8/9ICIC (presence of intercell interference counteracting), further consider the interference avoidance technique between residential quarter.Consider mainly that at the R10 initial stage in stage the area interference under homogenous networks avoids for the technology that solves interference problem between residential quarter, 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 to one or more UE at identical running time-frequency resource or different running time-frequency resources.Technology can reduce the interference between residential quarter like this, improve the throughput of cell edge, enlarging residential quarter covers, but owing to having considered heterogeneous network in the discussion later stage, introduced more scene, 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 at design CSI-RS, can consider that the demand of CoMP part designs, so the CoMP technology is not just carried out further discussion after the 60bis meeting.
CSI-RS configuration and Paging (paging) have been considered in R10, PSS (PrimarySynchronization Signal, primary synchronization channel)/SSS (Secondary Synchronization Signal, auxiliary synchronization channel), PBCH (Primary Broadcast Channel, main broadcast channel) and SIB1 (System Information Block 1, system information block 1) collision problem, 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, send 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, and these a plurality of CSI-RS resource allocation informations can represent that the CSI-RS of 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 Paging (paging) configuration that UE can only receive service node or residential quarter, if while at this moment still according to the Paging of this residential quarter, configuring to receive other CSI-RS resources, if this residential quarter Paging subframe and the collision of other CSI-RS resource subframes, at this moment, the CSI-RS that it still can receive in real time except this service node, 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 of measuring, then the mistake of UE link circuit self-adapting.
