Description
Technical field
The present invention relates to the communications field, more particularly to a kind of collocation method of channel state information reference signals, measurement letter
Method, base station and the terminal in road.
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 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 again on the basis of the above two, for example, DMRS
(Demodulation Reference Signal, demodulated reference signal), CSI-RS (Channel State Information
Reference Signal, channel state information reference signals) etc. pilot tone characteristic, 8 antennas support etc. transmission and feedback characteristics etc.
Deng particularly eICIC (ehanced Inter-Cell Interference Cancellin, inter-cell interference offset enhancing)
Technology further considers that the interference between cell avoids skill on the basis for considering R8/9ICIC (inter-cell interference counteracting)
Art.Mainly consider that the area interference under homogenous networks avoids initial stage in stage in R10 for the technology of interference problem between solution cell,
Wherein the consideration eICIC technologies of mainstream and CoMP (Coordinated Multi-point, multipoint cooperative) technology.CoMP cares for name
Think of justice exactly multiple nodes cooperate to be sent to one or more UE in identical running time-frequency resource or different running time-frequency resources
Data.So technology can reduce the interference between cell, improve the throughput of cell edge, expand MPS process, but by
In discussing that the later stage considers heterogeneous network and introduce more scenes, time restriction that the complexity and R10 of CoMP technologies discuss,
It is final to determine not introducing extra CoMP standardized contents in the R10 stages, but CoMP parts can be contemplated in design CSI-RS
Demand design, so CoMP technologies after the 60bis meetings with regard to without carrying out further discussion.
CSI-RS configurations and Paging (paging), PSS (PrimarySynchronization are considered in R10
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
Block of information 1) collision problem, mainly think if CSI-RS sends the punching that can cause data in above-mentioned subframe, cause be
Unite the probability increase of message lacks or false retrieval, so as to cause CSI-RS seriously affecting for system message, in order to avoid with
The generation of upper problem, and the multiplexing factor of CSI-RS is improved as far as possible, increase the transmittable subframe of CSI-RS, in R10
Regulation：UE does not expect the special subframe in subframe type 2, sends the subframe of PBCH, sends PSS/SSS subframes, sends SIB1
Frame and the subframe reception CSI-RS for sending paging message.
In R11 talking stages, UE can receive CSI-RS resource configuration information, this multiple CSI-RS resource configuration information,
The CSI-RS that different nodes or cell can be represented sends information.If multiple nodes or cell configuration are different
CSI-RS resource configuration information, the hypothesis according to current UE are of problems, i.e. UE can only receive service node or small
Paging (paging) configurations in area, at this moment if receiving other CSI-RS resource still according to the Paging configurations of this cell
When, if this cell Paging subframes and other CSI-RS resource subframes are collided, at this moment, it still can be received except this clothes in real time
The CSI-RS being engaged in outside node, can this subframe be referred to as pseudo- to collide subframe.If other CSI-RS resource subframes and corresponding
Paging subframes are collided, but the subframe is not the paging subframes of service node or cell again, and at this moment UE still can be upper
Planar survey CSI-RS, at this moment can causing to measure the result is that mistake, the then mistake of UE link circuit self-adaptings.
