Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of transmission method and equipment of channel condition information.
Background technology
LTE-A(Long Term Evolution-Advanced, the follow-up evolution of Long Term Evolution) adopt identical networking, when increasing substantially the availability of frequency spectrum, also can cause the subscriber signal decline of cell edge serious, also can be subjected to higher interference simultaneously from other sub-districts, if signal fadeout and interference problem are not handled, will have a strong impact on the experience of edge customer.Multipoint cooperative (Coordinated Multiple Point, CoMP) technology is by introducing information interaction and the joint transmission between many sub-districts, not only can improve signal quality and also can reduce presence of intercell interference, thereby can increase substantially the data transmission performance of Cell Edge User.
Present multipoint cooperative transmission plan roughly comprises: dynamic transmission point selection (Dynamic Point Selection, DPS), cooperative beam figuration (Coordinated Beamforming, CBF) and joint transmission (Joint Transmission, JT), also can be the hybrid plan of above 3 class transmission plans.Such as, DPS and CBF combine, and the main point that transmits is determined by Dynamic Selection, and is realized cooperative beam figuration etc. by combined dispatching between the non-main transmission outer cooperation transmission point.In real system, a transmission mode may comprise multiple transmission plan, supports the mode switch between all kinds of transmission plans.In order to guarantee the transmission performance and the stability of a system better, often need in the transmission mode of CoMP transmission to support to support switching to unicast.
System is by the different CSI-RS(Channel State Information Reference Signal of configuration, channel state information reference signals) make that (User Equipment UE) can measure the down channel of each " transmission point " to subscriber equipment.It should be noted that " transmission point " may not be the transmission point of a physics, and may be a virtual transmission point that each virtual transmission is o'clock corresponding to a CSI-RS resource, constitute by the transmission point of one or more physics.
After realizing that down channel is measured, carry out feedback information according to the needed channel condition information of transmission plan.All kinds of transmission plans need corresponding channel condition information support.Such as, DPS needs the channel condition information of a plurality of transmission points, perhaps the channel condition information of some transmission points and the pairing CSI-RS index information of this transmission point.CBF and irrelevant JT need lead the not limited channel condition information and the non-main channel condition information that transmits the RI=1 of point of RI of transmission point.Relevant JT need lead the not limited channel condition information of RI of transmission point, the channel condition information of the RI=1 of each transmission point, and the relative phase information of each transmission point.So-called main transmission point be among DPS and the CBF to the transmission point of UE transmission data, perhaps JT if when returning back to unicast to the transmission point of UE transmission data.
During actual the realization, can realize general feedback by the mode of classification feedback, promptly (measuring assembly is that network is the transmission point set of UE configuration to measuring assembly, UE need observe the channel condition information of the transmission point in the measuring assembly, and realize feedback) in the channel condition information of each transmission point feedback single-point, phase information and/or the amplitude information between the feedback transmission point respectively again.Network is based on the synthetic channel condition information of transmission in the measuring assembly being put UE of this two parts information.Comprising two transmission points with measuring assembly is example, the channel of two transmission point UE be designated as respectively and, UE is that two transmission points are selected pre-coding matrix and (the pre-coding matrix here is channel condition information) respectively, and then the phase place of two minizones and amplitude information can be chosen as follows:
Wherein belong to predefined code book set.And if columns be designated as
M, the diagonal matrix that is then,
M=1 deteriorates to a scalar.If
gBe scalar, then its code book set A can be the point in the 16QAM planisphere:
Also can be the point in the QPSK planisphere:
In the such scheme, UE puts on an equal footing all transmission points when feedback.And in fact, the effect in various schemes of these transmission points is also inequality.In cooperative scheduling/wave beam forming and dynamic transmission point selection scheme, have only 1 point to send data to UE, the required precision meeting of the channel information of this transmission point is higher than other transmission point, and this transmission point should the support space multiplexing transmission (promptly allow RANK〉1).Dynamic transmission point selection scheme in fact only needs the channel condition information of 1 transmission point, and in order to support other scheme, information of other transmission points also need be fed back, but to not what meaning of dynamic transmission point selection scheme.The JT case supports high RANK transmission can't bring tangible performance boost, but can bring very high complexity to feedback, therefore supports the feedback of JT scheme only to need each to transmit the channel condition information of the RANK 1 of point.
At existing Long Term Evolution (Long-Term Evolution, LTE) in the system, support two class channel condition information feedback systems, promptly based on Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) periodic feedback and based on Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) aperiodic channel status information feedback.Periodic feedback based on PUCCH comprises 4 class feedback models (Reporting Mode), pattern 1-0,2-0,1-1 and 2-1.All kinds of feedback models guarantee replacement 1 altogether, 1a, 2,2a, 2b, 2c, 3,4,5,6 totally 10 kinds of Report Types (Reporting Type).Wherein pattern 1-0 and 2-0 support not comprise the channel condition information feedback of PMI feedback, can be used for TDD(Time Division Duplexing, time division duplex) multiple-input and multiple-output (Multiple-Input Multiple-Output, MIMO) transmission in the system.Table 1 shows the CQI(Channel Quality Indicator of PUCCH CSI feedback model, the channel quality indication) and the PMI feedback kind, table 2 shows the PUCCH Report Type payload of each PUCCH feedback model and mode state.
