Embodiment
Inventor notices in realizing process of the present invention: in order to support various CoMP transmission plans, network equipment need to obtain transfer point to the channel condition information of UE, and the channel condition information that this channel condition information can report by UE obtains.
When UE reporting status information of channel, a kind of mode that reports is: the information that UE reports can be supported various transmission plans (as schemes such as CS/CB, JP and dynamic transmission point selection), and the feedback of UE is general.This, report under mode, when UE has reported after channel condition information, network equipment can be according to the suitable transmission plan of the selecting factors such as deployment scenario and professional qualification, and the concrete transmission plan of selecting is transparent to UE, and the flexibility ratio of realization is higher.
When actual realization, the mode that can feed back by classification realizes general feedback, to measuring assembly, (measuring assembly is that network equipment is a transfer point set of UE configuration, UE need to observe the channel condition information of the transfer point in this measuring assembly, the channel condition information of each transfer point feedback single-point and realization feedback), distinguishes phase information and/or the amplitude information between feedback transmission point afterwards.Afterwards, network equipment is based on the synthetic channel condition information that transfer point in measuring assembly is arrived to UE of this two parts information.
Take that to comprise two transfer points in measuring assembly be example, two transfer points are designated as respectively H to the channel of UE
1and H
2, UE is that two transfer points are selected respectively pre-coding matrix w
1and w
2(pre-coding matrix is channel condition information), the phase place of two minizones and amplitude information g can choose as follows:
Wherein, g belongs to predefined codebook set; If w
1and w
2columns be designated as M, the diagonal matrix that g is M * M, during M=1, g deteriorates to a scalar; If g is scalar, its codebook set A can be 16QAM(Quadrature Amplitude Modulation, digital modulator) point in planisphere, can be also QPSK(Quadrature Phase Shift Keying, Quadrature Phase Shift Keying) point in planisphere.
In such scheme, UE puts on an equal footing all transfer points when feedback.And in fact, the effect of these transfer points is not identical; In CS/CB and dynamic transmission point selection scheme, only have 1 point to send data to UE, the required precision meeting of the channel information of this transfer point is higher than other transfer point.
Therefore, if allow UE to comprise the information of the main transfer point of UE (main transfer point: UE recommend UE is carried out to the transfer point of transfer of data) in the information reporting, the situation that the channel condition information of each transfer point that UE reports can be recommended according to UE be optimized respectively design.For example, the main transfer point that UE recommends reports by higher precision, and other transfer points report by lower precision, or uses with respect to recommending the difference form of transfer point to report.
Based on above-mentioned discovery, the embodiment of the present invention provides a kind of definite method and apparatus of main transfer point, can realize the recommendation of UE to main transfer point.
In the prior art, the definite method of main transfer point comprises: network equipment specifies main transfer point and UE in measuring assembly, to select transfer point.Network equipment is specified in the method for main transfer point, cannot to main transfer point, make dynamic adjustment according to channel condition, and flexibility is poor.UE selects in the method for main transfer point in measuring assembly, transfer point in measuring assembly not necessarily all can be transmitted data to UE, as the packet of UE can only share to a part of transfer point by wired connection, other transfer point is controlled the interference to UE by CS/CB.
For the problems referred to above, in definite method and apparatus of the main transfer point that the embodiment of the present invention provides, network equipment by configuring a transmission subset in measuring assembly, make UE select main transfer point in the transmission subset of network equipment configuration, and by the identification feedback of main transfer point to network equipment, thereby can realize the selection of UE to transfer point, and then the channel condition information of different transfer points is realized to differentiation feedback, reasonably determine the transfer point that sends data to UE.
