Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of transmission method and equipment of field feedback.
Background technology
CoMP(Coordinated Multipoint Transmission/Reception, multi-point cooperative transmission) technology refers to the cooperation between the multiple transfer points that separate on geographical position.In general, multiple transfer points are base stations of different districts, or multiple RRH(Remote Radio Head of same cell base station control, remote radio).By the cooperation transmission between multiple transfer points, can effectively reduce the interference between different transfer points, improve user's's (particularly Cell Edge User) throughput.
Descending CoMP technology comprises CS/CB(Cooperative Scheduling/Beamforming, cooperative scheduling/wave beam forming) and Combined Treatment (Joint processing).Wherein:
Cooperative scheduling is by the coordination of the time between transfer point, frequency and space resources, avoids or reduces interference each other; Because the interference of minizone is the principal element of restriction community marginal user performance, therefore cooperative scheduling, by reducing the interference of minizone, can improve community marginal user performance.
Combined Treatment comprises the switching of dynamic transmission point and combines the two kinds of modes that send.In dynamic transmission point switching mode, the transfer point to user's transmitted signal is dynamically switched in base station, selects optimal transmission point transmission data; Switch for realizing dynamic transmission point, base station need to obtain by feedback channel the channel information of multiple optional communities, or obtains optimal transmission point channel information.In associating send mode, multiple transfer points send data to user simultaneously, receive signal to strengthen user, and possible interference signal is converted into useful signal, improve user SINR(Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio).
But above-mentioned CoMP technology is not considered backhaul(back haul link) time delay and capacity limit, and if cooperative transmission is to carry out between different base station, the backhaul between base station may exist compared with long time delay and capacity limit; Now CoMP technology (particularly Combined Treatment) will be difficult to carry out; Under this scene, in order to make user can obtain the gain of multipoint cooperative, the current CoMP having proposed between inter-eNodeB CoMP(base station) technology (as multi-flow(multithread) transmission plan).
In multi-flow transmission plan, allow multiple base stations to dispatch independently a user simultaneously, thereby improve user's transmission performance and each local resource utilance; As shown in Figure 1, be the multi-flow transmission plan schematic diagrames of two base stations to same user, Liang Ge community is by resource and configuration information dispatched users separately, user simultaneously schedule information and the transmission data of Dui Liangge community detects and respective feedback, each base station receives the feedback information (each base station can receive only feedback information corresponding to this base station or receive the feedback information of all base stations) from user, then uses the feedback information of this base station to carry out follow-up scheduling.
Realizing in process of the present invention, inventor finds at least to exist in prior art following problem:
