DATA TRANSMISSION METHOD, TRANSMISSION END AND RECEPTION END IN COOPERATIVE COMMUNICATION SYSTEM

摘要

The present invention provides a data transmission method, a transmission end and a reception end in a cooperative communication system. The method includes that: a first transmission end performs precoding on the load data of itself using a first precoding matrix, and acquires first precoded data (101); the first transmission end performs precoding on cooperative data using a second precoding matrix, and acquires second precoded data to eliminate interference at the reception end to the first precoded data caused by data transmitted from another transmission end (102); wherein, the cooperative data includes at least a part of the load data which the first transmission end receives from another transmission end; the first transmission end transmits the first and second precoded data which are after precoding to the reception end (103). With the method provided by the embodiments of the present invention, the first transmission end eliminates the interference at the reception end to the first precoded data caused by the data transmitted from another transmission end by using different precoding matrices.
