METHOD AND SYSTEM FOR UPLINK COOPERATIVE MULTIPOINT

摘要

Disclosed in the present invention is a method and system for uplink cooperative multipoint (CoMP), said method comprising: a service station obtains service channel state information and cooperative channel state information; and a precoding matrix used at the time a terminal sends uplink data is determined on the basis of the service channel state information and the cooperative channel state information. By means of the service station determining, on the basis of the obtained service channel state information and the obtained cooperative channel state information, the precoding matrix of the uplink data sent by the terminal, and then receiving data by means of JR technology after interference is reduced prior to sending, and the present invention raises the signal-to-interference-plus-noise ratio of an uplink reception signal, thereby realizing uplink CoMP data transmission and enhancing system efficiency.
