Preprocessing method, base station, and system for cooperative communication
Abstract:
A preprocessing method for cooperative communication and a base station and a system for executing the method are provided. The method includes: obtaining a common base station group from a cooperative base station group of a user terminal, in which the common base station group includes a set of base stations providing a cooperative service for other user terminals in the cooperative base station group; and calculating a first precoding matrix of the user terminal according to the common base station group, in which the first precoding matrix is used to perform elimination preprocessing on interference from the user to other user terminals served by the common base station group. The method reduces Multi-User Interference (MUI).
