  • Coordinating method and device for multi-input multi-output precoding of downlink multi-base station
    Patent number: 9077404
    Abstract: The disclosure discloses a method for coordinating downlink MIMO precoding among multiple BSs, including that: each BS first performs independent resource allocation to allocate resources to users of each BS, then receives PMI information fed back by a time-frequency resource block occupying MS in a respective cell, wherein the PMI information includes optimal and recommended or restrained PMIs corresponding to an MS; adjacent BSs perform information interaction with each other to acquire PMI information of MSs occupying the same time-frequency resource block in adjacent cells; and it is determined whether there is any conflict between MSs occupying the same time-frequency resource block in adjacent cells according to PMI information fed back by an MS in the current cell and interaction information from adjacent BSs, and a new PM is generated in a corresponding manner. The disclosure also discloses a device for implementing the method.
