A method for transmitting control signaling, an apparatus for processing control signaling and a terminal are provided. A base station transmits evolved control signaling to an evolved terminal on M downlink subframes in a radio frame, wherein M is an integer greater than or equal to 1 and less than N, and N is the number of the downlink subframes in the radio frame. The above technical solution enhances basic control signaling of an LTE-series standard, reduces system overhead and terminal energy consumption, meets demands for future development of the industry, solves the problem of large system overhead and high terminal energy consumption due to the wireless communication standards, and meanwhile also gives sufficient consideration to backward compatibility of the system, and better meets demands of data users rapidly developing and future development of the wireless communications industry.

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. The coordinating method and device of the disclosure can reduce or eliminate interference among users at a border through downlink resource allocation and precoding coordination between adjacent cells, thereby enhancing performance of the entire network.
