    摘要： In a multi user communication system, subcarriers are allocated to subchannels using a quality measurement for each subchannel. An initial sub carrier is allocated to each subchannel, and a quality metric measured. Subsequent subcarriers are allocated in dependence upon the quality measurement for each subchannel. The subchannel with the lowest quality measurement receives the first allocation, and the subchannel with the highest quality measurement receives the last allocation. The subsequent allocation is repeated, following a re-sort of the subchannel quality measurements, until all of the subcarriers are allocated.

    摘要： A method and a device for performing space coordination among cells are disclosed in the present invention, and the method includes that a base station in a serving cell acquires the channel information of a terminal; the base station in said serving cell performs pre-scheduling to said terminal, according to the acquired channel information of said terminal and the service requirement of said terminal; the base station in said serving cell transfers the pre-scheduling information to the base station in said coordinated cell, so that the base station in said coordinated cell performs coordinated scheduling/coordinated beam-forming with the base station in said serving cell together, according to said pre-scheduling information. With the solution of the present invention, the pre-scheduling information is transferred between base stations in various coordinated transmission cells, and the coordinated scheduling/beam-forming is performed according to the pre-scheduling information, thus, the coordinated scheduling/beam-forming is implemented with less amount of information exchange, and the spectrum efficiency of cell-edge terminal is improved.
