Abstract: PURPOSE: A cooperative communication method in a sub band between multi nodes based on long term channel information and a device thereof are provided to set the priority of a base station in a sub band and perform scheduling in a sub band based on the set priority. CONSTITUTION: A scheduler(1420) schedules how to use each sub band of a target base station. The scheduler generates scheduling information for the target base station. An information exchange unit(1430) transmits the scheduling information of the target base station to at least one adjacent base station at every set cycle. The information exchange unit receives scheduling information for the adjacent base station. A re-scheduler(1440) schedules each sub band based on the scheduling information of the target base station and the scheduling information of the adjacent base station.

Abstract: PURPOSE: A multi I/O communication system using a codebook and a design method of the codebook are provided to use limited feedback resources more efficiently. CONSTITUTION: A multi I/O communication system calculates an intrinsic vector matrix including a channel matrix or the eigenvectors or a channel covariance matrix(210,220,230).
