METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN MULTI-CELL COOPERATIVE COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

The present invention relates to a method for transmitting and receiving signals in a wireless communication system. Specifically, in a multi-cell cooperative communication system, a base station can form cooperative detection user set information by detecting a terminal within a cell and form cooperative processing user set by receiving the cooperative detection user set information of a neighboring base station. At this time, the base station acquires information about a base station adjacent to the neighboring base station and designs an efficient filter in transmitting and receiving signals of terminals between the base stations, thereby being capable of removing inter-cell interference signals.

主权项

1. A method for receiving a signal by a base station (BS) for use in a wireless communication system, comprising:
generating, by a first BS, cooperative detection user equipment (UE) set information by searching for a UE contained in a cell of the first BS; acquiring, by the first BS, cooperative detection UE set information detected by a second BS, from the second BS, wherein the second BS is at least one cooperative BS adjacent to the first BS; updating cooperative processing UE set information of the first BS based on the cooperative detection UE set information detected by the first BS and the cooperative detection UE set information acquired from the second BS; updating, by the first BS, a cooperative processing cell set of the first BS based on the cooperative processing UE set information; and receiving, by the first BS, a signal from a UE located in a cell of the first BS, based on the updated cooperative processing UE set information and the updated cooperative processing cell set information, wherein the updating of the cooperative processing cell set information of the first BS is performed by acquiring third BS information contained in the cooperative processing UE set information, and the third BS being at least one cooperative BS adjacent to the second BS.
