BASE STATION APPARATUS FOR MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to a base station device of a mobile communication system comprising an antenna system having a first antenna transmitting and receiving a signal with respect to a first path among MIMO paths and a second antenna transmitting and receiving a signal with respect to a second path; a first duplexer having a transmission filter processing a transmission signal of the first path and a reception filter processing a reception signal of the second path; a second duplexer having a reception filter processing a reception signal of the first path and a transmission filter processing a transmission signal of the second path; and a path changing unit providing the transmission signal provided from the first duplexer to the first antenna, providing the reception signal provided from the first antenna to the second duplexer, providing the transmission signal provided from the second duplexer to the second antenna, and providing a signal provided from the second antenna to the first duplexer.
