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 a transmission signal provided from the first duplexer to the first antenna, providing a reception signal provided from the first antenna to the second duplexer, providing a transmission signal provided from the second duplexer to the second antenna, and providing a signal provided from the second antenna to the first duplexer.
