APPARATUS FOR SHARING ANTENNA OF WIRELESS ACCESS NODE IN WIRELESS COMMUNICATION NETWORK

摘要

The present invention provides an apparatus for sharing antennas of wireless access node systems in a wireless communications network including an A-wireless access node system and a B-wireless access node system each having at least one transmission/reception unit for processing a transmission/reception signal of at least one frequency band. The apparatus for sharing antennas of wireless access node systems comprises a MIMO (multiple input multiple output) coupler A and a MIMO coupler B. The MIMO coupler A connects a signal of a first transmission/reception path among MIMO paths of at least one transmission/reception unit in the A wireless access node system and a signal of a second transmission/reception path among MIMO paths of at least one the transmission/reception unit in the B wireless access node system to an antenna of the A-wireless access node system. The MIMO coupler B connects a signal of a first transmission/reception path among the MIMO paths of the at least one transmission/reception unit in the B-wireless access node system and a signal of a second transmission/reception path among the MIMO paths of the at least one transmission/reception unit in the A-wireless access node system to an antenna of the B-wireless access node system.
