Apparatus and method for controlling communication path between multiple digital units and multiple radio frequency units in wireless communication system

摘要

The present invention relates to a communication path control apparatus for controlling a communication path between a plurality of DUs and a plurality of RFUs, and a plurality of antennas included in the plurality of RFUs and a wireless communication system including the communication path control apparatus. Each of the plurality of DUs, the plurality of RFUs, and the plurality of antennas has a unique identifier, and the path control apparatus controls paths between the plurality of DUs and the plurality of RFUs based on identifiers. Accordingly, the wireless communication system can transmit and receive a signal through a specific RFU and a specific antenna included in a specific RFU and performs the next-generation wireless BS operation method, such as CoMP and multi-BS MIMO.
