Abstract:
1. A communication system comprising: a slave base station configured to communicate with a core network indirectly through a master base station, the master base station communicating with the core network and controlling a cell in a cellular network, the slave base station controlling at least a portion of the cell, wherein the slave base station comprises: a first transceiver configured to communicate data between the slave base station and the master base station; a second transceiver configured to communicate air interface vector data between the slave base station and a radio resource unit (RRU); and a processor functionally connected to the first transceiver and the second transceiver, the processor configured to perform Layer 1 or Layer 2 processing on the data communicated between the slave base station and the master base station to obtain the air interface vector data communicated between the slave base station and the RRU, or vice versa, wherein the RRU is a network device positioned in-between the slave base station and a terminal, wherein the second transceiver is configured to either send the air interface vector data to the terminal indirectly through the RRU or to receive the air interface vector data from the terminal indirectly through the RRU, wherein the air interface vector data is converted into the uplink data by the processor.
