Communication system, method and device

摘要

A communication system and method are provided. The communication system includes a master base station, a slave base station and a remote radio unit (RRU); where a cell controlled by the slave base station is included in cells controlled by the master base station. The master base station is configured to receive downlink data and send the downlink data to the slave base station; and the slave base station corresponds to a transmission channel identifier of the downlink data. The slave base station is configured to receive the downlink data sent by the master base station, convert the downlink data into air interface downlink vector data, and send the air interface downlink vector data to the RRU. The RRU is configured to convert the air interface downlink vector data into analog data and send the analog data to a user equipment, thereby realizing data transmission.

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.
