RADIO UNIT, BASEBAND PROCESSING UNIT, BASE STATION SYSTEM COMPRISING THESE, AND METHOD FOR PROCESSING SIGNAL DATA IN THE SYSTEM (RADIO UNIT, BASEBAND PROCESSING UNIT, AND BASE STATION SYSTEM)

摘要

PROBLEM TO BE SOLVED: To provide a base station system that reduces data traffic and communication bandwidth pressure between a radio unit and a baseband processing unit.SOLUTION: A remote radio unit comprises: a transformation unit to obtain uplink time domain signal data and transform it into uplink frequency domain signal data; a compression unit to compress the uplink frequency domain signal data by using a compression algorithm; a decompression unit to obtain compressed downlink signal data from a baseband processing unit and decompress the same; and an inverse transformation unit to obtain downlink time domain signal data by inversely transforming the decompressed downlink signal data. The baseband processing unit comprises a decompression module for uplink data and a compression module for downlink data.
