Radio unit, baseband processing unit and base station system

摘要

A radio unit configured to connect to a baseband processing unit includes a transformation unit configured to obtain uplink time domain signal data and transform the uplink time domain signal data into uplink frequency domain signal data; and a compression unit configured to compress the uplink frequency domain signal data by using a compression algorithm.

1. A method for processing uplink signal data in a base station system, the base station system comprising a radio unit and a baseband processing unit, the method comprising:
obtaining, in the radio unit, uplink time domain signal data, collecting parameters of the time domain signal data, and estimating a compression ratio of the uplink time domain signal data based on the parameters; transforming the uplink time domain signal data into uplink frequency domain signal data; compressing, in the radio unit, the uplink frequency domain signal data according to a compression mode by using a first compression algorithm; generating a feedback signal indicating an actual compression ratio resulting from compressing the uplink frequency domain signal data; dynamically controlling the compression mode based on a comparison between the actual compression ratio indicated by the feedback signal and the estimated compression ratio; transmitting the compressed uplink frequency domain signal data from the radio unit to the baseband processing unit when the actual compression ratio is greater than or equal to the estimated compression ratio, and transforming the uplink frequency domain signal data back into the uplink time domain signal data and compressing uplink time domain signal data by using a second compression algorithm when the actual compression ratio is less than the estimated compression ratio; and decompressing, in the baseband processing unit, the compressed uplink frequency domain signal data or the compressed uplink time domain signal data.
