METHOD AND APPARATUS FOR PROCESSING UPLINK FREQUENCY SHIFT OF COMMUNICATION SYSTEM

摘要

Disclosed are a method and apparatus for processing an uplink frequency offset of a communication system. The method at a base station side comprises: demodulating a random access message sent by a terminal to obtain an initial Doppler frequency offset of the terminal and issue same to the terminal; receiving an uplink subframe signal sent by the terminal, estimating a residual Doppler frequency offset of the terminal at an uplink, obtaining a frequency adjustment amount according to the residual Doppler frequency offset and issuing same to the terminal. The method at the terminal side comprises: receiving an initial Doppler frequency offset sent by a base station, and obtaining an initial transmission frequency of an uplink and sending an uplink subframe signal according to an initial transmission frequency and an initial Doppler frequency offset of a downlink; and receiving a frequency adjustment amount sent by the base station, and obtaining the next transmission frequency of the uplink according to the frequency adjustment amount.
