Example Embodiment
[0058] The present invention is mainly applied in high-speed mobile scenarios. The basic idea is: First, the base station estimates the frequency offset of the received uplink signal to obtain the terminal k uplink frequency offset estimation result And according to Perform pre-frequency offset compensation on the downlink signal; the terminal detects the frequency of the downlink signal received by itself after the frequency offset compensation, determines the transmission frequency of the uplink signal according to the detected downlink signal frequency, and adjusts its operating frequency to all The determined frequency transmits the uplink signal to the base station at the determined frequency; if the terminal side adopts frequency pre-compensation technology, the method of pre-frequency offset compensation on the terminal side is the same as the method of frequency offset compensation on the base station side.
[0059] The present invention will be further described in deta...
