| Zusammenfassung: | The invention discloses a frequency offset pre-compensation method and device, and the method comprises the steps of obtaining a downlink frequency offset estimation value of each terminal in scheduled terminals, and generating a downlink frequency offset pre-compensation value of each terminal; calculating a unified frequency offset compensation value of the scheduled terminal according to the downlink frequency offset pre-compensation value of each terminal; according to a difference value between a downlink frequency offset pre-compensation value of a terminal and the unified frequency offset compensation value, performing frequency offset pre-compensation on downlink data of each terminal in a first type of terminals in a frequency domain, where the first type of terminals are terminals whose difference values exceed a preset interval in the scheduled terminals; and performing frequency offset pre-compensation on downlink data of the scheduled terminal in a time domain according to the unified frequency o |
