Abstract

The present invention provides a processing method based on an OFDM-TDMA two-way service and a communications device. The method includes assigning timeslots in a TDMA frame structure to multiple users in a TDMA manner, so that each user has a different timeslot, and each timeslot of the users is simultaneously used for uplink and downlink communication. The methods further includes simultaneously sending a local-end OFDM signal and receiving a remote-end OFDM signal in each timeslot of the users, and cancelling, in an OSD manner, interference caused by an echo OFDM signal, which is produced according to the local-end OFDM signal, to the remote-end OFDM signal, where a spectrum of the echo OFDM signal and a spectrum of the remote-end OFDM signal overlap.
