FULL-DUPLEX TRANSMISSION IN A MULTI-CARRIER COMMUNICATION SYSTEM

摘要

Embodiments of the present invention disclose a transmission method and apparatus. The method includes: receiving, by a receiver, a communication signal, where the communication signal includes an uplink signal and a downlink signal that are transmitted on a same time-frequency resource, the uplink signal and the downlink signal use a same carrier mapping manner, the uplink signal corresponds to a first multiple access manner, and the downlink signal corresponds to a second multiple access manner; and performing, by the receiver, interference cancellation on the communication signal according to the first multiple access manner and the second multiple access manner. In the embodiments of the present invention, an uplink signal and a downlink signal that are transmitted on a same time-frequency resource use a same carrier mapping manner. In this way, after a new technology is introduced, a problem that carrier mapping manners of an uplink signal and a downlink signal that are on a same time-frequency resource are different can be overcome, which helps a receiver of a communication signal perform interference cancellation.
