1. A communication method, wherein the method is applicable to a wireless communication system, the wireless communication system comprises a first cell, the first cell comprises a plurality of terminal devices that can transmit uplink data on a same uplink time-frequency resource, the plurality of terminal devices comprise a first terminal device, and the method comprises:
determining, by the first terminal device, a reference time domain location based on a preconfigured uplink time-frequency resource, wherein the reference time domain location is the same as a reference time domain location determined by another terminal device in the plurality of terminal devices, wherein the reference time domain location is a time domain location before a start time domain location of the preconfigured uplink time-frequency resource in a periodicity of the preconfigured uplink time-frequency resource;
determining, by the first terminal device, a time domain location that is (first duration×N+second duration×(N−1)) away from the reference time domain location as a start time domain location of X gaps, wherein N is 1, 2, 3, 4, . . . , X, wherein none of the X gaps is used to send uplink data, and X is a positive integer;
determining, by the first terminal device, a time domain location that is (first duration×(M−1)+second duration×(M−1)) away from the reference time domain location as a start time domain location of Y first durations, wherein all or a part of a time domain resource corresponding to at least one of the Y first durations is a time domain resource in a first time-frequency resource used to transmit the uplink data, M is 1, 2, 3, 4, . . . , Y, and Y=X or Y=X+1; and
sending, by the first terminal device, uplink data to a network device on the first time-frequency resource.
