Abstract
A communication method, an apparatus, and a system for determining, by a first terminal device, a reference time domain position based on a preconfigured uplink time-frequency resource, where the reference time domain position is the same as a reference time domain position determined by another terminal device in a plurality of terminal devices, and the reference time domain position is used to initialize a first sequence; generating, by the first terminal device, a first reference signal based on the first sequence and a time interval, where the time interval is an interval between the reference time domain position and a start time domain position of transmission of the first reference signal; and sending, by the first terminal device, the first reference signal to a network device.
