    Abstract: A transmit end determines M first time-frequency resource locations and S second time-frequency resource locations, and determines, in the S second time-frequency resource locations, S/2 second time-frequency resource locations as a first set, and S/2 second time-frequency resource locations excluding the second time-frequency resource locations in the first set as a second set; determines a communication data symbol sent at the second time-frequency resource locations in the first set; obtains, a compensation data symbol sent at the second time-frequency resource locations in the second set, where interference of the communication data symbol to the pilot data symbol cancels out interference of the compensation data symbol to the pilot data symbol; and separately sends the pilot data symbol at the M first time-frequency resource locations, and sends the communication data symbol and the compensation data symbol at the S second time-frequency resource locations.
