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.

Abstract: The present disclosure provides an FBMC-based pilot sending method, a channel estimation method, and a related apparatus. The FBMC-based pilot sending method includes: for each transmit antenna port, inserting a pilot symbol group at four consecutive FBMC time-frequency resource locations, where the pilot symbol group includes two auxiliary pilot symbols and two primary pilot symbols; calculating a transmit value of each auxiliary pilot symbol in the pilot symbol group according to obtained interference coefficient values and obtained transmit values of data symbols at time-frequency resource locations in a time-frequency resource location range in which each primary pilot symbol is interfered with; and sending the pilot symbol group, where the pilot symbol group includes the calculated transmit values of the auxiliary pilot symbols.
