Abstract: This application provides a symbol processing method and apparatus. The method includes: obtaining a plurality of complex-valued symbols; dividing the plurality of complex-valued symbols into a plurality of sets, where each set corresponds to one transmitted symbol; and performing a copy operation on the plurality of sets, so that two sets corresponding to two transmitted symbols that are consecutive in time domain have some same complex-valued symbols. By enabling two sets corresponding to two transmitted symbols that are consecutive in time domain to have some same complex-valued symbols, a guard interval between symbols can be flexibly configured when a cyclic prefix length is fixed.

Abstract: This application provides a symbol processing method and apparatus. The method includes obtaining, based on a plurality of complex-valued symbols, a first set corresponding to a first transmitted symbol and a second set corresponding to a second transmitted symbol, performing a copy operation on the first set and the second set so both the first set and the second set have first complex-valued symbols, and a first subset start location including the first complex-valued symbols in the first set is the same as a second subset start location including the first complex-valued symbols in the second set; and performing signal processing including a cyclic shift or frequency domain weighting on the first set and the second set. The start location and an end location of the first subset respectively correspond to locations preceding and following a first reference point of the first transmitted symbol.

Abstract: This application discloses a resource unit setting method, a resource unit transmission method, and an apparatus. The method includes: setting, by a transmit end device based on a setting threshold of a null resource unit and/or a scheduling parameter, a plurality of null resource units at time domain and/or frequency domain locations associated with phase tracking reference signal resource units of one or more OFDM symbols; and sending, by the transmit end device, the one or more OFDM symbols. The corresponding apparatus is further disclosed. In the technical solution of this application, the null resource unit is set based on the setting threshold of the null resource unit and/or the scheduling parameter. Demodulation accuracy of a high-frequency communications system is ensured, and overheads of the null resource unit are as low as possible, thereby improving spectrum efficiency.
