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.
