Abstract: This application provides a remote interference suppression method and apparatus and a device, and is applied to the communications field, to stagger a symbol location of an interfered uplink symbol, thereby reducing impact of remote interference. In addition, zero-forcing processing is performed in a direction indicated by Q pieces of phase information corresponding to the caused remote interference, to make a signal approximate 0 to suppress the remote interference, thereby reducing the impact of the remote interference. The method includes: a first network device determines that N uplink symbols are interfered with, and then configures, by using a first mapping type of a physical uplink shared channel (PUSCH), one or more symbols other than the N uplink symbols for uplink PUSCH transmission.
