Abstract: This application provides a signal processing method and a related apparatus. The method is applied to a network device and includes: receiving sounding signal information from user equipment, where the sounding signal information includes N pieces of sub-sounding signal information received by N antennas of the network device; performing first weighting processing on the sounding signal information based on a first matrix to determine first signal information; determining a channel weight of to-be-sent signal information based on the first signal information, and weighting the to-be-sent signal information based on the channel weight, to determine N pieces of second signal information; performing second weighting processing on the N pieces of second signal information based on a second matrix to obtain N pieces of third signal information, where the second matrix is an inverse matrix of the first matrix; and sending the corresponding third signal information using the N antennas.

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.
