1. A signal processing method, applied to a network device, the method comprising:
determining, by the network device, a plurality of Tracking Reference Signals (TRSs) or Channel State Information-Reference Signals (CSI-RSs) with which a terminal performs frequency estimation;
transmitting, by the network device, each of the plurality of TRSs or CSI-RSs to the terminal through a respective one of a plurality of antenna panels of the network device;
transmitting, to the terminal, first information,
wherein the first information comprises information of association of the plurality of TRSs or CSI-RSs with a plurality of sounding reference signals (SRSs), wherein each of the plurality of SRSs is associated with a respective one of the plurality of TRSs or CSI-RS, and the first information indicates the terminal to adjust a transmission frequency of each of the plurality of SRSs according to frequency information estimated by the terminal based on a respective one of the plurality of TRSs or CSI-RSs,
wherein the frequency information comprises Doppler frequency offset.
