Claim 0:
1. A signal processing method, comprising:
indicating a first uplink sounding reference signal resource to a terminal, wherein the first uplink sounding reference signal resource is used for uplink beam scanning;
receiving an uplink sounding reference signal transmitted by the terminal by using the first uplink sounding reference signal resource;
determining a target uplink sounding reference signal based on the uplink sounding reference signal transmitted by the terminal, and transmitting an identifier of the target uplink sounding reference signal to the terminal;
indicating a second uplink sounding reference signal resource to the terminal, the second uplink sounding reference signal resource being used for the terminal to transmit an uplink sounding reference signal for channel measurement based on the identifier of the target uplink sounding reference signal and the second uplink sounding reference signal resource;
wherein the method further comprises:
transmitting corresponding-relation indication information to the terminal, wherein the corresponding-relation indication information comprises a corresponding relation between the second uplink sounding reference signal resource and the identifier of the target uplink sounding reference signal; or pre-agreeing the corresponding relation between the second uplink sounding reference signal resource and the identifier of the target uplink sounding reference signal with the terminal;
in a case that the corresponding relation is a corresponding relation between identifiers of N uplink sounding reference signals and P second uplink sounding reference signal resources, the corresponding relation is used to indicate to the terminal that uplink beams corresponding to identifiers of ones of N uplink sounding reference signals can be transmitted simultaneously; or
in a case that the corresponding relation is a corresponding relation between identifiers of N uplink sounding reference signals and one second uplink sounding reference signal resource, the corresponding relation is used to indicate to the terminal that uplink beams corresponding to identifiers of the N uplink sounding reference signals can be transmitted simultaneously; or
in a case that the corresponding relation is a corresponding relation between identifiers of N uplink sounding reference signals and N second uplink sounding reference signal resources, the corresponding relation is used to indicate to the terminal that uplink beams corresponding to identifiers of the N uplink sounding reference signals are not transmitted simultaneously.
