1. A method for determining a codebook subset, comprising:
receiving, by a user equipment (UE), first indication information from a network device, wherein the first indication information is used to indicate a first sounding reference signal (SRS) resource in an SRS resource set; and
receiving, by the UE, second configuration information from the network device, wherein the second configuration information is used to configure the SRS resource set, the SRS resource set comprises one or a plurality of SRS resources, and the SRS resource set is configured to support full power transmission; and wherein when the SRS resource set comprises the plurality of SRS resources, each of the plurality of SRS resources is configured to have a number of antenna ports as same as or different from that of one another;
receiving, by the UE, first configuration information from the network device, wherein the first configuration information is used to configure codebook subsets; and
determining, by the UE, the first SRS resource in the SRS resource set based on the first indication information and the second configuration information; and when the first SRS resource has two antenna ports, determining, by the UE, that the codebook subset for uplink transmission is ‘nonCoherent’ if the first configuration information is set to ‘partialAndNonCoherent’.
