1. An uplink scheduling information determining method, comprising:
reporting, by user equipment, a full power transmission capability of the user equipment and/or a coherent transmission capability of the user equipment to a base station;
determining, by the user equipment, a codebook subset of a codebook-based physical uplink shared channel, PUSCH, and/or second information according to first information; wherein
the first information comprises at least one of the full power transmission capability, and a first instruction, or,
the first information comprises the coherent transmission capability, and at least one of the full power transmission capability, and a first instruction;
the second information comprises an overhead of the indication of precoding information and number of transmission layers of the codebook-based PUSCH, and/or an encoding mechanism of the indication of precoding information and number of transmission layers of the codebook-based PUSCH; the first instruction comprises an instruction for indicating a full power transmission mode; and;
receiving, by the user equipment, uplink scheduling information of the codebook-based PUSCH sent by the base station; and
determining, by the user equipment, the precoding matrix and the number of transmission layers of the codebook-based PUSCH according to the uplink scheduling information of the codebook-based PUSCH and the second information sent by the base station.
