Classification: CPC H | IPC H

Claim 14:
15. The terminal device of claim 10, wherein the first transceiver is configured to perform at least one of:
determining a codebook subset available for precoding based on codebook subset constraint configuration, determining a precoding matrix used for transmitting the data channel based on the codebook subset and precoding indication information from a network side, and transmitting the data channel based on the determined precoding matrix;
determining a maximum transmission layer number allowed for present data transmission based on configuration of a maximum transmission layer number, determining content of scheduling request indicator/rank indicator (SRI/RI) indication field in the DCI based on the maximum transmission layer number, and transmitting the data channel based on the content of the SRI/RI indication field;
determining, based on transmission configuration of UCI carried by the data channel, a physical resource occupied by the UCI, and transmitting the UCI in the physical resource on the data channel; or,
determining, based on configuration of whether to allow pi/2-BPSK modulation of DFT transformation, whether to perform the DFT transformation on the data channel modulated by the pi/2-BPSK modulation and transmitting the data channel.
