The embodiment of the present application proposes an
uplink transmission method, device and readable storage medium. The
uplink transmission method includes: receiving capability information and a
sounding reference signal (SRS) of a terminal device; normalizing the matrix corresponding to the
mixed beam after weighted superposition of multiple spatial beams based on the capability information and the SRS, and determining a multi-antenna
codebook, wherein the normalization factor used in the normalization makes the total power of the
mixed beam less than or equal to 1; and sending
uplink scheduling information including
precoding information to the terminal device, wherein the
precoding information is determined by the multi-antenna
codebook. By adopting the
codebook normalization factor, the total power of the
mixed beam is made less than or equal to 1, ensuring that the sum of the
precoding coefficient power of each polarization direction in the precoding is not greater than half of the total precoding coefficient power, thus meeting the requirements of the communication standard.
