Title:
UPLINK TRANSMISSION METHOD AND APPARATUS, DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/272514
Kind Code:
A1
Abstract:
The present disclosure relates to the field of communications, and provides an uplink transmission method and apparatus, a device, and a readable storage medium. The method comprises: receiving configuration signaling, the configuration signaling comprising a first indication field, and the first indication field being used for indicating precoding matrix indicator information, i.e., TPMI indication information when a terminal sends codebook-based uplink transmission of a physical uplink shared channel (PUSCH); and determining, on the basis of the TPMI indication information, precoding used when the PUSCH is sent, wherein the terminal reports whether to support the capability of a second TPMI indication field. In PUSCH transmission, a configurable uplink transmission solution is considered, the overhead of DCI signaling caused by TPMI is reduced by using a macrodiversity method, and the robustness during uplink repeated transmission is enhanced.
