Title:
PRECODING MATRICES FOR FULL-POWER UPLINK TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2023/206358
Kind Code:
A1
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a power mode for transmitting eight uplink transmission chains, wherein the power mode is one of a full-power mode or a non-full-power mode, and wherein at least a first set of precoding matrices is associated with the full-power mode and at least a second set of precoding matrices is associated with the non-full-power mode. The UE may receive an indication of a selected precoding matrix, wherein the indication is based at least in part on the configuration of the power mode and one of the first set of precoding matrices or the second set of precoding matrices. The UE may transmit the eight uplink transmission chains based at least in part on the selected precoding matrix. Numerous other aspects are described.
