Title:
ASSOCIATION OF TRANSMISSION CONFIGURATION INDICATORS AND PRECODERS IN UPLINK TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2021/164691
Kind Code:
A1
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that indicates a first transmission configuration indicator (TCI), a second TCI, and a precoding matrix. The first TCI may be associated with a first set of antenna indices of the precoding matrix and the second TCI may be associated with a second set of antenna indices of the precoding matrix. The UE may transmit an uplink transmission based at least in part on the DCI. Numerous other aspects are provided.
