Title:
METHOD AND APPARATUS FOR BEAM INDICATION WITH A DL-RELATED DCI FORMAT
Document Type and Number:
WIPO Patent Application WO/2022/186643
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses for beam indication with a downlink (DL)-related downlink control information (DCI) format in a wireless communication system. A method of operating a user equipment (UE) includes receiving configuration information for a list of transmission configuration indication (TCI) states; receiving TCI state code points activated via a medium access control-control element (MAC CE); and receiving a downlink control information (DCI) format indicating at least one of the activated TCI state code points. The DCI format does not include a downlink (DL) assignment and includes fields set to a bit pattern. The method further includes determining a TCI state to apply based on the at least one indicated TCI state code point; updating, based on the determined TCI state, quasi-co-location (QCL) assumption or spatial filters; and at least one of receiving based on the updated QCL assumption and transmitting based on the updated spatial filters.
