METHOD AND APPARATUS FOR SUPPORTING POWER HEADROOM REPORT FOR PUSCH RETRANSMISSION USING MULTIPLE TRANSMISSION RECEPTION POINTS IN NEW GENERATION WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2023/204660

Kind Code:

A1

Abstract:

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The method of UE comprises: receiving RRC message comprising cell group configuration information for configuring a first cell group and a second cell group; determining whether a PHR triggering condition is satisfied; determining whether multiple TRPs-based PUSCH repetition related to a serving cell is configured for an arbitrary activated serving cell included in the first cell group and the second cell group, and whether a serving cell group to which the activated serving cell belongs is configured to enable the PHR for the multiple TRPs; obtaining two pieces of power headroom related to the arbitrary activated serving cell; and transmitting a PHR MAC CE comprising the two pieces of power headroom related to the arbitrary activated serving cell to the base station.
