Title:
METHOD AND APPARATUS FOR PERFORMING UPLINK POWER CONTROL AND UPLINK CHANNEL TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2021/256882
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to uplink power control and uplink channel transmission, and provide a method for determining uplink channel power control groups, a method for uplink power control, a method for transmitting uplink channel transmissions, and a user equipment. The method for performing of the uplink power control comprises: receiving at least one control information; grouping at least one uplink channel transmission into at least one uplink channel power control group based on at least one information regarding power control included in the received control information, wherein transmission power of uplink channel transmissions included in one of the at least one uplink channel power control group are set to be same; and adjusting power of the at least one uplink channel power control group based on accumulated values of closed-loop power control corresponding each uplink channel power control group.
