Title:
METHOD BY WHICH TERMINAL TRANSMITS/RECEIVES SIGNAL FOR PERFORMING RANDOM ACCESS CHANNEL PROCEDURE IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/033946
Kind Code:
A1
Abstract:
Disclosed is a method by which a terminal transmits/receives a signal for performing a random access channel (RACH) procedure in a wireless communication system. Particularly, the method transmits message A, which includes a physical random access channel (PRACH) and a physical uplink shared channel (PUSCH), and receives message B, which is related to a contention resolution, in response to message A, and transmission power for retransmission of message A is set on the basis of the increase or maintenance of a counter related to the transmission power, the value of the counter is maintained on the basis that a transmission spatial filter related to the PRACH is changed for retransmitting message A, and the counter can be used in setting the transmission power on the basis of the transmission of the PRACH and the PUSCH through message A.
