Title:
METHOD OF TRANSMITTING/RECEIVING SIGNAL FOR RANDOM ACCESS CHANNEL PROCEDURE BY TERMINAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/197187
Kind Code:
A1
Abstract:
The present disclosure provides a method of transmitting/receiving a signal for a random access channel procedure (RACH procedure) by a terminal in a wireless communication system. Specifically, the method may comprise: receiving a synchronization signal/physical broadcast channel block (SS/PBCH block); acquiring system information from a PBCH included in the SS/PBCH block; transmitting message A including a physical uplink shared channel (PUSCH) and a physical random access channel (PRACH) preamble on the basis of the system information; and receiving message B including contention resolution information as a response to message A, wherein information associated with retransmission of message A is included in a medium access control protocol data block (MAC PDU) for a random access response (RAR) relating to message B.
