Title:
RANDOM ACCESS PROCEDURE METHOD FOR TERMINAL IN WIRELESS COMMUNICATION SYSTEM SUPPORTING UNLICENSED BAND, AND DEVICES SUPPORTING SAME
Document Type and Number:
WIPO Patent Application WO/2020/060315
Kind Code:
A1
Abstract:
The present document discloses a random access procedure method for a terminal in a wireless communication system supporting an unlicensed band, and devices supporting same. As specific examples, the present document includes operation examples of a method for determining various parameters (e.g. a random access network temporary identifier (RA-RNTI), an RA resource, a PRACH preamble index, etc.) for transmitting a physical random access channel (PRACH) preamble on an unlicensed band, and a terminal and a base station based on same.
