Title:
COMMUNICATION METHOD AND DEVICE FOR REDUCED-CAPABILITY UE IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/039406
Kind Code:
A1
Abstract:
An efficient communication method and device for a Reduced-capability UE using a half-duplex communication scheme in a wireless communication system. According to an embodiment, a method for performing a random access procedure by a reduced-capability user equipment (UE) in a wireless communication system comprises receiving, from a base station, configuration information including resource information for random access by the Reduced-capability UE, identifying whether there is a random access occasion overlapping a radio frequency (RF) switching gap in a time domain when the random access is performed, and when there is the random access occasion overlapping the RF switching gap, performing the random access procedure with the base station on a next random access occasion except for the overlapping random access occasion, based on the received resource information for random access.
