Title:
METHOD FOR PERFORMING A RANDOM ACCESS PROCEDURE IN BANDWIDTH PART (BWP) OPERATION IN WIRELESS COMMUNICATION SYSTEM AND A DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/083245
Kind Code:
A1
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a random access procedure in BWP operation in wireless communication system, the method comprising: starting a timer related to timing alignment of a Timing Advance Group (TAG) to which a serving cell belongs; switching an active Downlink (DL) Bandwidth Part (BWP) of the serving cell from a first DL BWP to a second DL BWP, when the timer expires; and monitoring a downlink control channel on the second DL BWP.
