Title:
METHOD AND APPARATUS FOR REDUCING BANDWIDTH PART SWITCHING DELAY TIME IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/014187
Kind Code:
A1
Abstract:
The present disclosure provides a BWP switching method performed by a terminal in a wireless communication system. The method comprises the steps of: identifying a first bandwidth part (BWP) associated with a first communication direction and a plurality of BWPs associated with a second communication direction, the plurality of BWPs associated with the second communication direction including a second BWP and a third BWP having a bandwidth size greater than a bandwidth size of the second BWP, and center frequencies of the first BWP and the third BWP being same; receiving information indicating switching from the first BWP to the second BWP; and switching from the first BWP to the second BWP on the basis of the information, wherein a guard period required for the switching from the first BWP to the second BWP is determined on the basis of whether center frequencies of the second BWP and the third BWP are same and whether the second BWP and the third BWP overlap in a frequency domain.
