Title:

METHOD AND APPARATUS FOR HANDLING BWP SWITCHING IN RANDOM ACCESS PROCEDURE

Document Type and Number:

WIPO Patent Application WO/2020/088610

Kind Code:

A1

Abstract:

A method for random access performed by a MAC entity of a UE is provided. The method includes: receiving a first beam failure recovery configuration of a first UL BWP; receiving a second beam failure recovery configuration of a second UL BWP; initiating a first RA procedure on the first UL BWP by applying at least one first RA parameter configured in the first beam failure recovery configuration, when a number of beam failure instances that haves been received from lower layers is larger than or equal to a threshold; switching an active UL BWP of the UE from the first UL BWP to a second UL BWP before completion of the first RA procedure; and initiating a second RA procedure on the second UL BWP by applying at least one second RA parameter configured in the second beam failure recovery configuration, after switching to the second UL BWP.
