Abstract

The present disclosure provides a method for processing carrier activation at user equipment (UE) and a corresponding device. The method implemented at the user equipment comprises: acquiring an indication related to deactivation of a currently activated carrier, wherein the carrier is a carrier in a carrier group consisting of a plurality of carriers; and if a random access procedure is ongoing, then ignoring the indication.

Claims (15)

1. A method performed by a Medium Access Control (MAC) entity of a user equipment (UE), the method comprising:

stopping a BWPinactivitytimer if a random access procedure is initiated;

starting the BWPinactivitytimer upon successful completion of the Random Access procedure on an active BWP, wherein the active BWP is not a default BWP; and

switching to the default BWP if the BWPinactivitytimer expires.

2. A user equipment (UE) comprising:

a processor; and

a memory, wherein the memory stores instructions that cause the processor to:

cause a Medium Access Control (MAC) entity of the UE to stop a BWPinactivitytimer, if a random access procedure is initiated;

cause the MAC entity to start the BWPinactivitytimer, upon successful completion of the Random Access procedure on an active BWP, wherein the active BWP is not a default BWP; and

cause the MAC entity to perform switching to the default BWP, if the BWPinactivitytimer expires.

3. The method according to claim 1 , wherein the BWPinactivitytimer stopped when the Random Access procedure is initiated remains stopped until the successful completion of the Random Access procedure.

4. The UE according to claim 2 , wherein the BWPinactivitytimer stopped when the Random Access procedure is initiated remains stopped until the successful completion of the Random Access procedure.

5. The UE according to claim 2 , wherein

the active BWP is configured for a primary cell, and

the default BWP is configured for the primary cell.
