Method and device for processing carrier activation
View Patent ↗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.
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.
