Abstract
A method and device are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE triggering a Beam Failure Recovery (BFR) associated with a cell. The method also includes the UE triggering a Scheduling Request (SR) for Secondary Cell (SCell) beam failure recovery in response to the triggered BFR. The method further includes the UE cancelling the triggered BFR and the triggered SR in response to reset of a Medium Access Control (MAC) entity associated with the cell.
Claims20
A method for a User Equipment (UE), comprising:
- triggering a Beam Failure Recovery (BFR) associated with a cell;
- triggering a Scheduling Request (SR) for Secondary Cell (SCell) beam failure recovery in response to the triggered BFR when no Uplink Shared Channel (UL-SCH) resources are available for accommodating a BFR Medium Access Control (MAC) Control Element (CE) plus its subheader;
- and
- cancelling the triggered BFR and the triggered SR in response to reset of a Medium Access Control (MAC) entity associated with the cell.

A User Equipment (UE), comprising:
- a control circuit;
- a processor installed in the control circuit;
- and
- a memory installed in the control circuit and operatively coupled to the processor;
- wherein the processor is configured to execute a program code stored in the memory to:
- trigger a Beam Failure Recovery (BFR) associated with a cell;
- trigger a Scheduling Request (SR) for Secondary Cell (SCell) beam failure recovery in response to the triggered BFR when no Uplink Shared Channel (UL-SCH) resources are available for accommodating a BFR Medium Access Control (MAC) Control Element (CE) plus its subheader;
- and
- cancel the triggered BFR and the triggered SR in response to reset of a Medium Access Control (MAC) entity associated with the cell.
