Method of Handling Random Access Procedure on Primary Cell When Random Access Procedure on Secondary Cell is Ongoing or about to Start
First Claim
1. A method of handling a first random access procedure on a primary cell (PCell) for a mobile device when a second random access procedure on a secondary cell (SCell) is ongoing or is about to start, the method comprising:
- selectively initiating the first random access procedure on the PCell according to a result of the second random access procedure after the mobile device completes the second random access procedure on the SCell, wherein the first random access procedure is triggered by a pending scheduling request (SR) of the mobile device and the second random access procedure is triggered by need of synchronization on the SCell.

Abstract
A method of handling a first random access procedure on a Primary Cell (PCell) for a mobile device when a second random access procedure on a Secondary Cell (SCell) is ongoing or is about to start is disclosed. The method comprises selectively initiating the first random access procedure on the PCell according to a result of the second random access procedure after the mobile device completes the second random access procedure on the SCell, wherein the first random access procedure is triggered by a pending scheduling request of the mobile device and the second random access procedure is triggered by need of synchronization on the SCell.

3. A method of handling a first random access procedure on a primary cell (PCell) for a mobile device when a second random access procedure on a secondary cell (SCell) is ongoing, the method comprising:
prohibiting initiating the first random access procedure on the PCell when the mobile device has a pending scheduling request (SR) and is performing the second random access procedure on the SCell, wherein the second random access procedure is triggered by need of synchronization on the SCell.

4. A method of handling a first random access procedure on a primary cell (PCell) for a mobile device when a second random access procedure on a secondary cell (SCell) is ongoing or is about to start, the method comprising:
aborting the second random access procedure on the SCell when the mobile device initiates the first random access procedure on the PCell, wherein the second random access procedure is triggered by need of synchronization on the SCell and the first random access procedure is triggered by a pending scheduling request (SR) of the mobile device. - View Dependent Claims (5)

6. A method of handling a first random access procedure on a primary cell (PCell) for a mobile device when a second random access procedure on a secondary cell (SCell) is ongoing or is about to start, the method comprising:
delaying the second random access procedure on the SCell until the mobile device completes the first random access procedure on a PCell, wherein the second random access procedure is triggered by need of synchronization on the SCell and the first random access procedure is triggered by a pending scheduling request (SR) of the mobile device. - View Dependent Claims (7, 8)
