Abstract

What is disclosed is a method of operating a wireless communication device, where a wireless access node provides wireless access to communication services over a wireless link for the wireless communication device. The method includes transferring data in a series of frames to the wireless access node over a reverse link portion of the wireless link, where each frame comprises a series of subframes, and transferring a present frame at a first power level. The method also includes, during transfer of the present frame at the first power level, monitoring control information transferred by the wireless access node on a forward link portion of the wireless link, and in response to receiving a power change instruction in the control information, interrupting transfer of the subframes of a present frame at the first power level and restarting transfer of the subframes of the present frame at a second power level.

Dependent claims

A method of operating a wireless communication device, wherein a wireless access node provides wireless access to communication services over a wireless link for the wireless communication device, the method comprising:

transferring data in a series of frames to the wireless access node over a reverse link portion of the wireless link, wherein each frame comprises a series of subframes;
transferring a present frame at a first power level;
during transfer of the present frame at the first power level, monitoring control information transferred by the wireless access node on a forward link portion of the wireless link;
in response to receiving a power change instruction in the control information during transfer of a final subframe of the present frame at the first power level, continuing transfer of the final subframe of the present frame at the first power level;
and
in response to receiving the power change instruction in the control information during transfer of a non-final subframe of present frame at the first power level, interrupting transfer of the subframes of the present frame and restarting transfer of the subframes of the present frame at a second power level.

A wireless communication device, wherein a wireless access node provides wireless access to communication services over a wireless link for the wireless communication device, comprising:

a transceiver configured to transfer data in a series of frames to the wireless access node over a reverse link portion of the wireless link, wherein each frame comprises a series of subframes;
the transceiver configured to transfer a present frame at a first power level;
during transfer of the present frame at the first power level, a processing system configured to monitor control information transferred by the wireless access node on a forward link portion of the wireless link;
in response to receiving a power change instruction in the control information during transfer of a final subframe of the present frame at the first power level, the transceiver is configured to continue transfer of the final subframe of the present frame at the first power level and transfer a subsequent frame at the second power level;
and
in response to receiving the power change instruction in the control information during transfer of a non-final subframe of present frame at the first power level, the transceiver is configured to interrupt transfer of the subframes of the present frame and restart transfer of the subframes of the present frame at a second power level.
