Scheduling request (sr) period extension for low power enhancement in a wireless communication device

A wireless communication device, comprising circuitry configured to:

• receive a discontinuous reception (DRX) configuration specifying a DRX having a DRX cycle;
• receive an original scheduling request (SR) configuration specifying an original sequence of SR transmission opportunities having an original SR period;
• select an extended SR period corresponding to an extended sequence of SR transmission opportunities according to the DRX cycle, the extended SR period being a multiple of the original SR period and corresponding to a set of candidate SR offsets;
• determine for each of the set of candidate SR offsets an overlap between active times caused by the DRX and active times caused by SR transmissions at each of the extended sequence of SR transmission opportunities;
• and
• select one of the SR offsets having a largest overlap from the set of the candidate SR offsets to determine a period-extended SR configuration including the selected extended SR period and the selected SR offset.

A non-transitory computer readable medium storing program instructions that, when executed by a processor, cause the processor to perform a method for reducing power consumption of a wireless communication device, the method comprising:

• receiving a discontinuous reception (DRX) configuration specifying a DRX having a DRX cycle;
• receiving an original scheduling request (SR) configuration specifying an original sequence of SR transmission opportunities having an original SR period;
• selecting an extended SR period corresponding to an extended sequence of SR transmission opportunities according to the DRX cycle, the extended SR period being a multiple of the original SR period and corresponding to a set of candidate SR offsets;
• determining for each of the set of candidate SR offsets an overlap between active times caused by the DRX and active times caused by SR transmissions at each of the extended sequence of SR transmission opportunities;
• and
• selecting one of the SR offsets having a largest overlap from the set of the candidate SR offsets to determine a period-extended SR configuration including the selected extended SR period and the selected SR offset.
