Increasing scheduling request efficiency in a wireless communication system
View Patent ↗An apparatus and method for increasing Scheduling Request efficiency in a wireless communication system includes a step 400 of configuring periodic timing opportunities for sending the scheduling request. A next step 402 includes detecting new data arriving in an empty queue to trigger a scheduling request. A next step 406 includes sending a scheduling request at selected SR opportunities until a response to the scheduling request is generated.
1. A method for increasing Scheduling Request (“SR”) efficiency in a wireless communication system, the method comprising the steps of:
being configured with periodic timing opportunities for sending a scheduling request;
detecting new data arriving in an empty queue to trigger a scheduling request; and
sending a scheduling request at a next scheduling request opportunity and selected subsequent scheduling request opportunities until an SR exit condition is met;
wherein the sending step includes sending the scheduling request at every Yth SR opportunity, wherein Y is an integer;
wherein Y−1 is a logical channel group number of the new data; and
wherein Y is decremented by 1, if possible, for new data that has been queued for more than half of a periodic timing opportunity before a first scheduling request is sent.
2. The method of claim 1 , wherein the SR exit condition is receiving an uplink grant.
3. The method of claim 1 , wherein the SR exit condition is an expiry of a timer.
4. The method of claim 1 , wherein the SR exit condition is reaching a maximum number of scheduling request transmissions.
5. The method of claim 1 , wherein the SR exit condition is triggering a Buffer Status Report since the last transmission of a Buffer Status Report.
