DYNAMIC SCHEDULING REQUEST FRAMEWORK FOR HP UE SAR REDUCTION

Abstract: a dynamic scheduling request framework reduces the need of a user equipment (ue) to reduce peak transmit power when approaching the specific absorption rate (sar) limit. this preserves the ability of ues to overcome interference (e.g., when near a cell edge), reducing dropped calls, and retains the advantages of high power ues (hp ues), such as power class 2 (pc2) devices. when the combination of the current buffer status report (bsr), indicating more data to transmit, with the current peak transmit power and historical average transmitted power indicates a risk that the ue will violate the sar limit, logic in the ue and/or the network reduces the number of resource blocks (rbs) allocated to the ue. by dropping the duty cycle of the transmitter, even while retaining the current peak transmit power, the average transmitted power will drop. upon the sar violation risk abating, the rb allocation returns to normal.
