Temporal power control system and method

Systems and methods are described for reducing processing time of messages that are repeatedly received, with increasing frequency, by a device (e.g., user equipment, base station etc.). For example, the systems and methods would have a base station decrease power, possibly to minimum power-out, per policy, if messages beyond the original are received and the time between those messages is decreasing. The decrease in time between messages indicates a more urgent need for the base station to power down. The systems and methods can be adapted for different types of messages (e.g., power-up, power-down, resource request, bandwidth request, service type, call type origination, quality-of-service request, application type, etc.). Each message type is associated with a policy (pre-determined or adaptive) that indicates the default behavior when the method detects a decrease in time between messages.

Dynamic configuration of operation power parameters

Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.
