Micro-idle power in a subsystem of a portable computing device may be actively managed based on client voting. Each client vote may include a client activity status indication and a client latency tolerance indication. Votes are aggregated to provide an aggregate client latency tolerance, which may be used to obtain a set of micro-idle time values. Micro-idle timers in the subsystem may be set to associated micro-idle time values. The micro-idle timers determine whether one or more of the micro-idle time values have elapsed. A power management policy associated with each micro-idle time value determined to have elapsed may be applied to a portion of the subsystem.

Active power management in a computing device subsystem based on micro-idle duration

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be enabled for voice over long term evolution (VoLTE). The UE may include an audio layer to encode and decode voice information and a packet layer to transmit voice packets. The packet layer may store parameters related to a discontinuous reception (DRX) in a shared memory. The audio layer may obtain the DRX parameters and encode voice information based on the parameters. For example, the audio layer coding may be synchronized with the wake period of the DRX cycle. The audio layer may encode voice information during a wake up period of the packet layer DRX cycle, and the packet layer may transmit the voice packets while awake. The audio layer may perform back to back encodings at the beginning of the DRX cycle. The packet layer may extend the wake period to transmit the voice packets.
