Abstract: 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.
