Embodiment Construction

[0047] A UE may be enabled for VoLTE or other packet-based operation, enabling the UE to transmit voice information in packets (eg, over an LTE channel). A UE may include an audio layer and a packet layer. The audio layer can encode and decode voice information, and the UE can use the packet layer to send encoded voice information as packets over LTE. The audio layer may encode speech information into packets during an audio layer compression / decompression (codec) period for transmission by the packetization layer. When the voice information is ready for transmission, the audio layer may send voice packets to the packetization layer for transmission by the packetization layer. The packetization layer can be configured on a DRX cycle basis, where the UE wakes up periodically to check for pending data transfers, and then goes back to sleep after processing any pending data transfers until the next DRX cycle. The UE's audio layer and packet layer may operate asynchronously. Fo...

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 anddecode 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 obtainthe 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 voiceinformation 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 beginningof the DRX cycle. The packet layer may extend the wake period to transmit the voice packets.

Description

[0001] cross reference [0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 62 / 533,559, filed July 17, 2017, by Zhou et al., entitled "Voice OverInternet Protocol Power Conservation Techniques for Wireless Systems," and Zhou et al., October 2017 Priority to U.S. Patent Application No. 15 / 722,947, filed on 2 July, entitled "Voice OverInternet Protocol Power Conservation Techniques for Wireless Systems," each of which has been assigned to the assignee of the present application . technical field [0003] The following relates generally to wireless communications and, in particular, to Voice over Internet Protocol power saving techniques for wireless systems.
