Abstract: A station that generates data packets to be transmitted such that the data packets spend a minimum amount of time in a buffer prior to transmission. The method includes receiving a specification for a connected discontinuous reception (C-DRX) cycle that indicates when a plurality of on Durations of the C-DRX cycle occurs, the on Durations having a predetermined interval therebetween, receiving data at a known time relative to the C-DRX cycle, determining a modification to a conversion process that converts the data to data packets such that the data packets are stored in a buffer at a subframe immediately preceding one of the on Durations subsequent to the known time, performing the conversion process based upon the modification and storing the data packets at the subframe immediately preceding the one of the on Durations. In one embodiment, the data is raw audio data and the data packets are audio packets.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract translation: 与包括基站（BS）的网络的连接可以由用户设备（UE）经由无线连接建立，用于使用在连续的不连续接收（C-DRX）模式中的半永久调度（SPS）进行通信。 可以相对于SPS激活命令和SPS间隔UL（对于上行链路）来调整SPS发送周期。 然后可以根据所确定的SPS发送周期在C-DRX持续时间周期期间发送数据。 在一些实施例中，调整SPS发送周期，使得在接收到SPS激活命令之后的第一C-DRX持续时间周期之后，SPS数据传输在每个随后的C-DRX持续时间段期间发生特定数量的子帧 比在第一个C-DRX持续时间段。 一旦UE设备在持续时间期间唤醒，可以在每个随后的C-DRX持续时间段中的SPS数据传输发生。
