Abstract: Some embodiments relate to a user equipment device (UE), and associated methods for enabling the UE to estimate motion of the UE based on cell type. In some embodiments, in response to determining that a serving cell of the UE is not a macro cell, a motion estimation algorithm may be disabled for at least a first time period and when the first time period lapses, the motion estimation algorithm may be partially enabled to estimate speed of the UE for at least a second time period. In response to the speed of the UE remaining above a speed threshold for at least the second time period, the motion estimation algorithm may be fully enabled. In response to the speed of the UE not remaining above the speed threshold for at least the second time period, the motion estimation algorithm may be disabled for at least a third time period.

Abstract: A method for reducing scheduling requests by a wireless communication device transmitting data using dynamically scheduled resources over a logical channel is provided. The method includes receiving, at the wireless communication device, a configuration from a network entity that sets a LogicalChannelSR-Mask for a logical channel for which uplink resources can be dynamically scheduled by the wireless network. The method further includes waiting to send a scheduling request (SR) for a delay time period when data is available to be sent on the logical channel and uplink resources have not been granted. The method additionally includes using the grant to send the data without sending an SR when a grant is received within the delay time period; or sending an SR when a grant is not received within the delay time period. In another method, a network selectively enables or disables SRs for a logical channel through explicit signaling.

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。
