Abstract: A method and device for scheduling SR transmissions for a user equipment (UE) associated with an evolved Node B (eNB) of a Long Term Evolution (LTE) network. The method includes determining an SR is to be transmitted to the LTE network, determining an uplink grant behavior of the eNB, when the uplink grant behavior of the eNB indicates that previous uplink grants satisfy a threshold of previous grants occurring in onDurations of the cycle of a C-DRX functionality, selecting one of the at least one SR opportunity that follows a next onDuration relative to when the indication is received and scheduling the SR in the one of the at least one SR opportunity that follows the next onDuration. The method further including determining an uplink grant turnaround time associated with the eNB, and selecting one of the at least one SR opportunity based on the uplink grant turnaround time.

Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using multiplexing at a layer above the physical layer. The wireless device may establish wireless links with first and second base stations, respectively, according to first and second radio access technologies (RATs), respectively. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether inter-RAT uplink coexistence in the same frequency band is enabled. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth by multiplexing uplink data for the first RAT and uplink data for the second RAT at a layer above the physical layer.

Abstract: QoS based uplink data buffering while TTI bundling is enabled by a wireless user equipment (UE) device. The UE may establish a packet-switched connection with a network via a wireless link. The UE may receive, at a media access control (MAC) layer, an indication to enable TTI bundling. The UE may selectively buffer uplink data at an application layer based on the indication to enable TTI bundling. The uplink data may be buffered selectively based on Quality of Service (QoS) considerations. Uplink transmissions may subsequently be performed using TTI bundling.

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。
