Abstract: Methods, apparatuses and computer readable media are described that manage transmit power levels for a wireless device connected to a network access system of a wireless network. Processing circuitry in the wireless device obtains a target average transmit power level. Based on estimates of an actual average transmit power level for a sliding window of a past time period and the target average transmit power level, the processing circuitry determines a target transmit power level, a duty cycle percentage, and a transmit pattern of transmit on frames and transmit off frames for a future time period. The processing circuitry sends to the access network system signaling messages indicating non-zero valued buffer status reports for the transmit on frames and zero valued buffer status reports for the transmit off frames. Non-zero values correspond to actual amounts of pending uplink data, while zero values are sent irrespective of actual uplink buffer status.

Abstract: A wireless communication device (UE) may conduct wireless communications using one or more antennas according to multiple radio access technologies (RAT) associated with corresponding operating frequency bands. The UE may perform adaptive antenna tuning, for example, application-based antenna tuning for increasing the operating efficiency of the UE, which may improve user experience. The UE may periodically identify one or more applications running on the UE, the respective RATs that support the (running) applications, and which of the corresponding frequency bands are used by the (running) applications. The UE may determine the tuner device settings for tuning the one or more antenna(s) based on the (running) applications or the type and/or priority of the (running) applications, which RATs support the running applications, which of the corresponding frequency bands are used by the (running) applications, and operating conditions associated with the frequency bands used by the (running) applications.

Abstract: Embodiments described herein relate to an apparatus, system, and method for controlling access to multiple antennas in a mobile device. The mobile device may determine priority among a first protocol stack associated with a first subscriber identity module (SIM) in the mobile device and a second protocol stack associated with a second SIM in the mobile device. The mobile device may lock control of a position of a switch to the first protocol stack based on determining the priority among the first protocol stack and the second protocol stack. The switch may control access to the multiple antennas. Accordingly, the second protocol stack may be unable to modify the position of the switch when control of the switch is locked to the first protocol stack.
Abstract translation: 本文描述的实施例涉及用于控制对移动设备中的多个天线的接入的设备，系统和方法。 移动设备可以确定与移动设备中的第一用户身份模块（SIM）相关联的第一协议栈和移动设备中与第二SIM相关联的第二协议栈的优先级。 移动设备可以基于确定第一协议栈和第二协议栈之间的优先级来锁定对第一协议栈的交换机的位置的控制。 交换机可以控制对多个天线的接入。 因此，当开关的控制被锁定到第一协议栈时，第二协议栈可能不能修改交换机的位置。
