    Abstract: Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. Signal strength measurements may be gathered using the antennas and corresponding signal strength difference measurements may be produced to reflect which of the antennas is exhibiting superior performing. Information may be gathered relating to the fading environment of the communications circuitry, such as whether the wireless communications circuitry is transitioning between a fast fading environment and a slow fading environment. For example, the wireless communications circuitry may further include a satellite positioning system receiver or an accelerometer, which may be used in gathering the information. The difference measurements may be filtered and compared to antenna switching criteria such as antenna switching thresholds. An antenna switching threshold may be adjusted in real time based at least in part on the gathered information.

    Abstract: A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.

    Abstract translation: 用户设备从基站接收分组。 基于给定分组的不完整内容，用户设备可以在分组仍在接收时调用解码。 这种“部分分组解码”依赖于以冗余（代码率小于1）对分组中的底层信息进行编码的事实。 如果链路质量差，则部分分组解码可能不成功，即在尝试恢复基础信息时失败。 为了避免浪费电力，用户设备可以被配置为在对当前分组调用部分分组解码之前应用一个或多个链路质量测试。

    Abstract: Apparatus and methods for implementing “intelligent” receive diversity management in e.g., a mobile device. In one implementation, the mobile device includes an LTE-enabled UE, and the intelligent diversity management includes selectively disabling receive diversity (RxD) in that device upon meeting a plurality of criteria including (i) a capacity criterion, and (ii) a connectivity criterion. In one variant, the capacity criterion includes ensuring that an achievable data rate associated with a single Rx (receive) chain is comparable to that with RxD.

    Abstract: Mechanisms for operating a wireless user equipment device, to determine the state of data scheduling activity. Such activity state (and other information such as measurements of signal interference and/or channel condition) may be used to dynamically control the selection of a high-power high-performance receiver vs. a low-power basic receiver. A first mechanism involves transitioning to a high activity state and starting a timer upon each occurrence of scheduled subframe. A transition to the low activity state occurs whenever the timer expires. A second mechanism involves filtering a sequence of binary-valued indicators corresponding respectively to a sequence of time intervals. Each indicator indicates whether a subframe is scheduled during the corresponding time interval. The filter output is compared to a threshold to determine high/low activity state. The temporal width of the filter impulse response may be increased to support fast initial response without harming the accuracy of activity-state determination in the steady state.

    Abstract translation: 操作无线用户设备设备的机制，确定数据调度活动的状态。 可以使用这种活动状态（以及诸如信号干扰和/或信道状态的其它信息）来动态地控制大功率高性能接收机与低功率基本接收机的选择。 第一种机制包括转换到高活动状态，并且在每次出现调度子帧时启动定时器。 每当定时器到期时，都会转换到低活动状态。 第二机制包括分别对应于一系列时间间隔的二进制值指示符序列。 每个指示符指示在对应的时间间隔内是否安排子帧。 滤波器输出与阈值进行比较，以确定高/低活动状态。 可以增加滤波器脉冲响应的时间宽度以支持快速初始响应，而不会损害稳态下的活动状态确定的准确性。

    Abstract: Methods and apparatus to mitigate interference among multiple wireless subsystems of a wireless communication device are described. A host processor obtains configurations for a plurality of wireless subsystems and evaluates whether potential or actual coexistence interference exists between two or more of the wireless subsystems. The host processor provides configuration information and link quality reporting parameters to and obtains link quality reports from at least two wireless subsystems. When link quality for at least one wireless subsystem fails a set of link quality conditions, the host processor adjusts data requirements for applications that communicate through one or more of the wireless subsystems and/or adjusts radio frequency operating conditions for one or more of the wireless subsystems to mitigate interference among the wireless subsystems.
