Abstract: In order to reduce power consumption of an electronic device during communication with another electronic device in a wireless local area network (WLAN), the electronic device analyzes fields in a given packet prior to a payload of the given packet to look for information that specifies a destination of the given packet. For example, the information may include: a full associated identification (AID) of the destination, a partial media-access-control (MAC) address of the destination; and/or a compressed (MAC) address of the destination. The information may be included in the preamble of the given packet. In particular, the information may replace length information in a high-throughput signal field in the given packet. Moreover, if the destination is other than the electronic device, the electronic device dumps the given packet and changes a power state of the electronic device, thereby reducing the power consumption.

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: 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: A method of modulating transmission power to facilitate in-device coexistence between wireless communication technologies is provided. The method can include determining a scheduled time period during which data is received by a device via a first wireless communication technology. The method can further include reducing a transmission power of a transmission from the device via a second wireless communication technology to a threshold level prior to the scheduled time period and controlling the transmission power so that the transmission power does not exceed the threshold level during the scheduled time period. The method can additionally include, subsequent to the time period, increasing the transmission power to a level exceeding the threshold level.

Abstract: A station (STA) can receive messages (e.g., beacon frames) at a regular interval, and perform measurements on the received messages. The STA maintains a running average of recent measurement values, and updates the running average after each new measurement interval. At some measurement opportunities, the expected messages cannot be received by the STA, and so the STA cannot perform a measurement; when this occurs, the STA can choose substitute values to use for the missed measurements when next calculating the running average. As one example, the STA can substitute the value for a previously-performed measurement for the missed measurements. As another example, the STA can substitute a predetermined low value for the missed measurements. Based on the value of the running average at a given point in time, the STA can take actions such as initiating a roaming scan or switching to a different wireless interface.

Abstract translation: 站（STA）可以以规则的间隔接收消息（例如，信标帧），并对所接收的消息执行测量。 STA保持最近测量值的运行平均值，并在每个新的测量间隔之后更新运行平均值。 在某些测量机会中，STA不能接收预期的消息，因此STA不能执行测量; 当发生这种情况时，STA可以选择替代值，用于下次计算运行平均值时的错过测量。 作为一个示例，STA可以将该值替换为先前执行的测量用于错过测量。 作为另一示例，STA可以将预定的低值替换为错过的测量。 基于给定时间点的运行平均值，STA可以采取行动，例如启动漫游扫描或切换到不同的无线接口。

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.
