    Abstract: In order to reduce power consumption of an electronic device during communication with another electronic device in a wireless local area network (WEAN), 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 translation: 为了在与无线局域网（WEAN）中的另一电子设备通信期间减少电子设备的功耗，电子设备在给定分组的有效载荷之前分析给定分组中的字段，以查找指定 给定包的目的地。 例如，信息可以包括：目的地的完全相关联的标识（AID），目的地的部分媒体访问控制（MAC）地址; 和/或目的地的压缩（MAC）地址。 信息可以被包括在给定分组的前导码中。 具体地，该信息可以替代给定分组中的高吞吐量信号字段中的长度信息。 此外，如果目的地不是电子设备，则电子设备转储给定分组并改变电子设备的功率状态，从而降低功耗。

    Abstract: A method for determining whether an acknowledgement received by a user equipment from an external device is a forced acknowledgement. The method including transmitting a set of data stored in an uplink buffer to an external device, receiving an acknowledgement from the external device, determining if the acknowledgement received from the external device was a forced acknowledgement and flushing out an uplink buffer if determined that the acknowledgement was not a forced acknowledgement. The determining the acknowledgement is a forced acknowledgment being based on whether an uplink retransmission collides with one or more scheduled transmission times, a Physical Hybrid-ARQ Indicator Channel (PHICH) falls between gap measurements and an uplink retransmission collides with one of the gap measurements or a TTI bundling retransmission collides with a gap measurement. If the acknowledgement is not a forced acknowledgment, a set of data stored in the uplink buffer is retransmitted to the external device.

    Abstract: A single chip mobile wireless device capable of receiving and transmitting over one wireless network at a time maintains registration on two wireless communication networks that each use different communication protocols in parallel. Periodically, the mobile wireless device tunes one or more receivers from a first wireless network to a second wireless network in order to listen for paging messages addressed to the mobile wireless device from the second wireless network. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device.

    Abstract: A wireless electronic device having first and second baseband processors is provided. In one suitable arrangement, radio-frequency power splitters and adjustable low noise amplifiers may be form in the receive paths. The use of power splitters allow signals associated with the first and second baseband processors to be received in parallel. In another suitable arrangement, radio-frequency switches are used in place of the power splitters. The states of the switches may be controlled using at least one of the first and second baseband processors. The use of switches instead of power splitters requires that wake periods associated with the first baseband processor and wake periods associated with the second baseband processor are non-overlapping. To ensure minimal wake period collision, a wake period associated with the second baseband processor may be positioned at a midpoint between two successive wake periods associated with the first baseband processor.

    Abstract: Various embodiments are disclosed of a method and apparatus for fast communication recovery in wireless mobile devices arranged to perform dual network radio resource management. In one embodiment, a wireless mobile device includes a transceiver configured to communicate with each of first and second networks. After establishing and maintaining a link with the first network, the wireless mobile device may tune a transceiver to the second network to monitor for traffic, subsequently tuning back to the first network. After turning the transceiver back to the first network, the wireless mobile device may perform one or more attempts to restore the link to the first network. The number of attempts to restore the link is dependent upon an amount of time the transceiver is tuned to the second network.

    Abstract: Apparatus and methods for a hybrid automatic repeat request (H-ARQ) mechanism for wireless communication devices of a wireless local area network (WLAN) are disclosed. Methods and apparatus to determine whether a packet is an original, first transmission or a retransmission of a previously transmitted packet without decoding the payload of the packet are disclosed. Medium access control (MAC) addresses of a transmitter, such as an access point (AP), and a receiver, such as a station (STA), of a WLAN are encoded separately with a retransmission bit to indicate whether the packet is retransmitted. For an aggregated MAC protocol data unit (A-MPDU), a sequence number is included to determine which MAC protocol data units (MPDUs) of the A-MPDU are retransmitted. When retransmission is indicated, the receiver of the STA performs a hybrid automatic repeat request (H-ARQ) process to combine the retransmitted packet with previously received packets.

    Abstract: In order to facilitate communication between an electronic device and another electronic device, the electronic device determines communication-quality metrics for a first connection in a wireless network based on received information from the other electronic device. Then, the electronic device calculates an overall communication-quality indicator for the first connection based on at least some of the communication-quality metrics. Moreover, the electronic device dynamically adapts the communication with the other electronic device based on the overall communication-quality indicator. For example, the electronic device may establish a second connection in a cellular-telephone network and may use the second connection to communicate with the other electronic device. Alternatively, the electronic device may provide the overall communication-quality indicator to the other electronic device and may at least partially transition the communication from the second connection in the cellular-telephone network to the first connection in the wireless network.
