Abstract: Extending cellular telecommunication service from a first UE to another device. The first UE may register for cellular telecommunication service with a cellular network using a first cellular service account, using a cellular communication link via a cellular radio. A second device may be discovered and a communication link may be established between the first UE and the second device. The second device may be registered to use cellular telecommunication capability provided by the first UE. Communications between the second device and the cellular network may be conveyed via the communication link between the first UE and the second device and the cellular communication link. Conveying communications between the second device and the cellular network may provide use of the first cellular service account for cellular telecommunication service to the second device.

Abstract: Embodiments for securely determining a separation distance between wireless communication devices is provided. These embodiments include receiving a measurement request and a first random identifier from a first wireless communication device at a second wireless communication device. The embodiments also includes deriving a transient key using the first random identifier, a second random identifier (generated by the second device), and a pre-shared key. The first and second random identifiers, the pre-shared key, and the transient key derived therefrom are shared between the first and second devices, but are not known to any other devices. The embodiments further include encrypting measurement data exchanged between the two devices using the transient key, and using the encrypted measurement data to calculate and verify a separation distance between the devices. The embodiments thus prevent dishonest wireless communication devices from intercepting communications and spoofing a location of one of the two honest devices.

Abstract: After detecting an access-intent operation, an electronic device establishes a connection with a second electronic device using a communication protocol. The electronic devices exchange identifiers, and the second electronic device provides information specifying a preferred channel to use with a second communication protocol. Based at least in part on the preferred channel of the second electronic device and on communication contexts of the electronic devices, the electronic device selects a channel and transmits to the second electronic device information specifying the selected channel. The electronic device remotely accesses credential information based on the exchanged identifiers, and using the credential information, the electronic devices establish a secure connection via the selected channel using the second communication protocol. The electronic device determines a distance to the second electronic device using wireless ranging via the secure connection. When the electronic devices are proximate to each other, the electronic device can be unlocked.

Abstract: This document describes multicast communication between wireless devices. A scheduling frame may be wirelessly transmitted by a wireless device. The scheduling frame may include a multicast address indicating a group of intended receiving devices for a payload frame. The scheduling frame may further include scheduling information indicating an order for the group of intended receiving devices to transmit acknowledgement information for the payload frame. A payload frame may also be wirelessly transmitted by the wireless device. The payload frame may include payload information intended for the group of intended receiving devices. Additionally, acknowledgement frames may be wirelessly received by the wireless device from at least a subset of the group of intended receiving devices. The acknowledgement frames may be received according to the order indicated in the scheduling information.

Abstract: Apparatus and methods for configuring wireless circuitry of a wireless communication device associated with a wireless local area network (WLAN) access point (AP) to use a reduced power consumption mode are disclosed. While associated with a multiple-input multiple-output (MIMO) WLAN AP and operating in a MIMO mode that includes at least two spatial streams for communication with multiple radio frequency (RF) receive chains active, the wireless communication device transmits a message indicating a request to use a spatial multiplexing power save (SMPS) mode that supports only one spatial stream and requires only a single active RF receive chain. The wireless communication device monitors packets received from the WLAN AP after a guard interval following the request and only switches to the SMPS mode when all packets received after the guard interval use only one spatial stream.

Abstract: A method, station and computer readable storage medium used to perform a roaming procedure. The method performed by the station including determining whether a roam is to be performed, the station being associated with a first access point (AP), receiving network related information for at least one second AP, determining a score value for each of the at least one second AP based upon the network related information, the score value being either a quantitative score calculated as a function of a respective received signal strength indicator (RSSI) value and a respective load value or a qualitative score calculated as a function of a preference value and the RSSI value, selecting one of the at least one second AP based upon the score values and roaming from the first AP to the selected one of the at least one second AP.

Abstract: In order to improve the quality of a telephone call communicated over a wireless local area network (WLAN), an electronic device (such as a cellular telephone) may obtain one or more performance metrics based on communication with another electronic device (such as an access point) via a connection in the WLAN. For example, the electronic device may receive the one or more performance metrics from the other electronic device and/or may determine the one or more performance metrics based on the performance of the communication. Then, the electronic device may compare the one or more performance metrics with an interference criterion. If the interference criterion is met, the electronic device may perform a remedial action, such as selectively discontinuing use of the WLAN to communicate the telephone call for a time interval. Otherwise, the electronic device may continue using the WLAN to communicate the telephone call.

Abstract: A low-power roaming mechanism is described. This low-power roaming mechanism is used by a portable electronic device when the portable electronic device enters a stand-by mode (sleep mode). During this stand-by mode, the portable electronic device allows a wireless interface to look for surrounding wireless networks with a configurable quota. This quota is allotted for roaming based on the usage or communication pattern of the portable electronic device. Once the allotted quota is completely used, the portable electronic device is blocked from performing roaming operations to prevent the portable electronic device from draining the battery.
