  • Patent number: 9912588
    Abstract: An IEEE 802.11 media access control (MAC) frame (or contents thereof) at a transmitter apparatus includes information from which a logical channel carrying traffic can be identified, so that a receiver apparatus, when unpacking the IEEE 802.11 MAC frame (or contents thereof), is able to route the traffic to the appropriate radio link control (RLC) entity associated with the logical channel. An evolved Node B (eNB) that is also an access point (AP) distinguishes conventional uplink wireless local area network (WLAN) traffic from traffic that is to be routed to an RLC layer.

  • Publication number: 20170332286
    Abstract: In some examples, a wireless device receives, from an access point (AP), information indicating that the wireless device is to cease transmission in a first channel. In response to the information, the wireless device communicates with the AP in a second channel that is a subset of the first channel, during a time interval in which the wireless device is to cease transmission in the first channel.

  • Publication number: 20170257819
    Abstract: In some examples, a headless device that is without an available user interface and that is to be provisioned for access to a network receives information relating to provisioning of the headless device from a network node. The headless device sends, to a mediator device with a user interface, at least a portion of the received information. The headless device receives, from the mediator device, information to proceed with the provisioning of the headless device.

  • Patent number: 9668094
    Abstract: A method of selecting a cellular network entails detecting a Wi-Fi signal, obtaining a country code from the Wi-Fi signal, prioritizing cellular network frequency bands based on the country code to define a band priority, and selecting a cellular network based on the band priority. The country code may be an IEEE 802.11d Country Code Information Element.

  • Patent number: 9654965
    Abstract: A wireless device may be subject to regulations based on the location (e.g. country). Accordingly, the wireless device may need to identify regulations for its current location. A lookup table or database that includes regulations for different locations may be used for identifying the regulations for the current location of the wireless device. The lookup table may be stored locally on the wireless device or retrieved over a network. The identified regulations may be used to modify certain operating parameters of the wireless device to comply with the local regulations and determine whether or not to associate with an incorrectly configured Access Point.

  • Publication number: 20170105102
    Abstract: A device in a peer-to-peer (P2P) group has the role of group owner. A different device in the P2P group may take on the role of group owner without ending the P2P group and create a new P2P group. Multiple P2P groups may be merged into a single P2P group. A single P2P group may be split into multiple independent P2P groups, each with its own group owner. A group owner of a P2P group may notify the client devices in the P2P group that it is about to leave the P2P group. A client device in a P2P group may be appointed in a new role of backup group owner, to take on the role of group owner in the event of a departure of the group owner, thereby providing continuity. Techniques for maintaining upper layer continuity through changes in topology of P2P groups are disclosed.

  • Publication number: 20170078408
    Abstract: A network node of a wireless local area network (WLAN) filters, based on at least one policy, information about services available via the network node. The network node sends, to a wireless device as part of a pre-association discovery operation of the wireless device, the filtered information about the services.

  • Publication number: 20170013539
    Abstract: A device decides to not transmit over a first wireless link between a wireless device and a first access point (AP), in response to determining that the wireless device is communicating or is about to communicate over a second wireless link with a second AP, wherein the wireless device is concurrently associated with the first and second APs.

  • Publication number: 20160323811
    Abstract: A deterministic random number generator at a first wireless communication node computes a pseudorandom number. The deterministic random number generator employs a same random number generation algorithm as a random number generator of a second wireless communication node. The first wireless communication node determines a timing of a randomized beacon transmission using the computed pseudorandom number.

  • Publication number: 20160261430
    Abstract: A bridge communicates a link layer frame between a device and a cellular access network node, the link layer frame comprising a portion including a header and data of an upper layer protocol layer instance in the device or the cellular access network node. The header includes identification information to identify which of a plurality of upper layer protocol layer instances the data is associated with.

  • Publication number: 20160173586
    Abstract: A device may communicate with a peer-to-peer (P2P) network prior to associating with that network. The communications prior to association may include information about whether the P2P network is persistent or non-persistent. The information may include a persistent group intent field that identifies whether a device would prefer to join a persistent P2P network and allows a P2P network to advertise whether it is persistent.

  • Publication number: 20160143085
    Abstract: In some implementations, a power saving method includes receiving, from a base station, at a user equipment (UE), a Discontinuous Reception (DRX) configuration. The UE determines a WLAN listen interval that includes at least one Traffic Indication Map (TIM) period and at least one TIM transmission period. The UE selects, based on the DRX configuration, a TIM message to monitor within an associated TIM transmission period from the at least one TIM transmission period in the listen interval. The UE determines a WLAN wakeup time that overlaps the associated TIM transmission period. During the associated TIM transmission periods, the UE receives, from an Access Point (AP), the selected TIM message.
