  • Changing topology of wireless peer-to-peer group
    Patent number: 10051441
    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.

  • COMMUNICATION WITH I-Q DECOUPLED OFDM MODULATION
    Publication number: 20180123856
    Abstract: In some examples, an apparatus includes a transmitter configured to apply input data as a frequency-domain data sequence to modulate a set of subcarriers, and separate the frequency-domain data sequence into a first subsequence of elements and a second subsequence of elements. A first conjugate symmetric subsequence that is based on inserting a zero value into the first subsequence is formed, and a second conjugate symmetric subsequence that is based on inserting a zero value into the second subsequence is formed, where the zero values are inserted at different positions in the first and second subsequences. A time-domain sequence comprising a first component that is a function of the first conjugate symmetric subsequence, and a second component that is a function of the second conjugate symmetric subsequence is generated.

  • GROUP-ADDRESSED TRANSMISSION OF INFORMATION RELATING TO AN ACCESS NETWORK
    Publication number: 20180115938
    Abstract: In some examples, an access point determines, based on at least one criterion that includes a non-time based criterion, whether to activate group-addressed transmission of information relating to an access network. In response to determining, based on the at least one criterion, to activate group-addressed transmission of information relating to the access network, the access point transmits information relating to the access network in a message targeted to a group address.

  • Methods and Apparatus to Discover Authentication Information in a Wireless Networking Environment
    Publication number: 20180070236
    Abstract: Examples to discover network authentication information in a wireless network involve transmitting during network discovery and prior to authentication, a Generic Advertisement Service (GAS) request to a network access point.

  • Extended Service Set Transitions in Wireless Networks
    Publication number: 20180070271
    Abstract: A mobile device may transition between Extended Service Set (“ESS”) networks seamlessly, such that a consumer never loses the network connection despite the transition. The communication for enabling a transition may be prior to association with that network. The seamless transition may be enabled through the creation and utilization of a central key holder authority that advertises its identity to mobile devices in a pre-associated state. The mobile device can use the key discovery communication along with a key generation method to authenticate and/or associate with a network and transition from one ESS to another. There may be a common root key across ESSs. At each new access point (“AP”) that the mobile device encounters, ESS and key holder identities may be discovered through discovery communications.

  • Discovering Network Information Available via Wireless Networks
    Publication number: 20180042058
    Abstract: Network information may be discoverable without requiring a connection to that network. For example, Access Network Query Protocol (“ANQP”) may allow a device to discover information about a network prior to the device associating with that network. In other words, ANQP allows a network terminal to request additional network information prior to establishing network capability. The additional network information that may be discoverable includes network latency, cellular capabilities, hotspot capabilities, mobility capabilities, neighbor reports, station identification, and multiple hotspot session identification.
