Abstract: A method of communication includes selecting a logical channel of a plurality of logical channels at a first electronic device of a neighbor aware network (NAN). The logical channel indicates a particular communication channel of a plurality of communication channels and indicates a set of transmission windows of a plurality of transmission windows. The method also includes generating a message indicating that the first electronic device is available to communicate with other electronic devices of the NAN and identifying the logical channel. The method further includes transmitting the message to a second electronic device of the NAN.

Abstract: Methods, systems, and devices are described for direct device-to-device (D2D) communications in a subframe on a channel in an unlicensed radio frequency spectrum band. A user equipment (UE) may perform a listen-before-talk (LBT) procedure on the channel in the unlicensed radio frequency spectrum band. The UE may identify a time period between a completion of the LBT procedure and a boundary of a second subframe. The UE may transmit a Wi-Fi preamble and a variable length message on the channel during the identified timer period. The variable length message may include a duration that is time aligned with the boundary of the second subframe.

Abstract: In some examples, a method includes receiving, at a first device, availability information from a second device during a connection set-up phase of communication of a neighbor aware network (NAN) or during a NAN discovery window. The connection set-up phase includes an exchange of device capability information. The method also includes, based on the availability information indicating that the second device is available during a transmission window of a data link group of the NAN to receive data from the first device, sending data from the first device to the second device during the transmission window without performing a message exchange to determine an availability of the second device.

Abstract: Methods and apparatus for independent basic service set based data paths for neighbor aware networks are described herein. In some aspects, an apparatus for wireless communication in an independent basic service set is provide. The apparatus comprises a receiver configured to receive a service discovery frame from a device in a neighbor aware network. The apparatus comprises a processor configured to determine a timing for an announcement traffic indication message window, wherein the timing is defined as an offset from a beginning of a discovery window for the neighbor aware network. The apparatus comprises a transmitter configured to transmit an announcement traffic indication message during the announcement traffic indication message window. The service discovery frame comprises an independent basic service set availability attribute defining a duration of the announcement traffic indication message window.

Abstract: Systems, methods, and apparatuses for efficient infrastructure service discovery with security are disclosed. In one aspect, systems and methods for advertising services available via an access point without requiring a device to connect for discovery are described. This may allow devices to determine, prior to establishing a connection with an access point, whether a desired service is offered. Further description of publication rules is provided. Service providers can use the publication rules to identify service information which may be discovered by devices based on device authentication status or other factors to allow controlled, secure discovery of the service information.
