Techniques to manage connection capabilities information for a wireless communications system are described. In various embodiments, for example an apparatus may comprise a processor circuit, a communications component for execution by the processor circuit to perform neighbor awareness networking (NAN) service discovery and to receive a NAN information element (IE) during the NAN service discovery, the NAN IE comprising a connection capability bitmap field describing one or more connection capabilities of a remote device, and a determination component for execution by the processor circuit to determine whether to initiate a connection with the remote device based on the connection capability bitmap field. Other embodiments are described and claimed.

Certain embodiments of the invention may include systems, methods, and apparatus for a short beacon in low rate Wi-Fi communications. According to an example embodiment of the invention, a method is provided for generating a short beacon. The method can include generating a short beacon frame for transmission at a selectable beacon interval. The short beacon frame includes: a beacon timestamp field, a service set identifier (SSID) field, and one or more capability fields; and generating a traffic indicator map (TIM) frame for transmission at a selectable TIM interval. The TIM frame includes a TIM timestamp field, a check beacon field, and a TIM; and converting the short beacon frame and the TIM frame for wireless transmission over a hardware transmission medium.

In a method and system, a first wireless device may be periodically cycled between an available state and a power saving state. While in the available state, the first wireless device may receive a probe request sent from a second wireless device operating in a discovery state. The first wireless device may transmit a probe response to the second wireless device. Other embodiments are described and claimed.

Some demonstrative embodiments include apparatuses, systems and/or methods of setting up an Application Service Platform (ASP) Peer-to-Peer (P2P) persistent group. For example, an apparatus may include a first ASP to communicate with a second ASP to setup one or more ASP-P2P groups over a wireless communication link, the first ASP is to form each ASP-P2P group only as an ASP-P2P persistent group extendable over a plurality of distinct sessions, the first ASP is to store credentials of the ASP-P2P persistent group for use during the sessions.

Logic may enable a number of Wireless Fidelity (Wi-Fi) enabled devices to synch in a cluster of devices to allow devices to discover services offered by other devices in the cluster such as, e.g., sharing, showing, printing, synching content, emailing, posting, tweeting, facebooking, and any other discoverable services. Logic may awake at different times to scan for timestamps from stations such as access points. Logic may implement passive scans in which the devices wait to receive beacon frames from one or more access points. Logic may implement active scans in which the devices transmit probe request frames to request a probe response frame from one or more access points in proximity to the devices. Logic may determine a synchronization time based upon a timestamp and a time synchronization bit sequence. And logic may determine a discovery period based upon the synchronization time and the time synchronization bit sequence.

In a wireless network, information regarding the power capabilities of a wireless device may be communicated to a wireless AP. The device itself may transmit such information, which may include a Max Idle Time period. The device may communicate the information within an association or re-association frame, for example as a parameter in a BSS Low Power Capability element. The AP may receive the information and set a keep-alive time period for the device based on the information. The AP may set the keep-alive time period to be equal to or greater than the Max Idle period. The AP may further communicate the keep-alive time period to the device, for example in an association or re-association response frame as a BSS Max Idle period element. In this way, the AP may apply different sets of parameters, such as different keep-alive time periods, to different classes of stations.

Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In some embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key.

This disclosure describes systems, methods, and devices related to enhanced power save. A device may determine on-off periods of an access point (AP). The device may generate a frame comprising a target wake time (TWT) element comprising information representing the on-off periods of the AP. The device may cause to send the frame to one or more STAs.
