摘要:
A wireless communication device comprises a transceiver configured to communicate information with one or more neighbor devices in accordance with a sync mode of a WiFi communication protocol, and a controller. The controller is configured to monitor for reception of at least one of a response frame or a beacon frame sent by any neighbor device, determine whether to schedule transmission of a service frame, and change operation to a background scan mode when the at least one of the response frame or the beacon frame sent by any neighbor device is undetected for a specified time duration and the transmission of a service frame is unscheduled.

Embodiments of a user station (STA) and methods for device-to-device discovery and advertisement through broadcast beacon signals are generally described herein. In some embodiments, group information, including a list of STAs in an advertising group, is transmitted in a beacon. A STA may transmit a request to join the advertising group. The request may be transmitted to an upchain STA, the upchain STA being determined based on inspection of the list of STAs of the advertising group. After receiving a response to the request, the STA may periodically broadcast the beacon and the STA may transmit acknowledgements to the upchain STA upon receiving beacons from the upchain STA.

Logic to manage synch frame transmissions in a synch network via helper stations (STAs) synched to the network. Logic may coordinate actions of helper STAs via a transmission window (TW) provided by a master clock STA. Logic may distribute synch frame transmissions within a TW via synch logic in the helper STAs. Logic in helper STAs of a synch network may determine discovery periods in which to transmit synch frames between synch frame transmissions by the master clock STA. Logic in helper STAs to determine a discovery period in which to transmit synch frames to share workload with the master clock STA and to extend the coverage area of the synch network. Logic of the master clock STA may establish a fixed TW based upon the number of helper STAs and a time constraint for discovering the synch network. Or logic of the master clock STA may establish a dynamic TW in which the master clock STA can adjust the TW based upon a number of synch frame transmissions during a TW.

Examples are disclosed for multi-level service discovery. In some examples, a first level of information indicating a service type for a service provided by a first wireless device may be transmitted by the first wireless device to another wireless device. The first level may enable the other wireless device to determine whether the indicated service type at least partially matches a service interest. A second level may then be transmitted by the first wireless device that includes a service identification to enable the other wireless device to determine whether the service substantially matches a service interest for the other wireless device. A third level may then be transmitted from the first wireless device that includes service content information. The third level may be transmitted responsive to the other wireless device requesting the service content information. Other examples are described and claimed.

A network communication device comprises physical layer (PHY) circuitry configured to transmit and receive radio frequency electrical signals to communicate directly with one or more separate network devices; and medium access control layer (MAC) circuitry. The MAC circuitry is configured to: initiate transmission of a packetized message that includes a neighbor awareness networking (NAN) public action frame; receive a data connection request message from a second network device that includes one or more quality of service (QoS) requirements; initiate transmission of a data connection response message that includes data exchange time window information and channel information; and communicate data device-to-device with the second network device according to the data exchange time window information and channel information.

Logic to “loosely” manage synch frame transmissions in a synch network via the devices synced to the network that implement the logic. Logic may distributedly adjust the frequency of attempting synch frame transmissions without estimating the size of the neighborhood. Logic in devices of a synch network to let each device maintain a Transmission Window (TW). Logic to determine the frequency of attempting synch frame transmissions based upon the TW. Logic to increase TW if the device detects a synch frame transmission. Logic to decrease TW if the device successfully transmits a synch frame. Logic to balance power consumption and discovery timing by adjusting the decrease in TW responsive to a synch transmission in relation to the increase in TW responsive to detection of a synch transmitted by another device.

Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.

Various embodiments are directed to a wireless access point capable of reserving a wireless communication channel by sending a quiet message to multiple legacy devices. The quiet message may include data identifying periodic quiet durations during which the legacy devices cannot access the wireless communication channel. The wireless access point may send a polling schedule to the multiple low power wireless devices. The polling schedule may include data identifying the periodic quiet durations. The wireless access point may then poll the multiple low power wireless devices during the periodic quiet durations. The low power wireless devices can exchange data with the wireless access point during the quiet durations. The quiet message sent to the legacy devices guarantees that the legacy devices will not use the specified channel during the quiet durations. Thus, communications with the low power wireless devices may occur without interference from the legacy devices.

Devices and methods of providing a NAN schedule update are generally described. NAN devices communicate data on a schedule of repeating time blocks in which transmission in different time blocks are on different channels. A public action frame indicates in a subfield that the frame is a schedule update frame. The schedule update frame provides attributes to have general schedule update for availability time, existing unicast service or existing multicast service. The schedule update frame also contains a schedule update control field that indicates in a subfield that the current time block is cancelled or extended or provides a general schedule update. The schedule update control field also indicates a reason for the schedule update.
