Abstract: One or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A wireless station may determine a further availability window schedule for a first time period, including specifying availability for particular channels at particular time slots at a first time slot increment. The wireless station may specify availability at a second time slot increment for a subset of the time slots specified at the first time slot increment. The second time slot increment may be less than the first slot time increment. The wireless station may negotiate, with a neighboring wireless station, a peer-to-peer communication schedule for the peer-to-peer communication application based on the further availability window schedule, including specifying a portion of the peer-to-peer schedule using the second time slot increment.

Abstract: An interface circuit in an electronic device may contend for access to a shared communication channel on behalf of the electronic device and a recipient electronic device, where the access has a duration. Then, the electronic device may provide a schedule frame intended for the recipient electronic device that includes information that specifies one or more time slots during the duration that are associated with the recipient electronic device and one or more communication functions of the recipient electronic device in the one or more time slots. Moreover, the electronic device may provide a data frame with data intended for the recipient electronic device. In response, the electronic device may receive a response frame associated with the recipient electronic device, where the response frame is received during at least one of the one or more time slots.

Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.

Abstract: One or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A wireless station may be configured to perform a method to accelerate discovery of a peer device after an out-of-band triggering event. For example, a wireless device may detect an out-of-band triggering event and activate a wireless interface capable of peer-to-peer communications in response. The wireless device may transmit one or more discovery messages (e.g., discovery beacons, active subscribe messages, and/or unsolicited publish messages) over the wireless interface immediately after activation of the wireless interface to aid in discovery of the peer device. The one or more discovery messages may be transmitted as service discovery frames. The wireless device may perform service discovery over the wireless interface with the peer device post discovery.

The first and second wireless device may perform ranging communication according to the granted ranging priority.

Abstract: Methods for performing a ranging procedure according to the non-trigger-based protocol may include negotiating timing parameters associated with the ranging procedure, performing a ranging measurement, and transmitting/receiving, after completion of the ranging measurement, a message announcing initiation of another ranging measurement. The timing parameters may indicate a time window in which an initiating device can initiate a subsequent ranging measurement and the message announcing initiation of the second ranging measurement may be received during the time range specified. Timing parameters may indicate a responding device's required minimum and maximum time between ranging measurements. Additional parameters may indicate an initiating device's required minimum and maximum time between ranging measurements. A power savings mode may be entered after the first ranging measurement and during at least a portion of a time period specified by the parameters.

Abstract: Methods, systems, and apparatus are presented for performing network probing. A user equipment device (UE) may store a record associating traditional service set identifiers (SSIDs) with corresponding Short SSIDs. According to some embodiments, the UE may receive a message including a Short SSID, and determine whether a corresponding full SSID is known to the UE. Based on the determination, a probe request may be generated, addressed to either the Short SSID or the full SSID. After transmitting the probe request, the UE may receive a probe response, which may include a full SSID corresponding to the Short SSID. The UE may store a record associating the full SSID with the Short SSID, if applicable. According to some embodiments, a UE may receive a plurality of messages including respective SSIDs, and may generate a single probe request addressed to the SSIDs. The UE may receive a plurality of probe responses.

Abstract: A recipient electronic device that receives a wake-up frame is described. This recipient electronic device may include an interface circuit that communicates with an electronic device, where the interface circuit includes a main radio and a wake-up radio (WUR) that at least selectively transitions the main radio from a lower-power mode to a higher-power mode. During operation, the WUR receives the wake-up frame intended for the recipient electronic device, where the wake-up frame comprises a payload field with data. For example, the wake-up frame may specify: a total size of the wake-up frame, and/or a size of the payload field. In response to the wake-up frame, the WUR selectively transitions the main radio from the lower-power mode to the higher-power mode. Moreover, the main radio provides an acknowledgment associated with the recipient electronic device that indicates that the recipient electronic device received the wake-up frame.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up-radio (WUR) discovery frame for a recipient electronic device, where the WUR discovery frame includes an operating class of a wireless local area network (WLAN) associated with the electronic device.

The amount of compression may be based at least in part on a communication environment of the electronic device, such as a number of electronic devices, or a number of neighboring WLANs. Thus, the WUR discovery frame may have a variable size or length.

Abstract: Passive and active scanning for extended range wireless networking. The choice between legacy and extended range signaling can depend on one or more factors. For passive scanning, an electronic device may transmit a combination of legacy beacons and extended range beacons for network discovery by receiving electronic devices. For active scanning, an electronic device may transmit extended range probe requests in addition to legacy probe requests to discover all of the access points within its transmission range. Responses to probe requests can use extended range, legacy, single user, and/or multi user protocols.

Abstract: A station (STA) of a wireless local area network (WLAN) transitions implicitly between power management (PM) modes or PM states, without providing an explicit indication of the PM mode/state change to an access point (AP) of the WLAN. Transitions include changes between an active mode and a power save (PS) mode, or between an awake state and a doze state of the PS mode. Transitions occur immediately after receipt of a beacon indicating pending data for the STA, after an offset time indicated in the beacon, or at a specific wake time negotiated with the AP. After data reception is complete, the STA transitions implicitly to the PS mode or a doze state of the PS mode, after a power save inactivity timeout period or after receiving an indication that data transmission is complete.

Abstract: Disclosed herein are system, method, and computer program product embodiments for identity obscuration of a station (STA) connected to a wireless network to prevent the tracking of the STA. Embodiments include a STA configured to establish a security association with an access point (AP) based on an original long term identity for the station and an identity of the AP. The STA can transmit a new long term identity for the STA to the AP based on the security association. The STA can then transmit a request frame to change the original short term identity assigned to the STA to the AP. The STA can receive a response frame from the AP. The response frame can include a new short term identity assigned to the station by the AP. The STA can then map its new long term identity to its new short term identity assigned by the AP.
