Abstract: Methods and apparatus to support scheduled access control for an electronic lock are described herein. An initiating central wireless device obtains an ephemeral identity resolving key (IRK) to use in resolving an ephemeral resolvable private address (RPA) of a peripheral wireless device. The initiating central wireless device can subsequently connect securely to the peripheral wireless device in order to unlock an electronic lock controlled by the peripheral wireless device to gain access during a scheduled time period. The ephemeral IRK and ephemeral RPA can be used for a limited period of time and/or for a predetermined number of usages during the scheduled time period.

Abstract: Systems, methods, and mechanisms for an out-of-band (OOB) ultra-wide band (UWB) channel arbitration and/or channel coordination scheme. A device may scan an arbitration channel for a first time period, and based on the scanning, determine that the arbitration channel is not in use. The device may perform, on the arbitration channel, a first channel access procedure and perform, on the UWB channel, UWB communications during a UWB channel transmission opportunity.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QOS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing uplink access in a wireless local area network. A station (STA) may inform an access point (AP) of uplink quality of service (QoS) parameters for a traffic flow from the STA. The AP may control uplink resources to satisfy the QoS parameters. For example, the AP may select from among different access modes (including a single user (SU) access mode, an uplink multi-user (UL-MU) scheduled access mode, a multi-user enhanced distributed controlled access (MU EDCA) access mode, or a low latency (LL) access mode). The AP may cause the STA to use a SU access mode or the LL access mode if the UL-MU scheduled access mode and the MU EDCA access mode are not sufficient to satisfy the uplink QoS parameters for the traffic flow.

Abstract: This disclosure relates to methods for handling uplink frames in access point assisted roaming in a wireless local area network. A wireless device may establish a wireless association with a first access point. The wireless device may perform signaling to transition from the first access point to a second access point. The signaling may include an uplink reorder buffer handling request.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: during transmission of two or more physical layer protocol data units (PPDUs) during a transmission opportunity (TXOP), determining that an urgent PPDU should be transmitted during the TXOP; and enabling, before transmission of all of the two or more PPDUs during the TXOP, transmission of the urgent PPDU.

Abstract: Some embodiments include an apparatus, method, and computer program product for dynamic window access point (AP) power save enhancements. Some embodiments include transmitting an availability window (AW) of an AP to stations (STAs) and dynamically modifying the AW. In some embodiments, a mobile device may perform soft AP functions and associate with the stations. The modifications can include truncating or extending the AW. Some embodiments include: a broadcast availability frame that informs STAs of the modified AW; an Availability Clear To Send (A-CTS) frame that allows the AP to inform associated STAs of the modified AW; and/or an uplink (UL) multi-user (MU)-Request to Send (RTS) Enabled feature, that allows an AP to be available while operating in a low power receive (LPR) state (e.g., low power mode) and transition to a full power state to receive data using a bandwidth greater than 20 MHz.

Abstract: Systems, methods, and mechanisms for a sub-transmit opportunity (sub-TxOP) and/or sub-TxOPs within a transmit opportunity (e.g., TxOP) to reduce channel access delays in wireless systems, e.g., such as in current and future IEEE 802.11 systems. A wireless device (e.g., an access point or wireless station) may transmit, at a start of a TxOP to one or more wireless devices, signaling indicating that the TxOP includes one or more sub-TxOPs. The wireless device may contend, during a first contention period (CP) preceding a first sub-TxOP of the one or more sub-TxOPs, for access to a medium. The wireless device may transmit, upon determining that the wireless device can transmit in the first sub-TxOP, data to at least one wireless device of the one or more wireless devices.

Abstract: This disclosure relates to methods for managing uplink transmit opportunity bursting for wireless local area networking. A wireless device may initiate a transmit opportunity to perform an uplink transmission to an access point. The wireless device may receive an acknowledgement from the access point. The acknowledgement may include an indication that the wireless device can initiate a second transmit opportunity without wireless medium contention. The wireless device may initiate the second transmit opportunity without wireless medium contention based at least in part on the indication received from the access point.

Abstract: Some embodiments include an apparatus, method, and computer program product for infrastructure and peer-to-peer (P2P) medium access sharing. Some embodiments enable an access point (AP) to assist associated stations (STAs) in accessing a channel. In some embodiments, an AP can receive a request for coordinated transmission for peer-to-peer (P2P) communications, determine a bandwidth available for use during a transmit opportunity (TXOP), and allocate, from the bandwidth, a first subset of one or more channels for infrastructure communications and a second subset of one or more channels for the P2P communications responsive to the request. The AP can transmit to a STA, a first signal corresponding to the second subset of one or more channels for the P2P communications, indicating that the second subset of one or more channels can be used for P2P communications during the TXOP.

Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may transmit, to a second AP and during a first portion of a transmission opportunity (TxOP), a request to participate in a multi-user (MU) transmission. The AP may receive, from the second AP and during the first portion of the TxOP, an indication of intent to participate in the MU transmission during the second portion of the TxOP, the indication of intent including a resource request of the second AP for participation in the MU transmission. The AP may transmit, during an initial period of the second portion of the TxOP, a trigger signal to the second AP indicating a set of one or more resources for the second AP during the MU transmission. The AP may participate, in conjunction with the second AP and during the second portion of the TxOP, in the MU transmission.

Abstract: This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period.

Abstract: Various aspects of the techniques, methods and devices described in this disclosure relate generally to achieving coexistence between WLAN and P2P networks, and specifically, to coordinated D2D communications. Some aspects particularly involve extending the capabilities of TWT elements transmitted by APs to support periodic reserved access windows during which D2D-enabled wireless devices are permitted to transmit direct wireless communications. Some other aspects relate to sharing time and frequency resources via CAP TDMA or CAP OFDMA techniques, and specifically, to allocating at least some of the time and frequency resources specifically for D2D communications.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing request to send (RTS) and clear to transmit (CTS) frames and transmission rules for the RTS and CTS frame. For example, some aspects relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive, using the transceiver, a request to send (RTS) frame from the second electronic device and determine, using the received RTS frame, a format for a clear to send (CTS) frame to use in response to the RTS frame. The one or more processors further transmit, using the transceiver, the CTS frame based on the determined format on at least one sub-channel on which the RTS frame was received and that the at least one sub-channel is idle.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including detecting a reception opportunity of a physical layer protocol data unit (PPDU) scheduled to be transmitted by a transmitter, where the PPDU includes a preamble and one or more media access control (MAC) PDUs (MPDUs); decoding the preamble of the PPDU; detecting that reception of the one or more MPDUs has failed; and in response to the detecting, preparing a Negative Acknowledgment (NACK) message for transmission to the transmitter.

Abstract: Methods, systems and apparatuses for managing roaming by access points (AP), a controller, and a wireless device are described.

The wireless device, APs, and controller can adjust delivery of uplink and/or downlink data in association with the roam.

Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.

Abstract: Some embodiments include an apparatus, method, and computer program product for access point (AP) power save enhancements. AP power save enhancements reduce power consumption for APs including multi-link device (MLD) APs, mobile APs and mobile AP stations. Some embodiments include an uplink (UL) multi-user (MU)-Request to Send (RTS) power save feature, that allows an AP to be available while operating in a low power receive (LPR) state (e.g., low power mode) and transition to a full power mode to receive data using a bandwidth greater than 20 MHz. Some embodiments include a Target Wake Time (TWT) UL MU-RTS AP power enhancement feature that allows an AP to operate in the LPR during a TWT service period (SP). Some embodiments allow mobile devices (e.g., a smart phone) to operate in as an AP (e.g., a mobile AP, a mobile AP station) and reduce power consumption.

Abstract: Some embodiments include an apparatus, method, and computer program product for access point (AP)-assisted AP transition. Using AP-assisted AP transitions, when the STA is associated with a first access point (AP) and is transitioning to a second AP, a station (STA) can transmit to the second AP a control signal including a first indication for sequence number (SN) maintenance. The STA can receive from the second AP responsive to the first indication for SN maintenance, a first downlink (DL) transmission including a next SN. The next SN can be a continuation of an SN sequence utilized by the first AP for one or more previous DL transmissions.
