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: 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, 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: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

Abstract: Techniques are disclosed for obfuscation in a privacy beacon. An example method includes the first device receiving, from a second communication device, a beacon frame comprising a medium access control (MAC) header and an encrypted beacon frame field, the MAC header comprising an obfuscated timing synchronization field (TSF). The first device can select a key for de-obfuscating the TSF based at least in part on information associated with the beacon frame. The first device can de-obfuscate the TSF based at least in part on the key. The first device can decrypt the encrypted beacon frame field of the beacon frame based at least in part on information associated with the de-obfuscated TSF.

Abstract: Embodiments described herein relate to a system and method for providing flexible receiver configuration in wireless communication systems, such as 802.11 WLAN systems. In one embodiment, a wireless device may transmit a first data frame including first configuration information specifying a first configuration of the receiver to notify a remote device that the wireless device intends to configure its receiver according to the first configuration. After receiving an acknowledgement frame confirming the first configuration information, the wireless device may configure the receiver according to the first configuration. In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.

Abstract: A wireless device may use 2.5 MHz narrow band channel spacing. In some embodiments, clear channel assessment based listen before talk may be used to determine if a channel is idle or busy. In some embodiments, randomized channel access may be achieved using a pseudo random number generator on an allowed list of channels. In some embodiments, an avoid loitering mechanism may be employed to reduce interference with transmitters using the same frequency bands.

Abstract: Systems, methods, and mechanisms for WLAN enhancements to facilitate co-existence with other radio access technologies, such as Bluetooth, 5G NR, and/or UWB. For example, WLAN transmissions may be shortened, e.g., to better fit within available transmission times. A wireless device may shorten WLAN transmissions of a peer device by specifying a frame size limitation for WLAN communications. The frame size limitation may be indicated via a data frame, a management frame, a beacon frame, an association request frame, and/or an association response frame.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing a target wake time (TWT) scheme that includes traffic differentiation and service period extension. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive an indication of traffic associated with an application. The one or more processors determine information associated with the traffic and configure the TWT scheme associated with the traffic based at least in part on the determined information. The one or more processors further communicate initial information associated with the TWT scheme to an access point of a wireless network. The initial information associated with the TWT scheme can include at least one of traffic direction information, traffic pattern information, a traffic identifier (TID), or an access category, indication (ACID).

Abstract: Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications via a scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.
