    Abstract: An electronic device (such as an access point) that provides a frame is described. This electronic device includes: an antenna node communicatively coupled to an antenna; and an interface circuit, communicatively coupled to the antenna node, that communicates with a second electronic device. During operation, the interface circuit may provide, addressed to the second electronic device, the frame that includes an indication that the electronic device uses a frame-based equipment (FBE) channel access technique and attributes of the FBE channel access technique. The attributes may include: a duration of the FBE channel access technique, and a fixed frame period (FFP) for communication during the FBE channel access technique. Moreover, the frame may be compatible with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

    Abstract: Payload transmission of multiple stations on a single resource unit may be performed. New and/or updated signaling may be introduced to enable a transmitter, e.g., an access point (AP), to include information/signaling in the preamble or in other frames. A receiver (e.g., a wireless station) that receives this information/signaling may accordingly determine in which RU it should decode to receive its allocated data or payload, allowing multiple receivers or STAs to share a single resource unit (RU). The new/updated signaling may include modified hybrid downlink multiuser signaling in Ultra High Reliability Signal (UHR-SIG), a group association identifier (gAID), a predefined special AID corresponding to an RU with use of a Bloom filter, multiple predefined special AIDs each corresponding to a non-overlapping group of wireless stations, and/or signaling announcing time sharing of single RUs.

    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 transmit, periodically, an advertisement packet on an advertisement channel associated with a UWB channel. The device may transmit, according to a UWB channel usage pattern indicated by the advertisement packet, on the UWB channel. The advertisement packet may include a UWB transmit start time offset, a UWB transmit duration, a UWB transmit interval, information to determine a UWB transmit interval, and/or a UWB transmission type.

    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: 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: 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.
