Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing discovery frames and group addressed frames communication. For example, some embodiments relate to a method including generating a first frame to be transmitted to a first electronic device. An association identifier (AID) value of the first frame is set to a first value to indicate that the first frame is an individually addressed frame addressed to the first electronic device. The method further includes generating a second frame to be transmitted to a group of one or more electronic devices. An AID value of the second frame is set to a second value different from the first value. The method also includes transmitting the first frame and the second frame.

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: Embodiments are disclosed for one-to-many and many-to-many ranging using narrowband assisted (NBA)-multi-millisecond (MMS) ultra wideband (UWB) protocols. Some embodiments include an initiator device that communicates with many responder devices. For example, the initiator device can transmit a control/initialization poll message via NB signaling that identifies a ranging cycle, and transmit a first set of MMS segments corresponding to the control/initialization poll message. The initiator device can receive a plurality of report frames from two or more responder devices via NB signaling subsequent to transmitting the first set of MMS segments, and transmit within the ranging cycle, a ranging results report message based at least on the plurality of report frames via narrowband signaling.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing a hibernation mode for multi-link wireless communication networks such as a wireless local area network (WLAN). For example, some aspects relate to a multi-link device (MLD) including a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link. The MLD also includes a second STA associated with a second link of the wireless network. The second STA is in a hibernation mode. The MLD also includes one or more processors communicatively coupled to the first and second STAs and configured to control operations of the first and second STAs.

Abstract: Embodiments are disclosed for encrypting media access control (MAC) Header fields for Wireless LAN (WLAN) privacy enhancement. For example, a transceiver of a station (STA) or an access point (AP) can set a real time Media Access Control (MAC) header bit in a payload of an aggregated MAC Protocol Data Unit (A-MPDU) subframe to an actual value of a power management (PM) field of a MAC header of the A-MPDU subframe. The transceiver can encrypt the payload, set the PM field to an over the air (OTA) PM value, and transmit the A-MPDU subframe over the air. The OTA PM value can include all zeros, a predetermined value, or a randomized value The transceiver can also set static MAC header bits in the payload of the A-MPDU subframe to corresponding actual values of an aggregated MAC service data unit (A-MSDU) present field of the A-MPDU subframe.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing block acknowledgment (BA) operations for multi-link wireless communication networks. 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 transmit, using the transceiver and to a second electronic device, a first set of one or more frames on a first link and a second set of one or more frames on a second link. The one or more processors receive, using the transceiver and from the second electronic device, a first block acknowledgment (BA) frame on the first link and a second BA frame on the second link. The one or more processors further determine, based on received first BA frame and the second BA frame, a failed or missing frame of the first set of one or more frames transmitted on the first link.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing address and parameter modifications for an access point (AP) and/or a station (STA). Some aspects of this disclosure relate to an electronic device. The electronic device includes a transceiver and a processor communicatively coupled to the transceiver. The processor is configured to communicate, using the transceiver, with a second electronic device that is associated with the electronic device using a first address and a first parameter of the electronic device. The processor is further configured to determine a second address and a second parameter for the electronic device, where the second address is different from the first address and the second parameter is different from the first parameter. The processor is further configured to communicate with the second electronic device using the second address and the second parameter.

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: A multilink access point may communicate with a legacy device. The multilink access point identifies an attempt, by at least one legacy station, to connect to the access point, determines that the at least one legacy station does not support multilink communications, broadcasts a beacon identifying information for a basic communication link that can be used by the at least one legacy station and associates with the at least one legacy station based at least on information included in the beacon, wherein the at least one legacy station communicates exclusively on the basic communication link with the access point.
