Abstract: Systems and methods are provided for enhancing the concurrency of a wireless device operating in multiple network contexts. By identifying opportunity instants that may exist within the normal exchange of information by a device having a single physical transceiver in a first network context, tasks for a second network context may be performed using the transceiver with minimal impact on performance related to the first network context and preferably in complete transparence to the first network context.

Abstract: This disclosure relates to multi-link communications in wireless communication networks. Some aspects more specifically relate to conflict mitigation techniques for enhanced multi-link single-radio (EMLSR) links between multi-link devices. In some examples, an access point (AP) multi-link device (MLD) and a non-AP MLD may communicate via two enhanced multi-link single-radio (EMLSR) links, one of which may be an anchor link of the non-AP MLD. In some examples, the non-AP MLD may maintain a beacon drop count representing a number of beacons that it has dropped on its anchor link since its last successful receipt of a beacon. In some examples, when the beacon drop count satisfies a beacon drop threshold, the non-AP MLD may transmit a packet on the non-anchor link to initiate a communication pause for the non-anchor link, so that it can receive a beacon on the anchor link.

Abstract: This disclosure describes a power save mechanism for devices in a neighbor awareness networking (NAN) network. In some aspects, a NAN device is able to enter into a power save mode during a window agreed to between the NAN device and a NAN peer device. A NAN device transmits, to a NAN peer device, an indication that the wireless communication device is to enter a power save mode. For example, the NAN device may transmit a MAC packet with a more data (MD) bit set to 0. The NAN peer device may indicate that the NAN device is allowed to enter the power save mode by transmitting a MAC packet with the MD bit set to 0, or the NAN peer device may indicate that the wireless communication device is not to enter the power save mode by transmitting a MAC packet with the MD bit set to 1.

Abstract: This disclosure provides methods, components, devices and systems for operation expansion policy framework for access points (APs). An example method, performed by a first wireless node, includes outputting, for transmission, information that indicates at least one of (i) one or more criteria that, when met by a second wireless node, indicate the second wireless node is allowed to request that the first wireless node modify one or more wireless operating parameters, or (ii) one or more options for modifying the wireless operating parameters of the first wireless node, obtaining a first request that requests the first wireless node to modify the wireless operating parameters, and processing the first request based on the information.

Abstract: This disclosure provides methods, components, devices and systems for performing actions to protect a wireless access point (AP) from repeated incorrect security credential input attacks. For example, a combination of techniques are implemented to block a wireless station (STA) from submitting innumerable number of incorrect security credential inputs to connect to the wireless AP by using embargo lists to block the wireless STA media access control (MAC) address after N number of consecutive unsuccessful attempts to connect to the wireless AP, using telescopic delays to make it progressively harder for the wireless STA to attack (that is, repeatedly submit incorrect security credential inputs) at regular short intervals, and/or determining position of the wireless STA of the attacker and then block attacks from all wireless STAs at the determined location.

Abstract: Certain aspects of the present disclosure provide an architecture and method for multi-link operation (MLO) at an access point (AP). The method generally includes obtaining a packet from at least one buffer and selecting a processing path, from first and second processing paths, for a packet to be routed from the at least one buffer to at least one of a plurality of radio components for wireless transmission to at least one peer via one or more links, wherein: the first processing path is configured to bind the packet to one of the one or more links based on at least one code-implemented rule, and the second processing path is configured to bind the packet to one of the one or more links based on instantaneous channel sensing.

Abstract: This disclosure provides systems, methods and apparatus for asynchronous channel access control of a wireless system. In some aspects, a device may adjust the priority of one or more PPDUs and may perform other operations to ensure control of a wireless medium at certain times while still allowing for other devices to communicate on the wireless medium. For example, the device may adjust a backoff counter or one or more EDCA parameters to ensure obtaining control of the wireless medium to transmit a first PPDU of an application file. For one or more subsequent PPDUs of the application file, the device may again adjust a backoff counter or one or more EDCA parameters to allow other devices to obtain control of the wireless medium in certain scenarios (such as a second device to provide information back to the device or to otherwise transmit using the shared wireless medium).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an access point may start a target wake time (TWT) service period (SP). The access point may receive an end of SP (EOSP) indication from a station. The access point may stop the TWT SP before a scheduled end of the TWT SP based on receiving the EOSP indication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a sensing device may transmit a first Layer 2 (L2) data packet that includes a Layer 2.5 (L2.5) frame. The sensing device may receive a second L2 data packet that includes a response to the L2.5 frame. Motion data indicating whether an object is moving may be generated based at least in part on a channel frequency response associated with receiving the second L2 data packet. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses for wireless communications. In some implementations, a first wireless communication device associated with a basic service set (BSS) receives a plurality of packets transmitted during a measurement window by a second wireless communication device associated with the BSS. The first wireless communication device determines a received signal strength indicator (RSSI) value of the plurality of received packets, determines a level of overlapping basic service set (OBSS) interference on the wireless medium during the measurement window, and adjusts one or more of a packet detect (PD) threshold, an OBSS PD threshold, or an energy detect (ED) threshold based on the determined RSSI value and the level of OBSS interference.
