Abstract: A first device may one or more processors. The one or more processors may be configured to monitor wireless receive (Rx) traffic to a second device. The one or more processors may be configured to generate, based on the wireless Rx traffic, control information to control wireless transmit (Tx) traffic from the first device to avoid collision between the wireless Rx traffic and the wireless Tx traffic, the control information including at least one of a maximum Tx frame duration or a minimum Tx inter-frame gap. The one or more processors may be configured to wirelessly transmit, via a transceiver based on the control information, the wireless Tx traffic in a wireless local area network (WLAN).

Abstract: Systems and methods for configuring reduced repetitions for ultra-wideband (UWB) physical layer headers may include a first UWB device that generates a packet including a first header and a second header. The first header may include a plurality of bits indicating a data rate and an encoding scheme of a payload of the packet. The first UWB device may transmit the packet to a second UWB device. The second UWB device may receive and decode the packet according to the encoding scheme and the data rate.

Abstract: A first device may include one or more processors. The one or more processors may generate one or more request frames including a request for a first target wake time (TWT) schedule and a second TWT schedule. The one or more processors may wirelessly transmit, via a transmitter over a wireless local area network (WLAN), the generated one or more request frames to an access point (AP). In response to receiving from the AP one or more response frames accepting the request, the one or more processors may communicate (i) with the AP during a service period (SP) of the first TWT schedule and (ii) with a second device during an SP of the second TWT schedule.

Abstract: Disclosed herein are related to a system and a method for determining an Angle of Approach (AoA) of a device. A first device may receive a report from a second device having a plurality of ultra-wideband (UWB) devices. The report may include a plurality of values comprising an elevation component and an azimuth component of the AoA from the first device. At least some of the plurality of values may be obtained according to measurements between the plurality of UWB devices of the second devices and the at least one UWB device of the first device. The first device may determine an AoA from the second device, using the plurality of values from the report received from the second device.

Abstract: Disclosed herein are related to dynamically adjusting a wake time and a sleep time for wireless communication between two or more devices to reduce power consumption. In one aspect, a first device enters a wake up state to wirelessly communicate with a second device for a service period with a determined duration scheduled according to a target wake time (TWT) protocol. In one aspect, the first device monitors for one or more indicators from the second device indicating that additional data is available for communication. In one aspect, the first device extends the service period beyond the determined duration, in response to receiving a first indicator of the one or more indicators. In one aspect, the first device communicates with the second device the additional data during the service period extended beyond the determined duration.

Abstract: Described embodiments provide devices and methods for operating a multilink device (MLD) and a wireless node using wireless local area network (WLAN) channels and non-WLAN channels. The wireless node may transmit a first message to reserve at least a first WLAN channel. Via a non-WLAN channel, the wireless node may transmit a second message identifying the first WLAN channel to a wireless device, to cause a plurality of receivers of the wireless device to receive on the first WLAN channel. The wireless device may comprise a WLAN-based MLD. At least a defined duration after the second message, the wireless node may transmit at least one data frame to the plurality of receivers of the wireless device, via the first WLAN channel.
