Abstract: A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) is associated with a primary link and a non-primary link. The NSTR softAP MLD transmits, on only the primary link, a frame including a complete profile of the primary link and indicating a complete profile of the non-primary link. The respective complete profiles of the primary link and the non-primary link each include capabilities, operation parameters, and other discovery information. The frame can include fields and elements that carry the complete profile of the primary link, and can include a multi-link (ML) element that indicates the complete profile of the non-primary link. The NSTR softAP MLD can receive or determine an update to the operation parameters of the non-primary link, and can transmit, on the primary link, an indication of the update to the operation parameters of the non-primary link.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for high frequency multi-link support systems operation. In some aspects, an access point (AP) multi-link device (MLD) and a non-AP MLD may use a first radio frequency link to support and facilitate communications using a second radio frequency link, where such a second radio frequency link may otherwise be associated with access constraints or difficulties. For example, the first radio frequency link may be a sub-7 gigahertz (GHz) link and the second radio frequency link may be a 3.5 GHz, 45 GHz, or 60 GHz link. The AP MLD may transmit, to the non-AP MLD via the first radio frequency link, identifying and control information associated with the second radio frequency link. The non-AP MLD and the AP MLD may use the identifying and control information to communicate data via the second radio frequency link.

Abstract: A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) associated with a primary link and a non-primary link determines that the non-primary link is unavailable, and transmits, on only the primary link, a frame carrying an indication of the unavailability of the non-primary link. The NSTR softAP MLD may set a Do Not Transmit (DNT) bit to a value of 1 and may operate as a single-link device on the primary link based on the unavailability of the non-primary link. In some instances, the NSTR softAP MLD determines that the non-primary link is available while operating as the single-link device on the primary link, resets the DNT bit based on the availability of the non-primary link, and transmits the reset DNT bit in another frame on only the primary link.

Abstract: This disclosure provides methods, devices and systems for providing energy detection based resolution in radio access technologies. In one aspect, a wireless communication device may include a first energy detection threshold (EDT) to identify a transmission opportunity in an unlicensed frequency band. The wireless communication device may detect a second wireless communication device having a second EDT to identify the transmission opportunity, the second EDT being greater than the first EDT. The wireless communication device may, based on detection of the second wireless communication device having the second EDT, modify a transmission configuration of the first wireless communication device.

Abstract: This disclosure provides methods, components, devices and systems for flexible beacon interval operation. Some aspects more specifically relate to inclusion of indications of static and dynamic beacon intervals in beacon frames, and other frames. In some examples, an AP may transmit a frame including multiple indications of multiple beacon intervals, such as an indication of a static beacon interval and an indication of a dynamic beacon interval. The AP may then transmit frames, such as beacon frames, at times associated with the beacon intervals.

Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications during restricted target wake time (r-TWT) service periods (SPs). Some implementations more specifically relate to coordinated scheduling of r-TWT SPs between OBSSs. In some aspects, a first AP may coordinate with a second AP in scheduling r-TWT SPs so that latency-sensitive traffic in a first BSS does not interfere or collide with latency-sensitive traffic in a second BSS overlapping the first BSS. In some implementations, the first and second APs may schedule their respective r-TWT SPs to be orthogonal in time. In some other implementations, the first and second APs may schedule their r-TWT SPs to overlap in time, while allocating coordinated resources to concurrent or overlapping latency-sensitive traffic in the first and second BSSs (such as in accordance with one or more multi-AP coordination techniques).

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) may transmit a packet, at the beginning of a restricted TWT SP, that signals all non-member wireless stations (STAs) to defer access to the wireless medium for at least a threshold duration. Upon receiving the packet, any non-member STAs that are associated with the AP may set their network allocation vectors (NAVs) according to the duration indicated by a duration field of the received packet. In some implementations, low-latency STAs that are members of the TWT SP may not set their NAVs according to the duration field of the received packet. Instead, the low-latency STAs may access the wireless medium before the NAVs associated with the non-member STAs expire.

Abstract: This disclosure provides methods, components, devices and systems for signaling mechanisms for multi-hop channel sounding for relay operation. Some aspects more specifically relate to frame addressing and transmission opportunity (TXOP) or service period (SP) sharing to facilitate a multi-hop channel sounding within a single TXOP or SP. An originating device may transmit a first frame indicating identifying information corresponding to multiple other wireless communication devices to initiate a multi-hop channel sounding involving the multiple other wireless communication devices. For example, the originating device may include, in the first frame, identifying information corresponding to a satellite access point (AP) and identifying information corresponding to an end device with which the originating device may communicate via the satellite AP. In accordance with the multi-hop channel sounding, the originating device may receive, collectively via one or more frames, channel information associated with each hop between the originating device and the end device.

Abstract: In some implementations, a first access point (AP) selects one or more other APs for participation with the first AP in a coordinated access point transmission session. The first AP obtains a transmission opportunity (TXOP), and transmits a frame indicating scheduling information for uplink (UL) or downlink (DL) transmissions to or from the selected APs, the scheduling information indicating a respective start time for the UL or DL transmissions to or from the selected APs, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. The first AP transmits or receives wireless packets to or from one or more associated stations (STAs) at least partially concurrently with the transmission or reception of wireless packets by the selected APs to or from their respective associated STAs based on the scheduling information.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless communication device may determine a first set of parameters for communicating with a second wireless communication device within a first set of time intervals, the first set of parameters associated with a beamforming procedure. The first wireless communication device may predict, based on inputting the first set of parameters to a machine learning model, a second set of parameters corresponding to a second set of time intervals in the future after the first set of time intervals. The first wireless communication device may select a beamforming configuration for communications between the first wireless communication device and the second wireless communication device based on the second set of parameters, and may communicate with the second wireless communication device within the second set of time intervals in accordance with the beamforming configuration.
