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: Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to an apparatus for wireless communications. The apparatus generally includes an interface for communicating with a plurality of wireless nodes via a plurality of antennas, and a processing system configured to determine a power state of each of the plurality of wireless nodes, and change from a first antenna mode used for communicating with the wireless nodes using a first number of spatial streams to a second antenna mode used for communicating with the wireless nodes using a second number of spatial streams, based on the determined power states of the wireless nodes.

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 performing passive scanning operations on one or more wireless channels. In some implementations, a wireless communication device configures an off-channel scan time and a passive scanning period for passive scanning operations based on latency requirements of a low-latency application, and selects a home channel dwell time for the passive scanning operations. The wireless communication device may perform the passive scanning operation by alternating between listening for beacon frames on one or more second wireless channels for the configured off-channel scan time and dwelling on a home channel for the selected home channel dwell time during a first portion of the configured scanning period. The wireless communication device also may listen for beacon frames on the one or more second wireless channels during a second portion of the configured scanning period that is defined by the selected home channel dwell time.
