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.

Abstract: Certain aspects of the present disclosure provide techniques for handling direct link communications in multi-link systems. An example method generally includes transmitting, to a first wireless station via a direct link between the first wireless station and one or more second wireless stations affiliated with a multi-link device (MLD), a data frame comprising a transmitter address field set to an address of the MLD, which is one of a plurality of addresses associated with the MLD and the second wireless stations being affiliated with the MLD for multi-link operations. The method also includes communicating with the first wireless station via the direct 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, components, devices and systems for performing actions related to maximum allowed and active links at an access point (AP) multilink device (MLD) for each client. An example method performed by an AP MLD includes outputting, for transmission, a first frame indicating at least one of: a first limit on an allowed number of links for association with a multi-link device (MLD) with which the apparatus is affiliated, or a second limit on a number of allowed active links, obtaining, from a client, a request to associate one or more links between the client and the AP MLD, and processing the request subject to at least the first limit.

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: Aspects relate to wireless communication at a wireless communication device. The wireless communication device may include a transmitter configured to communicate using a first communication protocol, a receiver configured to communicate using a second communication protocol, different from the first communication protocol, a first antenna coupled to the transmitter, a second antenna coupled to the receiver and physically separated from the first antenna by a variable distance. The wireless communication device transmits, via the first antenna, a first transmission within a first frequency range, and receives via the second antenna, a second transmission within a second frequency range that overlaps the first frequency range. To receive the second transmission, the device may perform a radio frequency coexistence mitigation procedure based on the variable distance between the first antenna and the second antenna in response to detection of a concurrency in time between the first transmission and the second transmission.
