    摘要： Methods, apparatuses, and computer readable media for communicating elements between multi-link devices are disclosed. Apparatuses of a first access points (AP) of an AP multi-link device (MLD) are disclosed, where the apparatuses comprise processing circuitry configured to encode a first portion of a first beacon frame or first response frame, and in response to a second AP of the AP MLD transmitting, on a second frequency band, a second beacon frame or a second probe response frame comprising a channel switch announcement element or an enhanced channel switch announcement frame, encoding a second portion of the first beacon frame or the first probe response frame, the second portion comprising the channel switch announcement element or the enhanced channel switch announcement frame. The processing circuitry is further configured to configure the first AP of the AP MLD to transmit, on a first frequency band, the first beacon frame.

    摘要： A non-AP STA of a multi-link device (STA MLD) may be configured to encode a multi-link (ML) probe request frame for transmission to an access point STA (AP) of an AP MLD comprising a plurality of affiliated APs. When the probe request frame is sent outside the context of active scanning, to discover an AP of the AP MLD the ML probe request frame may be encoded to have an Address 1 field set to a broadcast address and an Address 3 field set to a BSSID of the AP, or encoded to have the Address 1 field set to a basic service set identity (BSSID) of the AP's BS. The non-AP STA may refrain from transmitting the ML probe request frame to the AP of the AP MLD in a corresponding link when another non-AP STA of the AP MLD has already received a ML probe response that included complete information from any one of the APs of the AP MLD in any link.

    摘要： Multi-link device (MLD) security association (SA) query and query response procedures are described. Any of the links between an access point (AP) MLD and a non-AP MLD may be used to initiate association, reassociation, or disassociation procedures using the SA query requests and responses. The SA query request or response from one of the stations (STAs) associated with the MLD is sent to a corresponding linked one of the STAs associated with the other MLD. The SA request or response is addressed to the other MLD rather than the STA of the other MLD. Retry timeouts and maximum timeouts for resending SA query requests are set by the AP MLD and the same across each of the links.

    摘要： Methods, apparatuses, and computer readable media for communicating elements between multi-link devices are disclosed. Apparatuses of a first station (STA) affiliated with a multi-link device (MLD) are disclosed, where the apparatuses comprise processing circuitry configured to determine a sequence number as a next sequence number of a sequence number space where the sequence number space is indexed by a MLD media access control (MAC) address of a second MLD, and wherein the processing circuitry is further configured to encode a media access control (MAC) management protocol data unit (MMPDU) in a physical layer (PHY) protocol data unit (PPDU), the MMDPU including the sequence number, a frame body, and an address 1 field, the address 1 field indicating an address of a second station (STA) affiliated with the second MLD, and configure the first STA to transmit the PPDU to the second station.
