Abstract: Examples of wireless communication based on link use capabilities of multi-link devices is disclosed. A first multi-link device receives a first physical layer conformance procedure (PLCP) protocol data unit (PPDU) on a first link from a second multi-link device and transmits a second PPDU on the second link based on a link use capability of the second multi-link device and a backoff counter counting down to a predetermined value. A first multi-link device also transmits a PPDU on the first link and the second link at a same start time based on an link idle determination and the backoff counter counting down to a predetermined value.

Abstract: A method for securing a multi-band wireless communication system includes authenticating a first station (STA) multi-link device (MLD) with a second STA MLD comprising negotiating a group of keys in a key negotiation (KN) band, the group of keys comprising a Pair-Wise Transient Key and a Group Transient Key. The KN band is one of a plurality of frequency bands. The first STA MLD includes a plurality of first STA links. The second STA MLD includes a plurality of second STA links. Each of first STA links and each corresponding second STA link are configured to transceive over a respective one of the plurality of frequency bands. Authenticating the first STA MLD in the KN band authenticates the first STA MLD for each of the frequency bands.

Abstract: A first communication device determines an amount of data queued at the first communication device for transmission. When a control field is to be generated according to a first format, the first communication device determines a scaling value (SV) and an unscaled value (UV) corresponding to the determined amount of data queued for transmission such that a result of SV multiplied by BV indicates the determined amount of data queued for transmission, and generates the control field to include i) a scaling factor subfield set to indicate the SV, and ii) an unscaled queue size subfield set to indicate the BV. When the control field is to be generated according to a second format, the first communication generates the control field to include a queue size subfield set to indicate the determined amount of data queued for transmission and such that the control field does not include the scaling factor subfield.
