1. A first multi-link device (MLD) within a wireless local area network (WLAN), comprising:
a controller configured to transmit a request frame to a second MLD;
wherein the second MLD includes an established set of links with a third MLD;
wherein the request frame from the first MLD includes a set of multi-link information elements (ML IEs) that request a set of information elements to be reported on at least one of the second MLD's established links with the third MLD;
wherein the set of information elements is less than a complete set of information elements for the at least one of the links with the third MLD; and
wherein in a response frame the second MLD reports on the requested set of information elements;
wherein the ML IEs include a set of common IEs, wherein the set of common IEs includes a multi-link control IE, and wherein the multi-link control IE includes an MLSR multi-link single-radio) indication subelement, an ESRMR (enhanced single-radio multi-radio) indication subelement, an ESRMR MCS (Modulation and Coding Scheme) Nss number of spatial streams) Present subelement, a low latency support subelement, a low latency link ID (identifier) subelement, and a ML maximal MPDU (MAC Protocol Data Unit) length subelement.
