Abstract
One example discloses a multi-link device (MLD) within a wireless local area network (WLAN), including: a controller configured to generate a management frame having a set of multi-link information elements (ML IEs); wherein the MLD is configured to be coupled to a set of PHY-layer links; and wherein the controller is configured to perform a multi-link setup with a second MLD using the set of ML IEs over the PHY-layer links.
Claims11
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.
A method for multi-link setup between a first Multi-Link Device (MLD) and a third Multi-Link Device (MLD), comprising:
- receiving, by a second MLD, a request frame from the first MLD for multi-link setup with the 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;
- wherein the multi-link setup is defined by the set of ML IEs;
- and
- transmitting, by the second MLD, a response frame, that 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.
