METHOD AND APPARATUS FOR USING AAR TO SUPPORT EMLSR OPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17935040 titled 'METHOD AND APPARATUS FOR USING AAR TO SUPPORT EMLSR OPERATION

Simplified Explanation

The patent application describes methods and apparatuses for improving the operation of multi-link devices (MLDs) in a wireless local area network. Specifically, it focuses on facilitating recovery from loss of medium synchronization and renegotiating traffic identifier (TID)-to-link mapping for enhanced multi-link single radio (EMLSR) operation of MLDs.

  • The patent application is about improving the performance of multi-link devices (MLDs) in a wireless local area network.
  • It focuses on recovering from loss of medium synchronization and renegotiating traffic identifier (TID)-to-link mapping for enhanced multi-link single radio (EMLSR) operation of MLDs.
  • The invention involves a non-access point (AP) MLD that consists of multiple STAs (stations) and a processor.
  • The STAs have transceivers that form links with corresponding APs of an AP MLD.
  • A subset of the links are EMLSR links, which operate in an EMLSR mode of operation.
  • The processor is responsible for generating a request for AP-assisted medium synchronization recovery (AAR) for a set of EMLSR links when an EMLSR frame exchange sequence is detected on a first EMLSR link.
  • The request for AAR is transmitted to the AP MLD by one of the transceivers.

Potential Applications

  • Wireless local area networks (WLANs)
  • Multi-link devices (MLDs)
  • Enhanced multi-link single radio (EMLSR) operation

Problems Solved

  • Loss of medium synchronization in multi-link devices (MLDs)
  • Renegotiating traffic identifier (TID)-to-link mapping in MLDs
  • Ensuring efficient operation of EMLSR links in a wireless local area network

Benefits

  • Improved performance and reliability of multi-link devices (MLDs)
  • Enhanced recovery from loss of medium synchronization
  • Efficient renegotiation of traffic identifier (TID)-to-link mapping
  • Better utilization of EMLSR links in a wireless local area network


Original Abstract Submitted

Methods and apparatuses for facilitating recovery from loss of medium synchronization for multi-link devices (MLDs) and renegotiating traffic identifier (TID)-to-link mapping for enhanced multi-link single radio (EMLSR) operation of MLDs in a wireless local area network. A non-access point (AP) MLD comprises STAs, each comprising a transceiver configured to form a link with a corresponding AP of an AP MLD, and a processor operably coupled to the STAs. A subset of the links are EMLSR links that are configured to operate in an EMLSR mode of operation. The processor is configured to generate, based on a determination that an EMLSR frame exchange sequence is occurring on a first one of the EMLSR links, a request for AP-assisted medium synchronization recovery (AAR) for a set of the other EMLSR links. At least one of the transceivers is further configured to transmit, to the AP MLD, the request for AAR.
