METHOD AND APPARATUS FOR ENABLING EMLSR OPERATION WITH TWT OVER MULTIPLE LINKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18054526 titled 'METHOD AND APPARATUS FOR ENABLING EMLSR OPERATION WITH TWT OVER MULTIPLE LINKS

Simplified Explanation

The patent application describes methods and apparatuses for enabling the coexistence of target wake time (TWT) and enhanced multi-link single radio (EMLSR) operations for multi-link devices (MLDs). Here are the key points:

  • The invention focuses on non-access point (AP) MLDs, which consist of multiple stations (STAs) and a processor.
  • Each STA has a transceiver to establish a link with a corresponding AP of an AP MLD.
  • Some of the links are EMLSR links, which provide enhanced multi-link capabilities.
  • TWT schedules are created for communication on at least two of the EMLSR links, with each having a TWT service period (SP).
  • The processor determines if there is an overlap between the TWT SP of the first EMLSR link and other TWT SPs of other EMLSR links.
  • If an overlap exists, the first EMLSR link is prioritized based on criteria related to each TWT schedule.
  • The prioritized EMLSR link initiates a frame exchange.

Potential applications of this technology:

  • Wireless communication systems with multi-link devices.
  • Networks where coexistence of TWT and EMLSR operations is required.
  • Environments with non-AP MLDs that need to establish links with AP MLDs.

Problems solved by this technology:

  • Coexistence of TWT and EMLSR operations, which were previously challenging to achieve simultaneously.
  • Efficient scheduling and prioritization of EMLSR links based on TWT schedules.
  • Ensuring smooth communication and frame exchange between non-AP MLDs and AP MLDs.

Benefits of this technology:

  • Improved coexistence and compatibility between TWT and EMLSR operations.
  • Enhanced efficiency and performance of multi-link devices.
  • Optimal utilization of resources and reduced interference in wireless communication systems.


Original Abstract Submitted

Methods and apparatuses for facilitating the coexistence of target wake time (TWT) and enhanced multi-link single radio EMLSR operations for multi-link devices (MLDs). 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. At least a subset of the links are EMLSR links. TWT schedules are established for communications on at least two of the EMLSR links, each having a TWT service period (SP). The processor is configured to determine whether there is an overlap between a first of the TWT SPs that corresponds to a first of the EMLSR links and other TWT SPs that correspond to other EMLSR links, based on the overlap existing, prioritize the first EMLSR link based on criteria related to each of the TWT schedules, and initiate a frame exchange on the prioritized EMLSR link.
