Request for Multi-Access Point Target Waketime Information

Abstract

The first access point (AP) sends a first frame to the second AP requesting the second AP's first limited target wake time (R-TWT) information, based on the fact that it has not received the second AP's beacon frame within a first period from the second AP's target beacon transmission time (TBTT). In response to the first frame, the first AP receives a second frame from the second AP containing the second AP's first R-TWT information. The first AP receives a third frame from the second AP containing the second AP's second R-TWT information and a second R-TWT change count.
