Abstract
Session recovery after network coordinator or AP restart for single user, multiple user, multiple access, and/or MIMO wireless communications. Restart or reset of a network coordinator (e.g., an access point (AP) or other network coordinator type device) may occur for various reasons (e.g., a power cycle or power failure, inadequate failover protection, scheduled or planned power outages such as for including network maintenance, software upgrades, etc.). Upon determination of network coordinator restarted or reset, a singular bit within a communication from the network coordinator indicates synchronization or not of the its timing synchronization function (TSF) (e.g., with other devices in the communication system, such as wireless stations (STAs), smart meter stations (SMSTAs), etc.). A given device (e.g., STA, SMSTA, etc.) can provide its current TSF to the network coordinator so that it can resynchronize, re-establish its scheduled for wake times of those devices (e.g., target wake times (TWTs)), etc.
