Abstract: Various aspects provide a wireless station (STA) to implement congestion sensitive target wake time (TWT) communications scheduling and enable the STA to determine whether to engage in communications between TWT service periods. A method described includes identifying a congestion metric, determining whether the congestion metric meets a congestion threshold, and transmitting a request to establish TWT communications in response to determining that the congestion metric meets the congestion threshold. Another method described includes terminating a scheduled service period of a TWT communications, receiving an indication that a threshold number of frames is available for transmission to an STA from an access point (AP) or an indication that one or more frames are present in a transmission queue at the STA, and transmitting, by the STA to the AP an indication that a communications link is to remain active between the terminated scheduled service period and a subsequent scheduled service period.
