Abstract: The disclosure relates to techniques to extend the time that wireless devices spend in a sleep state. For example, a first wireless device may transmit a poll message to a second wireless device during a current polling period having multiple polling slots allocated to transmissions by the first wireless device. In response to receiving a null response message while there are one or more remaining polling slots allocated to transmissions by the first wireless device, the first wireless device may terminate the current polling period early. Furthermore, an early termination message may be transmitted to the second wireless device to indicate that the first wireless device will not be sending any further transmissions in the current polling period. As such, both wireless devices may then place one or more electronic circuits into a low-power mode prior to a sleep period scheduled to start when the current polling period ends.
