TECHNIQUES FOR IMPLICIT INDICATION OF TRIGGER FRAME START TIMES

摘要

Techniques for implicit indication of trigger frame start times are described. In various embodiments, an AP may be configured to transmit a trigger frame at the beginning of each target wake time (TWT) interval. In some embodiments, each STA that uses a given TWT interval may be configured to treat a TWT Start Time received from the AP not only as a start time for that TWT interval but also as a start time for the trigger frame to be received from the AP. In various embodiments, each STA in a TWT Group may wait to receive the trigger frame from the AP upon awakening during its TWT interval. The embodiments are not limited in this context.

主权项

1. An apparatus, comprising:
at least one memory; and logic, at least a portion of which is in hardware, the logic to receive a beacon frame comprising a start time for a target wake time (TWT) interval assigned to a station (STA), transition the STA from a sleep state into an awake state at or before the start time for the TWT interval, and defer contending for access to a wireless channel during the TWT interval until a receipt of a trigger frame from an access point (AP).
