Abstract
A station may be scheduled for a trigger-enabled restricted target wake time service period (TE r-TWT SP). Contention-based channel access may be enabled for the station during TE r-TWT SP based on the station not receiving a first frame during a first time period of the TE r-TWT SP. The enabled contention-based access may be suspended and/or maintained based on receipt of one or more frames by the station.
Claims20
A method comprising:
- sending, by an access point (AP) to a station (STA), a first frame indicating a trigger-enabled (TE) restricted target wake time (r-TWT) service period (SP) for the AP and the STA;
- receiving, by the AP from the STA, a non-trigger-based frame during the TE r-TWT SP;
- and
- sending, by the AP to the STA, a second frame for suspending contention-based channel access by the STA during the TE r-TWT SP.

- sending, by the STA to the AP, a non-trigger-based frame during the TE r-TWT SP;
- receiving, by the STA from the AP, a second frame during the TE r-TWT SP;
- and

A method comprising:
- receiving, by a station (STA) from an access point (AP), a first frame indicating a trigger-enabled (TE restricted target wake time (r-TWT) service period (SP) for the AP and the STA,
- enabling, based on a trigger-frame not being received from the AP during a first time period, contention-based channel access for the STA during the TE r-TWT SP;
- receiving, after the first time period from the AP, a second frame;
- and
- disabling, based on the receiving the second frame, the contention-based channel access for the STA during the TE r-TWT SP.
