Abstract
An access point (AP) multi-link device (MLD) transmits, to a station (STA) MLD, a first frame indicating a first start time of a target wake time (TWT) service period (SP) scheduled on a first link between the AP MLD and the STA MLD. The AP MLD transmits, to the STA MLD, on a second link between the AP MLD and the STA MLD, a second frame indicating a second start time of the TWT SP on the first link, where the second start time is based on a cross-link switching delay associated with the STA MLD.
Claims20
An access point (AP) multi-link device (MLD) comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the AP MLD to:
- transmit, to a station (STA) MLD, a first frame indicating a first start time of a target wake time (TWT) service period (SP) scheduled on a first link between the AP MLD and the STA MLD;
- and
- transmit, to the STA MLD, on a second link between the AP MLD and the STA MLD, a second frame indicating a second start time of the TWT SP on the first link, wherein the second start time is based on a cross-link switching delay associated with the STA MLD.
A station (STA) multi-link device (MLD) comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the STA MLD to:
- receive, from an access point (AP) MLD, a first frame indicating a first start time of a target wake time (TWT) service period (SP) scheduled on a first link between the AP MLD and the STA MLD;
- and
- receive, from the AP MLD, on a second link between the AP MLD and the STA MLD, a second frame indicating a second start time of the TWT SP on the first link, wherein the second start time is based on a cross-link switching delay associated with the STA MLD.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause an access point (AP) multi-link device (MLD) to:
- transmit, to a station (STA) MLD, a first frame indicating a first start time of a target wake time (TWT) service period (SP) scheduled on a first link between the AP MLD and the STA MLD;
- and
- transmit, to the STA MLD, on a second link between the AP MLD and the STA MLD, a second frame indicating a second start time of the TWT SP on the first link, wherein the second start time is based on a cross-link switching delay associated with the STA MLD.
