Abstract
Embodiments of a method and device for multi-link communications are disclosed. In an embodiment, a method of multi-link communications involves, at a multi-link STA device (STA MLD) that supports a first link, link1, and a second link, link2, receiving a beacon on link2, acquiring an updated critical operating parameter for link1 in response to the beacon received on link2, and operating link1 according to the acquired updated critical operating parameter.
Claims19
A method of multi-link communications, the method comprising:
- at a multi-link STA device (STA MLD) that supports a first link, link1, and a second link, link2,
- receiving from an access point (AP) MLD a beacon on link2 that includes an announcement that link1 has a critical operating parameter;
- transmitting, by the STA MLD, a Probe Request in response to the announcement included in the beacon received on link2, wherein the Probe Request solicits a Probe Response, and wherein the Probe Response carries the critical operating parameter for link1;
- receiving, by the STA MLD, the Probe Response, wherein the Probe Response carries the critical operating parameter for link1;
- acquiring the critical operating parameter for link1 via the received Probe Response;
- operating link1 according to the acquired critical operating parameter;
- selecting, by the STA MLD, a first listen interval, ListenInterval1, and a first beacon interval, BeaconInterval1, for link1, and a second listen interval, ListenInterval2, and a second beacon interval, BeaconInterval2, for link2;
- and
- receiving, by the STA MLD, a buffered frame information announcement of link1 in the beacon on link2 with an interval that is at least one of floor(ListenInterval1/BeaconInterval2) and ceiling(ListenInterval1/BeaconInterval2).

A multi-link STA device (STA MLD), the STA MLD comprising:
- a processor configured to:
- communicate with an access point (AP) MLD via a first link, link1, and a second link, link2;
- receive from the AP MLD a beacon on link2 that includes an announcement that link1 has a critical operating parameter;
- transmit a Probe Request in response to the announcement included in the beacon received on link2, wherein the Probe Request solicits a Probe Response that will carry the critical operating parameter for link1;
- receive the Probe Response, wherein the Probe Response carries the critical operating parameter for link1;
- acquire the critical operating parameter for link1 via the received Probe Response;
- operate link1 according to the acquired critical operating parameter;
- select, by the STA MLD, a first listen interval, ListenInterval1, and a first beacon interval, BeaconInterval1, for link1, and a second listen interval, ListenInterval2, and a second beacon interval, BeaconInterval2, for link2;
- and
- receive, by the STA MLD, a buffered frame information announcement of link1 in the beacon on link2 with an interval that is at least one of floor(ListenInterval1/BeaconInterval2) and ceiling(ListenInterval1/BeaconInterval2).
