Abstract: Embodiments are disclosed for triggered multi-link (ML) access coordination. A station (STA) ML device (MLD) can establish a preferred triggering link (PTL) with an access point (AP) MLD where the PTL is the preferred link for receiving triggering frames. The STA MLD can transmit uplink (UL) frames via the PTL in response to a trigger frame. Subsequently, the STA MLD can determine that the PTL is busy, and transmit enhanced distributed channel access (EDCA) UL frames on a non-PTL link. In a power save mode, the STA MLD can use the PTL to exchange UL and downlink (DL) frames. Multiple PTLs can be established supporting concurrent trigger frames, and different ranges of traffic IDs (TIDs) can be used for each PTL. The STA MLD can utilize AP MLD link pair information to receive a DL retransmission corresponding to one TID via both links of the AP MLD link pair.

Abstract: A bandwidth-limited client station is configured to operate with a maximum bandwidth that is less than a full bandwidth of a communication channel of a wireless local area network. The bandwidth-limited client station negotiates a target wake time (TWT) period with an access point, including negotiating a particular non-primary component channel among one or more non-primary component channels in which the bandwidth-limited client station is expected to operate during the TWT period. The bandwidth-limited client station receives a first legacy packet from the access point in the particular non-primary component channel, the first legacy packet including a beacon frame. The bandwidth-limited client station also receives a trigger frame from the access point in a second legacy packet in the particular non-primary component channel during the TWT period.
