Abstract: The present disclosure relates to multi-link devices (MLDs) including access point (AP) MLDs and non-AP MLDs, and specifically modules, systems and methods for changing a first communication link between a first affiliated station (STA) of a non-AP MLD and a first affiliated AP of an AP MLD to a second communication link between the first affiliated STA of the non-AP MLD and a second affiliated AP of the non-AP MLD, while maintaining a third communication link between a second affiliated STA of the non-AP MLD and a third affiliated AP of the AP MLD. More specifically, the present disclosure provides modules, systems and methods for changing an association of a communication link independent of other communication links allowing for continuous connectivity between a non-AP MLD and an AP MLD.

Abstract: The present disclosure provides methods and apparatus related to NDPA frame indication. An aspect of the disclosure provides a method. The method includes sending, to one or more stations (STAs), a request for channel state information (CSI). The request includes a null data packet announcement (NDPA) frame including a first field and a second field. The first field indicates presence of the second field, and the second field indicates a variant of the NDPA frame. The method further includes receiving, from the one or more STAs, a CSI feedback response based on the request. In some embodiments, the first field is one of a sounding dialog token field and indicates the presence of the second field via at least two bits. In some embodiments, the first field is a frame control field and indicates the second field via a 4-bit subtype subfield.
