    Abstract: A multi-link device (MLD) has a medium access control (MAC) layer management entity (MLME) and a station management entity (SME). The SME indicates a selected link identity (ID) to the MLME. The selected link ID is used to indicate the link being used for frame exchange between an access point (AP) affiliated with an AP MLD and a non-AP station (STA) affiliated with a non-AP MLD. One or more frames are exchanged through the link indicated by the selected link ID.

    Abstract: An access point, AP (110), configured to perform a sounding procedure with one or more associated non-AP stations (120) in a wireless local area network (100) is provided. The AP (110) comprises a processing circuitry (111) configured to generate a null data PPDU announcement, NDPA, frame, wherein the NDPA frame comprises for each of the one or more associated non-AP stations (120) a station info field. The station info field comprises a partial BW info subfield, including a feedback bitmap and an indication of a resolution and/or a range of the feedback bitmap with a 20 MHz or 40 MHz subchannel resolution for a Sounding NDP with a bandwidth of up to 320 MHz. The AP (110) further comprises a communication interface (113) configured to transmit the NDPA frame to the one or more associated non-AP stations (120). Moreover, a corresponding non-AP station (120) is disclosed.
