Abstract: Out-of-link channel sounding using an out-of-band channel sounding link for multi-link devices (MLDs) in a wireless network may be provided. An Access Point (AP) may establish a first Wireless Communication Link (WCL) with a Multi-link Device (MLD). The AP may also establish a second WCL with the MLD. After establishing the first WCL, the AP may transmit a sounding trigger to the MLD on the first WCL. After transmission of the sounding trigger to the MLD on the first WCL, AP may transmit a Channel State Information (CSI) inquiry to the MLD on the second WCL. AP may receive a channel state quantification from the MLD on the second WCL in response to the CSI inquiry.
