Abstract: Benefits can be obtained by activating or deactivating a Per-Link PM mechanism on behalf of other affiliated non-AP STAs. An affiliated STA may thus activate multiple Per-Link PM mechanisms at once (i.e., using a single notification frame) for multiple affiliated non-AP STAs. A method comprises, at the affiliated non-AP STA, sending one notification frame to an AP MLD to enable or disable power management (PM) on an enabled link between another non-AP STA of the non-AP MLD and the AP MLD, in particular to enable or disable power management (PM) on multiple enabled links with the AP MLD. A Multiple Per-Link PM Mode subfield is provided in the frame to indicate activation or deactivation. A Multiple Per-Link PM Link Bitmap is provided to signal which links are concerned. Finally, a Multiple Per-Link PM subfield indicates the Per-Link PM mechanism to activate, e.g., the Single Link EMLSR feature.
