1. An apparatus of a non-access point (AP) station (STA) configured to operate as a first affiliated STA (STA1) of a non-AP multi-link device comprising a plurality of affiliated STAs including the first affiliated station (STA1), a second affiliated station (STA2) and a third affiliated station (STA3), the apparatus comprising: processing circuitry; and memory,
wherein the processing circuitry is configured to:
perform a multi-link setup procedure for multi-link operation with an AP multi-link device comprising a plurality of affiliated APs including a first affiliated AP (AP1), a second affiliated AP (AP2) and a third affiliated AP (AP3), the multi-link setup procedure performed to set up a link between each of the affiliated STAs and a corresponding one of the affiliated APs of the AP multi-link device, the multi-link setup procedure comprising an exchange of an association request frame and an association response frame on a first of the links to set up each of the links including the first link between the first affiliated STA and the first affiliated AP, a second link between the second affiliated STA and the second affiliated AP, and a third link between the third affiliated STA and the third affiliated AP;
wherein each of the links are set up within one of a plurality of bands including a 2.4 GHz band and a 5 GHz band, and
for the first of the links that is enabled for the first affiliated STA for multi-link operation after a successful multi-link setup with the exchange of association request and response frames on the first link, an initial power management mode of the first affiliated STA is set to active mode; and
for the second and the third of the links that are enabled, respectively, for the second and third affiliated STAs for multi-link operation after the successful multi-link setup with the exchange of association request and response frames on the first link, the initial power management mode of the second and third affiliated STAs is set to a power save mode; and
retrieve buffered data from the AP multi-link device over the first link that is enabled for the first affiliated STA (STA1) when the first affiliated STA (STA1) is in the active mode.
