1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
execute an enhanced multi-link single radio operation in a first multi-link device (MLD) device that utilizes a single radio configuration on a set of enabled links that connect the first MLD to an access point (AP) MLD, wherein the enhanced multi-link single radio operation utilizes wake-up receivers to monitor secondary channels for wake-up packets transmitted by the AP MLD;
listen for communications on the set of enabled links;
identify a first communication on a first link of the set of enabled links received from an AP affiliated with the AP MLD, wherein the identification includes detecting a wake-up packet on a secondary channel and switching the primary Wi-Fi radio to the secondary channel; and
perform data frame exchange with the AP MLD based on the identified first communication received from the AP affiliated with the AP MLD, wherein the data frame exchange is performed on the secondary channel identified by the wake-up packet.
