Techniques for improved wake-up signal (WUS) operation in a wireless communication system are described. In accordance with one embodiment, a wireless communications device may receive, from a gNB, information indicating parameters associated with a wake-up signal time window and may power down its first receiver and second receiver based on a discontinuous reception (DRX) cycle. The wireless communications device may wake up the second receiver to receive, from the gNB, a wake-up signal during a configured WUS time window and determine whether a wake-up or a non-wake-up condition is indicated. If a wake-up condition is indicated, then the wireless communications device may wake up the first receiver before an on duration of the DRX cycle to synchronize timing with the gNB, detect a new radio physical downlink control channel (NR-PDCCH) during the on duration of the DRX cycle, and reset a size of the wake-up signal time window.

An interface circuit in a device, e.g., an access point, may perform link adaptation. During operation, the interface circuit may provide a wake-up frame, e.g., a LP-WUR packet, associated with a channel in a band of frequencies, where the wake-up frame is intended for a wake-up radio in a recipient device. Then, the interface circuit may receive, from the recipient device, feedback information associated with a second channel in a second band of frequencies, where the feedback information is associated with a main radio in the recipient device. Based at least in part on the feedback information, the interface circuit may estimate one or more communication metrics associated with the channel in the band of frequencies. Moreover, based at least in part on the one or more communication metrics, the interface circuit may determine a data rate for use in communication via the channel in the band of frequencies.
