WAKE-UP-RADIO LINK ADAPTATION

The subject of the invention is wake-up-radio link adaptation. An interface circuit in a device, e.g., an access point, may perform link adaptation. During operation, the interface circuit may providea 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 circuitmay 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. 本发明题为"唤醒无线电链路适配"。本发明提供了种设备中的接口电路例如接入点，其可执行
