Abstract
Wake-Up Radio (WUR) has difficulty adapting a wake-up schedule to unpredictable traffic patterns, which inherently cause communication latency. In Smart Scanning, the WUR at the STA side scans for nearby APs for various purposes such as roaming and location measurements. In this paper, we propose to define a WUR Discovery frame to carry the essential information for unassociated STAs to perform smart scanning. However, when an unassociated STA does not know which channel the Discovery frames are transmitted, it needs to scan the entire band which can increase the scan latency significantly before discovering new APs. Therefore, the concept of Discovery Channel(s) is proposed to use when transmitting these WUR Discovery frames.
