This disclosure describes methods, systems, and devices for broadcasting a Physical Downlink Control Channel-based (PDCCH-based) wake-up signal. In one example, a method involves receiving, by one or more user equipment (UEs), a configuration for monitoring a wake up signal (WUS). The method further includes monitoring, by the one or more UEs and based on the configuration, a physical downlink control channel (PDCCH) for downlink control information (DCI) associated with the WUS. The method also includes receiving, by the one or more UEs, the WUS in response to detecting the DCI.
