Methods, systems, and devices for wireless communications are described in which a network entity may use a lower power sleep procedure to reduce power consumption, and monitor for a wake-up signal (WUS) from at least one user equipment (UE) during configured WUS occasions. The WUS from one or more UEs may provide information of one or more attributes of data traffic that is present at a transmit buffer of the one or more UEs. A WUS configuration may be provided from a network entity that allows the selection of a particular WUS to indicate one or more attributes of the data traffic at the UE. The WUS may convey information such as buffer status, power headroom, a priority of traffic, latency targets of the traffic, or any combinations thereof. The WUS may also give an indication of a requested duration of an active mode at the network entity.
