Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a multiple listen-before-talk (LBT) bandwidths, where each LBT bandwidth is associated with one or more downlink control channel candidates of a search space for a control resource set. The UE may monitor the LBT bandwidths during a wakeup signal period for a wakeup signal from the base station. The UE may be configured with a total number of blind hypotheses in the set of blind hypotheses which is equal to or greater than a total number of LBT bandwidths. The UE may determine whether to wake up and monitor an on duration of a discontinuous reception cycle based on detection of the wakeup signal.
