Methods, systems, and devices for wireless communications are described. Some wireless communications systems support user equipment (UEs) achieving power savings by operating in a connected discontinuous reception (C-DRX) mode. The systems may additionally utilize wakeup signals for further power savings at a UE. For example, a UE may be configured with a wakeup signal resource configuration (e.g., a first search space configuration) for monitoring for wakeup signals while operating in a low power mode. This first search space configuration may be different from a second search space configuration for the UE operating in an active mode. When in a low power mode, the UE may monitor for wakeup signals according to the wakeup signal resource configuration. If the UE receives a wakeup signal in a wakeup signal resource defined by the configuration, the UE may initiate a wakeup procedure and transition to the active mode for data transmission and reception.
