    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a measurement configuration that includes information associated with one or more target frequencies in a first frequency range, such as Frequency Range 2 (FR2). The UE may perform measurements of the one or more target frequencies in the first frequency range in accordance with the measurement configuration while the UE is in an idle or inactive state. The UE may transition from the idle or inactive state to a connected state based on performing a random access procedure with a network entity. Accordingly, the UE may transmit an indication of a measurement report associated with the measurements of the one or more target frequencies in the first frequency range based on transitioning from the idle or inactive state to the connected state.
