Methods, systems, and devices for wireless communications are described. A network entity may transmit a reference signal to a user equipment (UE). The UE may measure, during a first time period and according to a first periodicity, the reference signal using a first beam associated with cell search. The UE may determine that a movement of the UE satisfies a movement threshold value based on an indication from a motion sensor. Additionally, the UE may determine that a channel metric fails to satisfy a threshold. In response, the UE may measure, during a second time period, the reference signal using the first beam according to a second periodicity that is greater than the first periodicity and corresponds to a more frequent measurement of the reference signal using the first beam than the first periodicity.
