Methods, systems, and devices for wireless communications are described that identify a minimum gap between a control channel transmission on a first component carrier (CC) that triggers a measurement report and an associated reference signal transmission on a second CC. The minimum gap may be based on a resource associated with a control channel transmission and a resource associated with the reference signal transmission. The first CC and the second CC have different numerologies and the minimum gap may be identified in terms of a number of OFDM symbols of the second CC that carries the reference signal transmission. The minimum gap also may be identified based on a location of the control channel transmission within a slot of the first CC. In cases where beam switching is used, the minimum gap may be further based at least in part on a beam switch time for performing the beam switching.
