Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a set of reference signal instances within a set of resources. The UE may receive a second indication of a resource element format of a reference signal instance of the set of reference signal instances, the resource element format including one or more null resource elements and one or more reference signal resource elements. The UE may additionally receive, from a base station, a reference signal for estimating carrier frequency offset (CFO) based on the first indication of the set of reference signal instances and the second indication of the resource element format of the reference signal instance. The UE may then communicate with the base station based on receiving the reference signal.
