Methods, systems, and devices for wireless communication are described. Some user equipments (UEs) and base stations may communicate in a set of transmission time intervals (TTIs) according to a configured subcarrier spacing (SCS). Each TTI may include, in accordance with the SCS, a quantity of symbols, a corresponding quantity of cyclic prefixes, and a padding duration that may be longer than a symbol duration. The base station may transmit a control signal to the UE to indicate a configuration for the padding duration. The configuration may allocate the padding duration for reference signal repetition or one or more other operations. In some examples, the padding duration may be allocated for beam switching, and the one or more other operations may be different than beam switching. The UE and the base station may perform the reference signal repetition or the other operations during the padding duration based on the configuration.
