Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a first slot format indicator (SFI) during a first monitoring period for a set of slots associated with the first monitoring period. The base station may transmit, and the UE may receive a second SFI during a second monitoring period that is shorter in duration than the first monitoring period and occurs within the first monitoring period, the second SFI comprising an indication of slot formats for a subset of the slots associated with the second monitoring period. The base station and the UE may perform wireless communications over the subset of slots based at least in part on the first SFI and the second SFI.
