The described techniques provide for con- 1-1 O N 00 1-1 ni-slots and a reference signal pattern may be determined based on data payload allocation, modulation coding scheme (MCS), rank, or figuration and transmission of reference signals over aggregated mini-slots by modifying (e.g., extending) transmission time intervals (TTIs) or sharing reference signals across multiple mini-slots. The reference signals may be shared between multiple aggregated mi- other factors of the aggregated mini-slots. Data payloads may be scheduled jointly or separately for each mini-slot and may be allocated across a set of aggregated mini-slots.
