Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first reference signal (RS) from a first antenna panel of a plurality of antenna panels associated with at least one transmit receive point (TRP) of a scalable cell system that includes a set of anchor TRPs associated with a cell and a set of on-demand TRPs associated with the cell, wherein the first RS is associated with a frequency and a transmission configuration indicator (TCI). The UE may receive a second RS from a second antenna panel of the plurality of antenna panels, wherein the second RS is associated with the frequency and the TCI, and wherein the at least one TRP comprises an on-demand TRP. Numerous other aspects are described.
