Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of sub-bands for receiving, via a set of reconfigurable intelligent surfaces (RISs), a signal. The UE may receive, via a first RIS of the set of RISs, the signal in a first sub-band of the set of sub-bands. The UE may receive, via a second RIS of the set of RISs, the signal in a second sub-band of the set of sub-bands. The UE may transmit, based at least in part on receiving the signal, RIS information indicating at least one of: first RIS information regarding the first RIS, or second RIS information regarding the second RIS. Numerous other aspects are described.
