    Abstract: A base station selects, in response to a location request for a UE, RIS(s) to use for positioning purposes for the UE. The base station performs a process with the selected RISs to determine information used to configure the UE with RS configuration for using the selected RIS(s) for the positioning purposes. The base station sends the RS configuration to the UE. An RIS receives signals including RSs to be used for positioning purposes for a UE. The RIS time stamps the signals with the RSs and reflects signals including the RSs and corresponding time stamps. A UE receives a reference signal configuration for using RIS(s), receives RSs based on the configuration, and receives signals comprising RSs that have been reflected from the RIS(s). The UE performs timing estimates based on the received signals and sends indication of the timing estimates toward the base station.
