A system and method for enhanced cell detection by a User Equipment (UE) is provided. The UE includes a transceiver configured to receive a discovery reference signal (DRS) occasion from at least one transmission point. The DRS occasion comprising a set of consecutive DRS sub-frames. The UE also includes processing circuitry configured to: in response to detecting a physical cell identity (PCID) of a Primary Synchronization Signal (PSS)/ Secondary Synchronization Signal (SSS)/ Common Reference Signal (CRS) that is the same as a reference PCID for a configured Channel State Information Reference Signal (CSI-RS) resource, the processing circuitry attempts to detect or measure the CSI-RS using the timing obtained from the PSS/SSS/CRS; and in response to not detecting a PCID of PSS/SSS/CRS that is the same as the reference PCID for a configured CSI-RS resource (TP), the processing circuitry does not attempt to detect or measure the CSI-RS.
