Abstract: A method is provided for performing discovery signal measurements. A user equipment (UE) receives measurement configuration information including a sub-frame offset. The sub-frame offset indicates an offset between a secondary synchronization signal (SSS) and a channel-state information reference signal (CSI-RS) in a discovery signal. The sub-frame offset has a maximum value of four (4). The UE determines a sub-frame for the SSS in the discovery signal, and determines a sub-frame for the CSI-RS based on the sub-frame offset and the sub-frame for the SSS in the discovery signal. The UE performs a measurement on the discovery signal based on the CSI-RS.
