Claim:
1. A method comprising: receiving, by a user equipment (UE), a set of discovery reference signals (DRS) that include at least one of a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); obtaining configuration information from the DRS about a set of resource elements (REs) in multiple time-domain OFDM symbols, wherein the configuration information indicates whether RE muting has been applied to each of the REs, and wherein RE muting has been applied to a first subset of REs; performing synchronization and cell detection using the first subset of REs in a first subset of OFDM symbols based on the configuration information, wherein the synchronization is performed using the PSS and/or the SSS, and wherein the cell detection is performed using the CRS and/or the CSI-RS; and performing measurement of a first metric using a second subset of REs in a second subset of OFDM symbols based on the configuration information, wherein RE muting has not been applied to the second subset of REs.
