The base station may determine a bandwidth for transmitting the CRS to a user equipment, wherein the bandwidth is less than a system bandwidth and may transmit the CRS to the UE using the determined bandwidth, wherein the UE monitors for the CRS on a set of monitored RBs. The set of monitored RBs may include RBs allocated for a PDCCH search space, PDCCH and/or PDSCH trans- missions and may further include RBs M subframes after and/or N sub- frames before the monitored RBs. The set of monitored RBs may include X RBs around a PDCCH search space and/or PDSCH.
