Abstract
A method performed by a network node for managing transmission of Cell Reference Symbols, CRS, wherein the network nodeoperates one or more cells and the network nodeis configured to transmit the CRS in a first bandwidthmode. When the network nodehas identified a cellwhich is not actively serving any UEs, also referred to as an empty cell, the network nodeapplies() a reduced CRS bandwidth mode in the first cellin relation to the first bandwidthmode. By applying () a reduced CRS bandwidth mode in the empty cell, the overall interference of the CRS from the empty cellis reduced, thereby enhancing the performance in cells actively serving UEs
