A method performed by a network node for managing transmission of one or more CRS subframes. The network node identifies if a cell is actively serving a set of UEs. When the cell is actively serving a set of UEs, which set of UEs is configured for DRX the network node sends CRS over the first bandwidth in one or more CRS subframes which are transmitted in the cell during an onDuration interval of the DRX pattern and/or in one or more CRS subframes where system information is sent and/or in one or more CRS subframes where downlink, DL, data is sent. The network node sends CRS over a second bandwidth, in CRS subframes which are not transmitted in the cell during the onDuration interval of the DRX and/or in the one or more CRS subframes except CRS subframes where system information is sent and/or in the one or more CRS subframes except CRS subframes where DL data is sent, which second bandwidth is reduced in relation to the first bandwidth.

Network node and method in a wireless telecommunications network

Method performed by a network node for reducing interference in neighboring cells. The network node operates in a communication network, which is adapted to wirelessly serve a UE via a serving Radio Access, RA, node. The network node obtains a determination of at least one of Reference Signal Received Power, RSRP, and Reference Signal Received Quality, RSRQ, from the serving RA node as received by the UE and a determination of at least one of RSRP and RSRQ from a neighboring RA node as received by the UE, when the UE is connected to the serving RA node. The network node further decides to reduce a transmit power of the serving RA node serving the connected UE, when the determined RSRP and/or RSRQ of the serving RA node is higher than the RSRP and/or RSRQ of the neighboring RA node, in order to reduce the interference in neighboring cells caused by the serving RA node.
