Patent ID: 10694474

Abstract:
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.
