Title: NETWORK NODE AND METHOD FOR MANAGING TRANSMIT POWER
Abstract:
Method performed by a network node (101) for reducing interference in neighboring cells. The network node (101) operates in a communication network (100), which is adapted to wirelessly serve a UE (120) via a serving Radio Access, RA, node (110). 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 (110) as received by the UE (120) and a determination of at least one of RSRP and RSRQ from a neighboring RA node (111) as received by the UE (120), when the UE (120) is connected to the serving RA node (110).The network node (101) further decides to reduce a transmit power of the serving RA node (110) serving the connected UE (120), when the determined RSRP and/or RSRQ of the serving RA node (110) is higher than the RSRP and/or RSRQ of the neighboring RA node (111), in order to reduce the interference in neighboring cells caused by the serving RA node (110).
