Abstract

See full text

The invention relates to an arrangement (900) in a first radio base station (20) for decreasing interference of a user equipment (10) present in a first cell (25) towards a second radio base station (21, 40, 140), which first radio base station (20) and the second radio base station (21, 40, 140) are comprised in a radio communications network and the first radio base station (20) serves the first cell (25) and the second radio base station (21, 40, 140) serves a second cell (26, 42, 142). The arrangement (900) comprises a receiving unit (901) configured to receive data, which data is associated with the second radio base station (21, 40, 140). Furthermore, the arrangement (900) comprises an estimating unit (902) arranged to estimate uplink interference of the user equipment (10) towards the second radio base station (21, 40,140) based on the received data, a calculating unit (903) arranged to calculate a maximum allowed user equipment transmission power of the user equipment (10) from the estimated uplink interference, and a signalling unit (904) configured to signal the maximum allowed user equipment transmission power to the user equipment (10), which maximum allowed user equipment transmission power is arranged to limit a transmission power used by the user equipment (10).
