Patent ID: 8515353

Claim:
A method in a first radio base station for decreasing interference of a user equipment present in a first cell towards a second radio base station, wherein the first radio base station and the second radio base station are comprised in a radio communications network and wherein the first radio base station serves the first cell and wherein the second radio base station serves a second cell, the method comprising: receiving data associated with the second radio base station, the data indicating a pathloss between the user equipment and the second radio base station; estimating an uplink interference of the user equipment towards the second radio base station based on the received data; calculating a maximum allowed user equipment transmission power of the user equipment based on a lower bound of the estimated uplink interference of the user equipment; and signalling the maximum allowed user equipment transmission power to the user equipment in the cell, wherein the maximum allowed user equipment transmission power limits a transmission power used by the user equipment.
