Claim Text:
1. A method in at least one radio network node for handling carrier selection, the method comprising: measuring at least one of interference or load levels on at least two uplink carriers, said measurement being performed in at least one sector of each carrier, wherein the interference or load levels on the at least two uplink carriers are varying in time, wherein random access slots associated with time periods during which the interference or load levels on the at least two uplink carriers are low are announced, and wherein the step of measuring the interference or load levels on at least two uplink carriers is performed during the time periods; calculating an offset based on said measured interference or load levels on the at least two uplink carriers, said offset reflecting the interference or load difference between said at least two uplink carriers; and signaling said offset to a communication device, thereby allowing said communication device to base its carrier selection for random access at least on said measured interference or load levels on said at least two uplink carriers.
