Methods and Arrangements for Handling Carrier Selection

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;
• 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.

A radio network arrangement configured for handling carrier selection and comprising:

• a receiver and an associated measurement processor configured to measure interference or load levels on at least two uplink carriers, said measurement being performed in at least one sector of each carrier;
• a calculation processor configured to calculate an offset based on the 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
• a transmitter and an associated signaling processor configured to signal said offset to a communication device, thereby allowing said communication device to base its carrier selection for random access at least on the interference or load levels on said at least two uplink carriers.
