PROBLEM TO BE SOLVED: To provide techniques for communicating on multiple carriers to mitigate interference in a wireless communication network where different transmit power levels are used for different carriers.SOLUTION: To a first base station is assigned one or more carriers among multiple carriers available for communication. To a second base station is assigned one or more carriers not assigned to the first base station. Each base station may communicate on each assigned carrier at a full transmit power level, and may communicate on each unassigned carrier at a lower transmit power level. The first and second base stations belong in different power classes or support different association types. Control information is sent on a designated carrier to support communication on multiple carriers. In addition, the base stations broadcast bar information indicating the status of carriers. |
