Abstract:
1. A method for use in a multi-carrier cellular radio communication system that includes a serving base station currently serving a mobile radio in a serving cell and a non-serving base station within range of the mobile radio and associated with a non-serving cell, where the mobile radio transmits to the serving base station at the same time over multiple radio frequency carriers including a primary frequency carrier in the serving cell and a different secondary frequency carrier in the serving cell and in the non-serving cell, the method comprising: (a) estimating inter-cell interference in the non-serving cell caused by uplink transmission by the mobile radio on the secondary frequency carrier, the uplink transmission being simultaneously transmitted to the serving base station by the mobile station over the primary frequency carrier and the secondary frequency carrier; (b) detecting that the estimated inter-cell interference in the non-serving cell exceeds a predetermined threshold; and (c) reducing or limiting the inter-cell interference in the non-serving cell by managing radio resources so that the estimated inter-cell interference in the non-serving cell is or becomes less than the predetermined threshold.
