Abstract
A method for allocating utilization of multiple carriers in a wideband CDMA transmission system first determines the carrier utilization/interference levels for each of the multiple carriers. Based on the carrier utilization/interference level, carrier assignments are allocated on an unequal basis. The allocation of the carrier assignment biases the selection of the carriers away from higher utilized/interfered carriers. An apparatus for implementing the method is also described.
