Abstract

Cellular third-generation wideband code division multiple access (WCDMA) systems must meet interference constraints to maintain coverage when uplink traffic is scheduled. The interference constraints can be expressed in the form of load factor constraints but current scheduling algorithms are typically not formulated in terms of these variables. The current paper shows how a cost function for the scheduling problem can be expressed directly in terms of load factors. A near optimal solution is developed for the resulting problem.
