Abstract

This paper addresses an efficient, low complexity, allocation of channelisation codes for downlink shared channel in the UMTS Third Generation cellular telecoms system. The cumulative code weight is tracked as users are added to the transmission schedule, the required codes are then sorted by spreading factor, and allocated in a simple direct manner.
