Abstract :
A set of optimisation algorithms are studied for high density wideband code division multiple access (WCDMA) mobile networks. The method to be introduced is a radio resource knapsack packing, as packet traffic is the main consideration. The method includes centralised packet scheduling (PS) and power control (PC) algorithms that will maximise a utility function defined by the operator. The goal of the proposed algorithms is to maximise either the throughput of the system (a cluster of cells) or the value of the correctly received packets
