A novel approach for multicell load control in W-CDMA

This paper presents an analytical framework to discriminate the impact that the neighbouring cells have over a reference cell in a multicellular W-CDMA scenario, based on establishing the mutual relationships between cells in terms of uplink cell load factor and downlink transmitted power. The derivatives of these two parameters, with respect to the neighbouring cells, are taken as a measurement of the interactions between cells. Based on this analytical framework, a multicell load control algorithm is proposed and compared with two other algorithms by means of simulations.
