Abstract
A system for controlling congestion in a code division multiple access system with multi-user detection capabilities is disclosed. The system includes at least one user equipment, a base station, and a radio network controller. Each user equipment includes a receiver having multi-user detection capabilities. The base station includes a receiver having multi-user detection capabilities, an intra-cell interference measuring device, and an inter-cell interference measuring device. The radio network controller includes a radio resource management device configured to control congestion based on measurements taken by the base station.
