Abstract :
For a regular array of hexagonal cells in a suburban outdoor environment, we examined resource allocation schemes in the radio network controller (RNC) for the uplink and downlink in a UMTS network. In the uplink, the noise rise is the parameter of choice. In the downlink, the power for different data rates and the connection as a whole serves as the means to control the network. Allocating this resource in admission and congestion control, the throughput of a packet service with variable data rate was optimised
