Abstract
A new methodology for calculating the spectrum
demand for next generation wireless communication
systems is presented1. The methodology considers a cell or
cell cluster carrying the traffic of a mix of packet based
services, taking the multiplexing gain of packet based traffic
and the service-specific QoS parameters mean throughput,
mean delay and delay percentile into account. A suitable
balance between accuracy and complexity has to be found.
Accordingly, two approaches of different complexity are
presented. A very simple approach maps the expected offered
packet traffic to the required system capacity by
exploiting a characteristic of the relation between system
load and system throughput that is common to all packetbased
systems. A second approach is based on the analysis
of a queuing system. The required system capacity is calculated
for services with mean throughput and mean delay
requirements. Using an additional iterative procedure also
delay percentile requirements can be taken into account.
The queuing approach is more complex but also significantly
more accurate than the simple approach.
