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.
