In this paper, the quality of service in a Long Term
Evolution (LTE) network with respect to the employed scheduling
strategy and the cell-load is investigated. Considering a trafﬁc-
mix with services that have different requirements, the scheduler
needs to be aware of the type of data to be scheduled and
of the state of each user, e.g., the availability of user-data for
transmission or how long a packet of a user has been in the queue
already. Classical schedulers are not designed for such scenarios.
To overcome this situation, we propose two new scheduling
strategies based on proportional fair scheduling since the metric
for proportional fair scheduling is already well suited for the
kind of trafﬁc-mix that we assume in our network. We compare
the performance of the classical scheduling strategies to the new
approaches in terms of average-delay but also throughput by
applying them in trafﬁc-situations, where various services are
used under different load-situations.
