Abstract—The performance of cellular mobile telephone
(LTE) networks is impaired by the amount of interference
experienced within the network. In particular, LTE networks
are susceptible to inter-cell interference which is experienced
when two neighboring cells transmit on the same portion of the
frequency spectrum. We propose an adaptive scheduler that can
be adopted by LTE networks to minimize inter-cell interference;
the scheduler can itself be optimized for the prevailing network
environment by using evolutionary algorithms. We describe this
scheduler along with a number of experiments that explore
its optimization in a number of network environments. In
particular we find that either single-objective or multiobjective
evolutionary algorithms find parameterisations for the adaptive
scheduler that lead to mean throughput for users and sectors
that is comparable to established schedulers, but with signifi-
cantly improved performance for the users at the 5th percentile
of throughput.
