Talk: IEEE International Conference on Communication Systems, Chengdu, China; 12-19-2018 - 12-21-2018; in: "16th International Conference on Communication Systems", L. Marijanovic, S. Schwarz, M. Rupp (ed.); IEEE, (2018).

We consider a multi-user system that employs mixed
numerology as defined by the 3rd Generation Partnership Project
for a new radio physical layer design. Accounting for different
channel conditions, imperfect channel knowledge and inter-band
interference as a consequence of mixed numerology, we propose
a new optimization method for resource allocation. Based on
this method, we are able to optimally distribute the available
bandwidth amongst the users, such that they achieve the same
quality of service. We show how resource allocation depends on
the channel properties such as Doppler and delay spread. In
addition, optimal resource allocation is verified by simulations of
a 5G compliant system.
