English abstract:
In order to meet the user requirements in the next
generation radio access technology, the ongoing standardiza-
tion within 3rd Generation Partnership Project (3GPP) offers
flexibility in terms of employing mixed numerology. The term
numerology refers to the parametrization of the multicarrier
modulation scheme. In this paper we consider Single User Single-
Input-Single-Output (SU-SISO) Orthogonal Frequency Division
Multiplexing (OFDM) under the doubly-selective channel. We
investigate the optimal pilot-symbol pattern, accounting not only
for Intercarrier Interference (ICI) and Intersymbol Interference
(ISI) caused by channel conditions, but also considering the
channel estimation error as a consequence of imperfect channel
estimation. As a cost function for our optimization we choose
the upper bound of the constrained capacity and apply it for
different numerology. We show the throughput results in terms
of different numerology and compare it to an LTE-compliant
scenario.
