English abstract:
LTE Relī 14 is the latest release in which enhance-
ments to Multimedia Broadcast Multicast Services (MBMS) were
introduced. Among the more prominent ones are the newly
defined numerologies that allow for even smaller SubCarrier
Spacing (SCS), the allowance for all resources in a subframe
to be allocated to broadcasting services, dynamically allocate
cells to dedicated broadcast transmission and new Modulation
and Coding Scheme (MCS) values with support for up to 256
Quadrature Amplitude Modulation (QAM) modulation. These
new numerologies define even longer Cyclic Prefixes to help
combat multipath propagation effects with echoes with long
delays, thus allowing for larger inter-cell distances. A natural
consequence is the decrease in resource elements for user
data and thus a decrease in maximum throughput. Another
consideration is the increase in sensitivity towards Doppler
spread with decreasing SCS, giving rise to a trade-off between
user mobility and mitigating multipath echoes. In this paper
we investigate combinations of MCS and SCS under a Single
Frequency Network (SFN) transmission mode across the cell and
towards the border in order to find the most resilient one under
the assumption of user mobility and compare the performance
to a multiple cell scenario with neighboring interferers.
