dc.description.abstract
The provision of Quality of Service (QoS) to users
of LTE networks depends to a large degree on the choice of
an appropriate scheduling algorithm able to meet the requirements
of mobile operators. Dynamic packet scheduling has been
recognized as a key approach to maximize the utility of OFDMAbased
systems due to its inherent ability to exploit the frequency
selectiveness of wideband channels both in time and frequency
domain. However, one of the main issues associated to dynamic
scheduling is the high amount of signaling overhead required
to provide users with resource allocation information. While the
impact of control channel limitations on LTE VoIP capacity has
been widely studied yet, tradeoffs associated to control channel
usage and the provision of QoS for Non-Real Time (NRT) services
has been basically omitted in current literature. In this paper,
such tradeoffs have been addressed from several perspectives.
Results show that the relationship between scheduling policies,
offered levels of QoS (expressed in terms of guaranteed bit rates)
and control channels capacity is not trivial and requires careful
planning.
