Abstract:
Scheduler scheme in 4G LTE and its future releases, LTE-A an LTE-A Pro, is a major
parameter which has direct impact on the UE demands (e.g. throughput) and efficiency.
While deploying a new network at a particular site, we have to consider as to what
scheduler needs to be adopted. Transmission mode, on the other hand, indirectly decides
how much UE and also coverage area can be provided by the base stations (eNodeB). An
extensive study of what transmission modes & scheduler are to be chosen for different
sites, has been made in our book. The analysis was carried out by a MATLAB based noncommercial
simulator where a downsized version of the original source was used,
incorporating all the necessary network parameters, to better understand impacts of
changing network parameter in a practical environment. Necessary simulations were carried
out and results were observed. Based on the speculations, we reached some inferences, of
which the most significant would be that, no one transmission mode or scheduler
configuration is the absolute best. It all depends on what goals are to be achieved for a
network at a particular site.
Another work was based on study of NOMA, a transmission technique based on PDMA,
whose main focus is to increase the number of UE per cell, by using the power domain, i.e.
the UE will have different power levels according to their position. Here a general discussion
along with some drawbacks (ICI) and their possible feasible solutions were described in this
book. Since, 5G network aims to provide a higher bandwidth with an increased number of
users, NOMA is one of the feasible choices in terms of transmission techniques over
OFDMA, due to its capability to accommodate higher number of users
