Exploring and configuring the LTE interference management algorithms supported in ns-3

Let’s imagine that an operator purchases a 3 MHz spectrum from the government and decides to use it efficiently. Having a limited spectrum, operators must reuse the same spectrum for all their coverage regions. To do so efficiently, operators usually go for a frequency-reuse 1 deployment. This means an eNB (cell) and its neighboring eNBs (cells) use the same operating spectrum bandwidth (RBs). However, a frequency-reuse 1 deployment (all cells use the same frequency with fixed power – refer to Figure 9.6) leads to high interference from neighboring cells for edge UE (UE at cell boundaries) and edge UE suffers from very poor throughput:

Hence, it is important to manage interference on the network and offer fair throughput results for UE in a cell. In research, a variety...
