Abstract
This work proposes a formulation to calculate the
transmitter power needed to cover cells of different sizes whilst
maintaining the average signal to interference-plus-noise ratio
(SINR) constant, and near the maximum, for two long-term
evolution (LTE) systems operating over non-contiguous
frequency bands, 800 MHz and 2 GHz, with an integrated
common radio resource management (iCRRM) entity, in the
context of spectrum aggregation in an LTE-Advanced scenario.
The iCRRM entity is able to switch users between the two LTE
systems. We address a formulation based on the computation of
the average received power and average co-channel interference
in cellular topologies with frequency reuse pattern K=3, keeping
the presence of coverage holes insignificant, whilst considering
the COST-231 Hata path loss model. We have verified how the
normalized power increases as the cell radius increases. The
objective of applying this formulation in the dimensioning
process is to save power for shorter coverage distances.
