How to Set the Fractional Power Control Compensation Factor in LTE ?
Abstract
The uplink power control procedure in Long Term
Evolution (LTE) cellular networks is made of an open-loop part
and a closed loop part. In this paper, we focus on the former
and study the compensation factor of the related Fractional
Power Control (FPC) scheme. In particular, we propose a first
analytical approach in order to derive approximate equations
for the Signal to Interference plus Noise Ratio (SINR) at a given
distance of the eNode-B, the average SINR, and the average
cell spectral efficiency. This method avoids extensive and timeconsuming
simulations. From derived expressions, we are able
to find the optimal compensation factor, and to study the impact
of various network and environment parameters on the system
performance.
