Analytical Model for Estimating the Impact of Changing the Nominal Power Parameter in LTE

Abstract EN

UpLink Power Control (ULPC) is a key radio resource management procedure in mobile networks.

In this paper, an analytical model for estimating the impact of increasing the nominal power parameter in the ULPC algorithm for the Physical Uplink Shared CHannel (PUSCH) in Long Term Evolution (LTE) is presented.

The aim of the model is to predict the effect of changing the nominal power parameter in a cell on the interference and Signal-to-Interference-plus-Noise Ratio (SINR) of that cell and its neighbors from network statistics.

Model assessment is carried out by means of a field trial where the nominal power parameter is increased in some cells of a live LTE network.

Results show that the proposed model achieves reasonable estimation accuracy, provided uplink traffic does not change significantly.
