In this course, the main aspects of monitoring the performance of the LTE network and ensuring it is appropriately optimized are covered. Definition of average SINR Probably the most useful performance metric for LTE radio planner is the average signal-to-interference-and-noise ratio, SINRave, defined as SINRave = S I +N, (1) where S is the average received signal power, I is the average interference power, and N is the noise power. Cell-Edge SINR from Simulation, Trial and Real-Life Networks Before a real-life large-scale LTE network is deployed, network performance is estimated via results from system-level simulations and trial networks. In the lower frequency bands and for busy cell sites, a low SINR has an outsized negative impact so SINR optimization is particularly important in these cases. Artificial Intelligence (AI) and Machine Learning (ML) are envisaged to play key roles in 5G networks. Interference rejection combining (IRC) is a method to enhance the capacity in UL by mitigating the undesirable inter‐cell interference.

Base-Station Location Optimization for LTE Systems with Genetic Algorithms. ; RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). ). Another challenge is to coordinate interference and thus enhance the Signal-to-Interference-plus-Noise Ratio (SINR). Analysis and troubleshooting of issues. It should be however noted that 3GPP specifications do not define SINR and therefore UE does not report SINR to the network.
