Dynamic power distribution to reference signals in LTE

摘要

The invention is directed to methods and systems for calculating an optimal initial reference signal (RS) power channel estimate utilizing coverage area information and path loss information, where the coverage area is divided into an N number of Terrain Zones (TZs), and where each antenna beam available in a given beam matrix of a given cell, can be mapped to a particular coverage area TZ. Consequently, an optimal initial reference signal or pilot signal power is determined at a power distribution component prior to establishing a link on a per beam and TZ basis, thereby improving QoS. The coverage access components in accordance with the present invention may comprise one or more of a BTS, a femtocell, a picocell, etc.
