1  Scope  p. 5

This document is the technical report of the UTRA Tower Mounted Amplifier (FDD) SI which was approved in TSG RAN meeting #28 [1].
The purpose of this TR is to summarize the study of different alternatives how external low noise RX amplifier radio requirements for UTRA FDD could be standardized.
