The UMTS Network and Radio Access Technology Less than -47 dBm/100 kHz at the UE antenna connector, for the frequency band from 1 GHz to 12.75 GHz.

Specifications in [1,2] describe the performance for the transmitter and receiver charac- teristics. UTRA RF PERFORMANCE EXAMPLES In the sequel we provide RF system scenarios based on the studies reported in [5]. Here we aim primarily to illustrate the principles outlined in the preceding sections in order to present practical applications of the recommended parameters. The examples may not strictly apply to actual designs; however, they could serve as reference for initial analy- 5.5.1 Coexistence FDD/FDD: ACIR Before we describe a methodology, we first define some of the essential terminology as in [5] for the context of the examples to follow: Outage - in this context an outage occurs when, due to a limitation on the maximum TX power, the measured Eb/No of a connection is lower than the Eb/No target. Satisfied user - a user is satisfied when the measured Eb/No of a connection at the end of a snapshot, is higher than a value equal to Eb/No target -0.5 dB. ACIR - the Adjacent Channel Interference Power Ratio (ACIR) is defined as the ratio of the total power transmitted from a source (base station or UE) to the total interference power affecting a victim receiver, resulting from both transmitter and receiver imper- fections. 5.5.1.1 Overview of Simulation Assumptions Simulations use snapshots where we
