1 Overview

Specification 3GPP TS 25.141 FDD R99 [1] describes methods for testing

the transmission parameters (chapter 6) and reception parameters

(chapter 7) of WCDMA base stations. The expressed high flexibility of

UMTS with regard to the provision of different services imposes a

correspondingly high flexibility on the physical layer. Without special

measures, however, this would inflate testing costs enormously. Therefore

to ensure perfect comparability of measurement results and to reduce the

cost of testing, the specification committees have developed the following

test scenarios:

• All transmitter measurements of the downlink (DL) signal must be

carried out using specially designated channel combinations known as

test models. Specification 3GPP FDD R99 details four test models.

• BER measurements for testing the reception channel must be

performed using what is known as a reference measurement channel

(RMC). In this the pseudo random noise (PN) modulated uplink (UL)

signal is started by the transmission time interval (TTI) trigger on the

base station. The bit error ratio (BER) can be evaluated in the Node B,

the RNC or an external BER analyzer. Specification 3GPP FDD R99

details five reference measurement channels (RMC).
