8.1 General

All Bit Error Ratio (BER) and Block Error ratio (BLER) measurements shall be carried out according to the general rules for statistical testing defined in ITU-T Recommendation O.153 [5] and Annex C.

If external BLER measurement is not used then the internal BLER calculation shall be used instead. When internal BLER calculation is used, the requirements of the verification test according to 8.6 shall be met in advance.

Performance requirements are specified for a number of test environments and multi-path channel classes.

The requirements only apply to those measurement channels that are supported by the base station. The performance requirements for the high speed train conditions which scenarios defined in Annex D.4A are optional. For FRC8 in Annex 9 and Annex 17 the Non E-DPCCH boosting and E-DPCCH boosting requirement only apply for the option supported by the base station.

Unless stated otherwise, performance requirements apply for a single cell only. Performance requirements for a BS supporting DC-HSUPA or DB-DC-HSUPA are defined in terms of single carrier requirements.

For BS with dual receiver antenna diversity, only the BS performance requirements with Rx diversity are to be tested, the required E_b/N₀shall be applied separately at each antenna port.

For BS without receiver antenna diversity, only the BS performance requirements without Rx diversity are to be tested, the required E_b/N₀shall be applied at the BS Rx antenna port.

In tests performed with signal generators a synchronization signal may be provided, from the base station to the signal generator, to enable correct timing of the wanted signal.

For tests in clause 8 the transmitter may be off.
