14.18.9.1.4 Test method

14.18.9.1.4.1 Initial condition

The SS is configured as defined in annex N.2 picture N.2.2 of 3GPP 45.005

The diversity parameter for the antenna correlation is set to 0 and the antenna gain imbalance (AGI) is set to 0 dB

A call is set up according to the generic call set up procedure with an ARFCN in the mid ARFCN range on the maximum number of receive timeslots which the MS is capable to support. The power control level set to maximum power.

d) The SS sets the level of the wanted signal 1dB above the value according the Table 14.18.9.1.5-1 and Table 14.18.9.1.5-2.

e) The SS transmits the number of blocks with current coding scheme accordingly with table 14.16-2 and counts the BLER based on the content of the ACK/NACK Description information element (see 3GPP TS 04.60, sub clause 12.3) in the Packet Downlink ACK/NACK as sent from the MS to the SS on the PACCH. The SS resets both counters.
