The actual interference ratio is defined as the interference ratio for which this performance is met. The actual interference ratio shall be less than a specified limit, called the reference interference ratio. The reference interference ratio shall be, for all types of BTS and all types of MS:

6.3.5 Additional reference interference performance requirements and conditions
If not stated differently, all reference interference specifications in section 6.3 apply only for a random, continuous, GMSK modulated interfering signal.
In case of frequency hopping, the interference and the wanted signals shall have the same frequency hopping sequence. Unless otherwise stated, the wanted and interfering signals shall be subject to the same propagation profiles (see annex C), independent on the two channels.
In case of EC-channels for which dedicated performance requirements are specified, i.e. which do not reuse EGPRS performance requirements, the interferer shall be subject to independent propagation in each burst with each burst generated with random, continuous, GMSK modulated interference.
NOTE: For the purpose of lowering testing complexity for EC-channels, the interferer’s independent propagation condition between bursts can be approximated with a RA250noFH propagation condition for E-GSM900 and GSM850 or RA130noFH propagation condition for DCS 1800 or PCS 1900.
For a GSM 400 MS, a GSM 900 MS, a ER-GSM 900, a GSM 850 MS, a GSM 700 MS, a DCS 1 800 MS and a PCS 1 900 MS the reference interference performance according to table 2 and 2j for co‑channel interference (C/Ic) shall be maintained for RA500/250/130 propagation conditions if the time of arrival of the wanted signal is periodically alternated by steps of 8µs in either direction. The period shall be 32 seconds (16 seconds with the early and 16 seconds with the late time of arrival alternately).
For pico-BTS and Local Area multicarrier BTS, propagation conditions other than static and T15 are not specified and only the no FH case need be tested. The performance requirement for GSM 900, ER-GSM 900, GSM 850, GSM 700, DCS 1 800, PCS 1900, MXM 850 and MXM 1900 pico-BTS and Local Area multicarrier BTS with TI5 propagation condition is the same as theTU50 no FH (900MHz) performance requirement. The interference ratio at which this requirement shall be met is, for GMSK modulated wanted signals, 4dB above the interference ratio specified above in this sub-clause (in combination with Table 2a for packet service). For 8-PSK modulated wanted signals, the interference ratio for this requirement is 4 dB above the interference ratio specified above in this sub-clause (in combination with Table 2b and 2d for packet service). For 16-QAM, 32-QAM and QPSK modulated wanted signals, the interference ratio for this requirement is 4 dB above the interference ratio specified above in this sub-clause (in combination with Table 2r and 2t (16-QAM), and Table 2t (32-QAM and QPSK) for packet service). For Local Area multicarrier BTS and speech channels in VAMOS Mode and their associated control channels, the interference ratio for this requirement is 6 dB above the interference ratio specified above in this sub-clause 6.3 (in combination with Table 2ac). For adjacent channel interference propagation conditions other than TU50 need not be tested. There is an exception in the case of the pico-BTS and Local Area multicarrier BTS in that the specified propagation condition is TI5 instead of TU50; the respective test for pico-BTS and Local Area multicarrier BTS is described in the paragraph following table 6.3-3 below.
If, in order to ease measurement, a TU50 (no FH) faded wanted signal, and a static adjacent channel interferer are used, the reference interference performance shall be:

For pico-BTS and Local Area multicarrier BTS, adjacent channel and cochannel interference propagation conditions other than TI5 need not be tested. If, in order to ease adjacent channel measurements, a TI5 (no FH) faded wanted signal, and a static adjacent channel interferer are used, the interference performance shall be the same as that specified above for a TU50 no FH channel (900MHz). The interference ratio at which this performance shall be met is 4dB above the reference interference ratio specified above in this sub-clause.
In addition, MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008) shall fulfil the requirements in table 2o for wanted signals on GMSK modulated channels under TU50 no FH propagation conditions and GMSK modulated interferers for the test scenarios defined in annex L, unless when the MS is assigned a Downlink Dual Carrier configuration (see 3GPP TS 44.060) comprising a total of more than 8 timeslots, in which case, the MS shall only fulfil the requirements at least on all the timeslots that are assigned on the carrier 1 (see 3GPP TS 44.060).

For equipment supporting 8-PSK, and for MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008), the applicable TIGHTER requirements in table 2ad for TCH/WFSx and PDTCH, and table 2af for TCH/WFSx, PDTCH/CSx, PDTCH/MCSx and PDTCH/DASx apply for both GMSK and 8-PSK modulated interfering signals.
The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition to table 6.3-6, for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2ad, 2ae and 2af at the corresponding interference ratio C/Ic, C/I1, and C/Ia1, respectively.
