7.5 Reference interference level
11.213GPPBase Station System (BSS) equipment specificationRadio aspectsRelease 1999TS
7.5.1 Test Purpose
The reference interference level is a measure of the capability of the receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of an unwanted modulated signal at the same carrier frequency (co-channel interference) or at any adjacent carrier frequencies (adjacent channel interference).
7.5.2 Test Case
If Slow Frequency Hopping (SFH) is supported by the BSS, it shall be disabled during this measurement, except when performing tests using propagation conditions with ideal SFH.
When SFH is used in the test, the BSS shall hop over the maximum range and number of ARFCNs possible for the test environment and which are available in the BSS configuration. If SFH is not supported, the test shall be performed on the specified number of ARFCNs. As a minimum, one time slot shall be tested on one TRX.
Two input signals shall be connected to the receiver via a combining network. When testing each signal shall be connected through a Multipath Fading Simulator (MFS) as described in annex B.1, except in the cases of frequency offsets of the interfering signal from the wanted signal of 400kHz or greater, where the interferer shall be static. The two multipath fading propagation conditions shall be uncorrelated.
The referred power level for both signals shall be the average power into the BSS RX antenna connector. This shall be measured by taking the mean powers of the sum of the individual paths.
For GMSK modulated circuit switched channels, the wanted signal shall have the power level as defined in table 18. It shall have normal GSM modulation. In the case of a pico-BTS, the power level defined in table 18 (*) shall be 4dB greater for measurements performed with interferer offsets of 400kHz or greater.
For packet switched channels and for ECSD, the wanted signal level shall be (X-9dB+Ir), where "X" is the power level defined in table 18 and "Ir" is the co-channel interference ratio defined in table 19b.

DCS1800/PCS 1900/ MXM 1900 pico-BTS P1 | -75 dBm * |
The interfering signal shall be continuous and have GSM modulation of a pseudo‑random bitstream without midamble. If the TRX supports 8-PSK it shall be tested with the interfering signal having GMSK modulation and with the interfering signal having 8-PSK modulation, unless it can be demonstrated that it is sufficient to test either with GMSK or 8-PSK modulated interfering signal. If the TRX does not support 8-PSK it shall be tested with the interfering signal having GMSK modulation. For SFH this interferer shall consist of either one signal which hops in synchronization with the time slot under test or a number of fixed frequency signal sources. In the latter case the number of interfering sources determines the number of frequencies over which the time slot under test can hop in the test environment irrespective of the upper limit of the BTS.
For GMSK modulated circuit switched channels, the test shall be performed with frequency offsets of the interfering signal from the wanted signal, for a relative level of interfering signal above the wanted signal as specified in table 19.
For packet switched channels and ECSD, the test shall be performed with frequency offsets of the interfering signal from the wanted signal, for a carrier to interferer ratio, relative to the co-channel interference ratio (C/Ic), as specified in table 19a. The minimum co-channel interference ratio (C/Ic) for all the combinations of packet switched logical channel type and propagation condition are as specified in table 19b.
In the case of Slow Frequency Hopping (SFH) the interfering signal shall be on the same ARFCN as the wanted signal over the useful part of the time slot burst. For offsets greater than 0 kHz only the multipath propagation condition TU50 (no SFH) need be tested for normal and micro-BTS systems, and only the multipath propagation condition TI5 (no SFH) need be tested for pico-BTS systems.

%NOTE 2: For TU 6 (ideal FH), TU3 (ideal FH) and TU1.5 (ideal FH), sufficient decorrelation cannot readily be achieved between the channel propagation conditions for each frequency hopped on. The requirements in GSM 05.05 (EN 300 910) [22] for performance with TU1.5, TU3 or TU6(ideal FH) propagation condition cannot hence be tested and are thus absent in this test specification. They are inherently tested by TU50 (ideal FH) together with TU3 (no FH), TU 6 (no FH) or TU1.5 (no FH).
NOTE 3: In certain AMR channels, two requirements are given, one at the reference interference ratio and one at 3dB above or below the reference interference ratio. In these cases, only the requirement at 3dB above or below the reference interference ratio needs to be tested, except those marked by an (*), where only the requirement at the reference interference ratio needs to be tested.
