7.6 Blocking Characteristics

3GPP51.021Base Station System (BSS) equipment specificationRadio aspectsRelease 17TS

7.6.1 Test Purpose

Blocking and spurious response rejection is a measure of the ability of a BSS receiver to receive a wanted GSM modulated signal in the presence of an interfering signal; the level of the interfering signal is higher for the test of blocking than for spurious response.

7.6.2 Test Case

The manufacturer shall declare any intermediate frequencies (IF1 to IFn) used within the receiver, and the frequency of the local oscillator applied to the first receiver mixer.

1) This measurement is carried out in three stages:

a) an optional preliminary test to identify frequencies of interfering signal which require more detailed investigation.

b) measurement of blocking performance:

i) all out-of-band frequencies (general requirements for co-existence)

ii) in case of multicarrier BTS equipped with multicarrier receiver, if the BSS is declared to be suitable for co-location with systems in other frequency bands, in the declared frequency bands (co-location requirements)

c) measurement of spurious response performance; this test need only be performed at those frequencies of interfering signal at which the specification for blocking is not met.

2) The BSS shall be configured to operate as close to the centre of the operating receive band as is possible. In case of multicarrier receiver the BTS configuration in 4.10.10 applies. If Slow frequency hopping is supported by the BSS, it shall be disabled during these measurements.

3) The measurement shall be performed in a test configuration, depending on the declared type of receiver

a) For all types of receivers except multicarrier BTS with multicarrier receiver, the two RF signals shall be fed into the receiver antenna connector of the BSS using a combining network. The wanted signal shall be at the operating frequency of the receiver, shall be modulated with normal GSM modulation, and shall be at a level as specified in table 7.6-1. The measurement is only performed under static propagation conditions.

b) In case of testing Wide Area and Medium Range multicarrier BTS with multicarrier receiver, the maximum supported number of wanted signals or four, whichever is less, and the blocking signal shall be fed into the receiver antenna connector of the BSS using a combining network.

In case of testing Local Area multicarrier BTS with multicarrier receiver, the maximum supported number of wanted signals or two, whichever is less, and the blocking signal shall be fed into the receiver antenna connector of the BSS using a combining network.

The wanted signals shall be equally spread over the maximum Base Station RF bandwidth with two of them allocated at the edge frequencies of the maximum Base Station RF bandwidth of the receiver. Each wanted signal shall use a normal GSM modulation, with a signal level as specified in table 7.6-1 at the receiver input. If no requirement is defined in Table 7.6-3 for a combination of interfering signal power and frequency offset between interferer and wanted signal, the measured data for the corresponding wanted signal(s) may be discarded from the evaluation. The allocation of the center frequency of the RF Base Station bandwidth is set according to 4.10.10 except for out of band blocking tests where it is sufficient to allocate the center of the supported Base Station RF bandwidth as close as possible to the center frequency of the operating band.

The performances of the wanted signals are recorded simultaneously.

The tests are repeated until all applicable interferer levels in table 7.6-3 have been tested.

The measurement is only performed under static propagation conditions without reconfiguring any receiver resources during the test.

If BSS supports both EGPRS and ECSD, it is not necessary to perform testing in both modes. If ECSD channel other than E-TCH/F43.2 NT is to be measured a wanted signal level 3 dB above the test signal level specified in subclause 7.3 shall be used, with the exception for GSM 700, GSM850, MXM850 and MXM 1900 normal BTSs, where a wanted signal 1 dB above the test signal level specified in subclause 7.3 shall be used. If TCH/FS is not supported, the highest supported of PDTCH/MCS-1 to MCS-4 shall be measured using a wanted signal level 3 dB above the test signal level specified in subclause 7.3, with the exception for GSM 700, GSM850, MXM850 and MXM 1900 normal BTSs, where a wanted signal 1 dB above the test signal level specified in subclause 7.3 shall be used. A MXM 1900 normal BTS may instead be tested to the requirements of a PCS 1900 normal BTS.

NOTE 1: f refers to the interfering blocker signal and fo refers to the wanted signal under test. In case of more than one wanted signal under test fo refers to each wanted signal under test as described in step 3b).

NOTE 2: For GSM 400 and GSM 900, for inband requirements for frequency offsets 800 kHz  |f‑fo |, the power level of wanted signal in table 7.6-1 may be increased according to table 7.6-5.

The relaxed values in this Table are not applicable for GSM-R usage.

For GSM 400 and GSM 900, for inband requirements and for frequency offsets |f‑fo | ≥ 3 MHz, the interfering signal level depends on the interferer frequency according to following rule: The higher interfering signal level from the table is used if the interferer frequency is a multiple of 400 kHz and otherwise the lower level.
