7 7 EN V1.1.1 ( ) 3 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in EN [1], clause 3 and the following apply: Forward CDMA channel: CDMA channel from a base station to mobile stations NOTE: The Forward CDMA Channel contains one or more code channels that are transmitted on a CDMA frequency assignment using a particular pilot PN offset. International Mobile Telecommunications-2000 (IMT-2000): third generation mobile systems which provide access, by means of one or more radio links, to a wide range of telecommunications services supported by the fixed telecommunication networks (e.g. PSTN, ISDN, or IP), and to other services which are specific to mobile users Radio Configuration (RC): set of Forward Traffic Channel and Reverse Traffic Channel transmission formats that are characterized by physical layer parameters such as transmission rates, modulation characteristics, and spreading rate Reverse CDMA Channel: CDMA channel from the mobile station to the base station NOTE: From the base station's perspective, the Reverse CDMA Channel is the sum of all mobile station transmissions on a CDMA frequency assignment. Signal and control port: port which carries information or control signals, except from antenna and telecommunication ports Traffic Channel: communication path between a mobile station and a base station used for user and signalling traffic 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: BS FER PN RC Base Station Frame Error Rate Pseudorandom Number Radio Configuration 4 Test conditions For the purpose of the present document, the test conditions of EN [1], clause 4, shall apply as appropriate. Further product related test conditions for base station equipment are specified in the present document. 4.1 General The equipment shall be tested in normal test environment defined in 3GPP2 C.S0010-A [6]. The test conditions shall be recorded in the test report. For emission and immunity tests, the test arrangements, etc., as specified in the present document, clauses 4.2 to 4.5, shall apply. For an EUT which contains more than one BS, it is sufficient to perform tests relating to connectors of each representative type of port forming part of the EUT. Precautions should be taken to ensure that the cables connecting antenna connectors to test equipment or termination do not influence the test results.
8 8 EN V1.1.1 ( ) 4.2 Arrangements for test signals The provisions of EN [1], clause 4.2 shall apply with the following modifications. The wanted RF signal nominal frequency shall be selected by setting the CDMA channel to an appropriate number. A communication link shall be set up with a suitable mobile station simulator (hereafter called "the test system") according to the Radio Configuration (RC) supported by the base station (see clause 1.3 in 3GPP2 C.S0010-A [6]) using full data rate only. The test system shall be located outside of the test environment. When the EUT is required to be in the transmit/receive mode, the following conditions shall be met: - the transmitter part of the EUT shall be commanded to operate at maximum rated transmit power; NOTE: This may be achieved by disabling the transmitter RF power control. - adequate measures shall be taken to avoid the effect of the immunity test RF signal on the measuring equipment Arrangements for test signals at the input of transmitters The provisions of EN [1], clause shall apply Arrangements for test signals at the output of transmitters The provisions of EN [1], clause shall apply Arrangements for test signals at the input of receivers The provisions of EN [1], clause shall apply with the following modification. For immunity testing the wanted RF signal level at the input of the EUT shall be set to no more than 40 db above the reference sensitivity level as defined in3gpp2 C.S0010-A [6], to provide a stable communications link. The input signal level used in the test shall be noted in the test report. For emission testing the wanted RF signal level at the input of the measuring receiver shall be set to no more than 15 db above the reference sensitivity level as defined in3gpp2 C.S0010-A [6], to ensure that it operates within its dynamic range. The input signal level used in the test shall be noted in the test report Arrangements for test signals at the output of receivers The provisions of EN [1], clause shall apply. 4.3 Exclusion bands For radio equipment in the scope of the present document the exclusion band does not apply. 4.4 Narrow band responses of receivers Responses on receivers or duplex transceivers occurring during the immunity test at discrete frequencies which are narrow band responses (spurious responses), are identified by the following method: - if during an immunity test the quantity being monitored goes outside the specified tolerances (see clause 6.1), it is necessary to establish whether the deviation is due to a narrow band response or to a wideband (EMC) phenomenon. Therefore, the test shall be repeated with the unwanted signal frequency increased, and then decreased by 10 MHz; - if the deviation disappears in either or both of the above 10 MHz offset cases, then the response is considered as a narrow band response;
9 9 EN V1.1.1 ( ) - if the deviation does not disappear, this may be due to the fact that the offset has made the frequency of the unwanted signal correspond to the frequency of another narrow band response. Under these circumstances the procedure is repeated with the increase and decrease of the frequency of the unwanted signal set to 12,5 MHz; - if the deviation still does not disappear with the increased and/or decreased frequency, the phenomenon is considered wideband and therefore an EMC problem and the equipment fails the test. For immunity tests, narrow band responses shall be disregarded. 4.5 Normal test modulation A communication link shall be set up with a suitable base station system test equipment. The normal test modulation should be setup according to the Radio Configuration (RC) supported by the base station under test using full data rate only (see clause 1.3 in 3GPP2 C.S0010-A [6]). 5 Performance assessment 5.1 General The provision of EN [1], clause 5.1 shall apply with the following modification. The information about the bandwidth of the IF filter immediately preceding the demodulator as set out in EN [1], clause 5.1 is not applicable to radio equipment in the scope of the present document. 5.2 Equipment which can provide a continuous communication link The provision of EN [1], clause 5.2 shall apply Assessment of FER in Forward Link (Downlink) For immunity testing, the output of the transmitter shall be connected to a test system which meets the requirements for the FER assessment in accordance with 3GPP2 C.S0002-A [5] and 3GPP2 C.S0010-A [6]. The power control of the transmitter shall be disabled. The level of the signal supplied to the test system shall be attenuated such that it is within the range for which the assessment of FER is not impaired Assessment of FER in Reverse Link (Uplink) The value of the FER at the output of the receiver reported by the BS shall be monitored using a suitable test system. 5.3 Equipment which does not provide a continuous communication link The provision of EN [1], clause 5.3 shall apply. 5.4 Ancillary equipment The provision of EN [1], clause 5.4 shall apply. 5.5 Equipment classification The provision of EN [1], clause 5.5 shall apply.
10 10 EN V1.1.1 ( ) 6 Performance criteria 6.1 Performance criteria for continuous phenomena applied to Base Stations (BS) During the immunity test, the observed Frame Error Rate (FER) of the BS forward link and reverse link shall not exceed 1,0 % with 95 % confidence (see clause 6.8 in 3GPP2 C.S0010-A [6]), and the BS shall operate as intended. After each test case, the BS shall operate as intended with no loss of user control function, or stored data, the communication link shall be maintained. 6.2 Performance criteria for transient phenomena for Base Stations (BS) During each individual exposure in the test sequence, the observed Frame Error Rate (FER) of the BS forward link and reverse link may temporarily exceed 1,0 % with 95 % confidence. After each test case, the BS shall operate as intended with no loss of user control function, or stored data, the communication link shall be maintained. 6.3 Performance criteria for ancillary equipment tested on a stand alone basis The provision of EN [1], clause 6.4 shall apply. In addition, the provisions of clauses and of the present document shall apply Performance criteria for continuous phenomena for ancillary equipment The EUT shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed below the performance level specified by the manufacturer, when the apparatus is used as intended. The performance level may be replaced by a permissible performance loss. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended Performance criteria for transient phenomena for ancillary equipment The EUT shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below the performance level specified by the manufacturer, when the apparatus is used as intended. The performance level may be replaced by a permissible performance loss. During the test, degradation of performance is however allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended.
