An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR [1]. ACRR BS BW DUT E-TM EARFCN EVM FFS IDFT PB GSM-R RRC TBD TT Adjacent Channel Rejection Ratio Base Station Bandwidth Device Under Test E-UTRA Test Model E-UTRA Absolute Radio Frequency Channel Number Error Vector Magnitude For Further Study Inverse Discrete Fourier Transform Pass Band GSM for Railways Root Raised Cosine To be defined Test Tolerance 4 General test conditions and declarations Many of the tests in this specification measure a parameter relative to a value that is not fully specified in the E- UTRA specifications. For these tests, the Minimum Requirement is determined relative to a nominal value specified by the manufacturer. Some requirements for the Repeater may be regional as listed in subclause 4.2. When specified in a test, the manufacturer shall declare the nominal value of a parameter, or whether an option is supported. 4.1 Measurement uncertainties and test requirements General The requirements of this clause apply to all applicable tests in this specification. The Minimum requirements are given in [2] and test requirements are given in this specification. Test Tolerances are defined in Annex B of this specification. Test Tolerances are individually calculated for each test. The Test Tolerances are used to relax the Minimum requirements in [2] to create Test Requirements Acceptable uncertainty of test system The maximum acceptable uncertainty of the Test System is specified below for each test, where appropriate. The Test System shall enable the stimulus signals in the test case to be adjusted to within the specified tolerance and the equipment under test to be measured with an uncertainty not exceeding the specified values. All tolerances and uncertainties are absolute values, and are valid for a confidence level of 95 %, unless otherwise stated. A confidence level of 95% is the measurement uncertainty tolerance interval for a specific measurement that contains 95% of the performance of a population of test equipment.
12 11 TS V8.3.0 ( ) For RF tests, it should be noted that the uncertainties in subclause apply to the Test System operating into a nominal 50 ohm load and do not include system effects due to mismatch between the DUT and the Test System Measurement of Repeater Table : Maximum test system uncertainty Subclause Maximum Test System Uncertainty and Range over which Test System Uncertainty applies 6 Output power ±0,7 db 7 Frequency stability ±12 Hz Measurement results of ± 500 Hz 8 Out of band gain ±0,5 db Calibration of test set-up shall be made without DUT in order to achieve the accuracy 9.1 Operating band ±1,5 db unwanted emission (except ) The interference from the signal generator ACLR shall be minimum 10 db below that of a Base Protection of the BS receiver in the operating band Station according tots for results > -60 dbm ±2,0 db for results < -60 dbm ±3,0 db 9.2 Spurious emissions In E-UTRA and coexistence receive bands: for results > -60 dbm ±2,0 db for results < -60 dbm ±3,0 db Outside above range: emission power Derivation of Test System Uncertainty 9kHz < f 4 GHz ±2,0 db; f > 4 GHz ±4,0 db.

Formula: RSS 2x Interference signal level error and operating band unwanted emission measurement level error. (1 db interference signal level error is assumed.) 13 Adjacent channel rejection ratio The interference signal must have a spurious emission level at least 10 db below the spurious levels required in 9.2. ±0,7 db
13 12 TS V8.3.0 ( ) Interpretation of measurement results The measurement results returned by the Test System are compared without any modification against the Test Requirements as defined by the Shared Risk principle. The Shared Risk principle is defined in ITU-R M.1545 [3]. The actual measurement uncertainty of the Test System for the measurement of each parameter shall be included in the test report. The recorded value for the Test System uncertainty shall be, for each measurement, equal to or lower than the appropriate figure in subclause of this specification. If the Test System for a test is known to have a measurement uncertainty greater than that specified in subclause 4.1.2, it is still permitted to use this apparatus provided that an adjustment is made as follows. Any additional uncertainty in the Test System over and above that specified in subclause shall be used to tighten the Test Requirement, making the test harder to pass. (For some tests e.g. receiver tests, this may require modification of stimulus signals). This procedure (defined in Annex B) will ensure that a Test System not compliant with subclause does not increase the chance of passing a device under test where that device would otherwise have failed the test if a Test System compliant with subclause had been used.
14 13 TS V8.3.0 ( ) 4.2 Regional requirements Some requirements in the present document may only apply in certain regions.

19 18 TS V8.3.0 ( ) Figure shows the relation between the Channel bandwidth (BW Channel ) and the Transmission bandwidth configuration (N RB ). The channel edges are defined as the lowest and highest frequencies of the carrier separated by the channel bandwidth, i.e. at F C +/- BW Channel / Channel arrangement Channel spacing The spacing between will depend on the deployment scenario, the size of the frequency block available and the channel bandwidths. The nominal channel spacing between two adjacent E-UTRA is defined as following: Nominal Channel spacing = (BW Channel(1) + BW Channel(2) )/2 where BW Channel(1) and BW Channel(2) are the channel bandwidths of the two respective E-UTRA. The channel spacing can be adjusted to optimize performance in a particular deployment scenario Channel raster The channel raster is 100 khz for all bands, which means that the carrier centre frequency must be an integer multiple of 100 khz Carrier frequency and EARFCN The carrier frequency in the uplink and downlink is designated by the E-UTRA Absolute Radio Frequency Channel Number (EARFCN) in the range The relation between EARFCN and the carrier frequency in for the downlink is given by the following equation, where F DL_low and N Offs-DL are given in table and N DL is the downlink EARFCN. F DL = F DL_low + 0.1(N DL N Offs-DL ) The relation between EARFCN and the carrier frequency in for the uplink is given by the following equation where F UL_low and N Offs-UL are given in table and N UL is the uplink EARFCN. F UL = F UL_low + 0.1(N UL N Offs-UL ) Table E-UTRA channel numbers E-UTRA Downlink Uplink operating band F DL_low [] N Offs-DL Range of N DL F UL_low [] N Offs-UL Range of N UL NOTE: The channel numbers that designate carrier frequencies so close to the operating band edges that the carrier extends beyond the operating band edge shall not be used. This implies that the first 7, 15, 25, 50, 75 and 100 channel numbers at the lower operating band edge and the last 6, 14, 24, 49, 74 and 99 channel numbers at the upper operating band edge shall not be used for channel bandwidths of 1.4, 3, 5, 10, 15 and 20 respectively.

Out of band emissions are unwanted emissions immediately outside the pass band bandwidth resulting from the modulation process and non-linearity in the transmitter, but excluding spurious emissions. Spurious emissions are emissions which are caused by unwanted transmitter effects such as harmonics emission, parasitic emission, intermodulation products and frequency conversion products, but exclude out of band emissions. The out-of-band emissions requirement for repeater is specified both in terms operating band unwanted emissions and protection of the BS receiver in the uplink operating band. The Operating band unwanted emissions define all unwanted emissions in the repeater operating band plus the frequency ranges 10 above and 10 below that band. Unwanted emissions outside of this frequency range are limited by a spurious emissions requirement. 9.1 Operating band unwanted emissions Definition and applicability The Operating band unwanted emission limits are defined from 10 below the lowest frequency of the repeater operating band up to 10 above the highest frequency of the repeater operating band. The unwanted emission limits in the part of the operating band that falls in the spurious domain are consistent with ITU-R Recommendation SM.329 [5]. The requirements shall apply whatever the type of repeater considered (one or several pass bands). It applies for all configurations foreseen by the manufacturer"s specification. The requirements of either subclause (Category A limits) or subclause (Category B limits) shall apply. The application of either Category A or Category B limits shall be the same as for spurious emissions (Mandatory Requirements) in subclause For Category B Operating band unwanted emissions, there are two options for the limits that may be applied regionally. Either the limits in subclause or subclause shall be applied Minimum requirements The minimum requirements are in TS [2] sub-clause 9.1.
24 23 TS V8.3.0 ( ) Test purpose This test measures the operating band unwanted emission from the Repeater transmitter antenna connector, while the Repeater is in operation with, and without signal Method of test Initial conditions Test environment: normal; see Annex A2. A measurement system set-up is shown in annex C. 1) Connect a signal generator to the input port of the Repeater. 2) Detection mode: True RMS Procedures 1) Set the Repeater to maximum gain. 2) Set the signal generator to generate signal(s) in accordance to table Table : Stimulus signal for operating band unwanted emissions testing Repeater under test link and passband bandwidth Downlink pass band BW < 2.8 Uplink pass band BW < 2.8 Downlink pass band BW 2.8 Uplink pass band BW 2.8 Stimulus reference Note Repeater stimulus signal 4 The signal is defined in Annex D.4 Repeater stimulus signal 3 The signal is defined in Annex D.3 Repeater stimulus signal 2 The signal is defined in Annex D.2 Repeater stimulus signal 1 The signal is defined in Annex D.1 at centre frequencies such that the whole signal can be fitted inside the repeater pass band and at level(s) which produce the manufacturer specified maximum output power at maximum gain. 3) The detecting device shall be configured with a measurement bandwidth as stated in the test requirement tables. 4) Measure the emission at the specified frequencies with specified measurement bandwidth and note that the measured value does not exceed the specified value. To select the table and the maximum level, use the repeater pass band and stimulus signal if necessary. 5) Increase the input power with 10 db compared to the level obtained in step 2. 6) Measure the emission at the specified frequencies with specified measurement bandwidth and note that the measured value does not exceed the specified value. To select the table and the maximum level, use the repeater pass band and stimulus signal if necessary. 7) If the pass band is wider than 2,8, repeat step 1) to 6) with a new stimulus signal of the same kind, but using different centre frequencies such that the whole signal fitted in the repeater pass band. 8) Switch off the input signal to the repeater. 9) Measure the emission at the specified frequencies with specified measurement bandwidth and note that the measured value does not exceed the specified value. To select the table and the maximum level, use the repeater pass band.
25 24 TS V8.3.0 ( ) NOTE: As a general rule the resolution bandwidth of the measuring equipment should be equal to the measurement bandwidth. However, to improve measurement accuracy, sensitivity and efficiency, the resolution bandwidth may be smaller than the measurement bandwidth. When the resolution bandwidth is smaller than the measurement bandwidth, the result should be integrated over the measurement bandwidth in order to obtain the equivalent noise bandwidth of the measurement bandwidth Test requirements Emissions shall not exceed the maximum levels specified in the tables below, where: - Δf is the separation between the nominal pass band edge frequency and the nominal -3dB point of the measuring filter closest to the carrier frequency. - Nominal passband edge is the lowest and highest frequency of the pass band of the repeater. - BW Meas is the measurement bandwidth. - BW Pass band is the bandwidth of the repeaters pass band. - f_offset is the separation between the nominal pass band edge frequency and the centre of the measuring filter. - f_offset max is the offset to the frequency 10 outside the repeater operating band. - Δf max is equal to f_offset max minus half of the bandwidth of the measuring filter. The requirements of either subclause or subclause shall apply. The Additional operating band unwanted emission limits defined in subclause below may be mandatory in certain regions. In other regions it may not apply. The requirements of subclause shall apply. Unless otherwise stated, all requirements are measured as mean power (RMS) Operating band unwanted emission (Category A) For E-UTRA FDD repeater operating in Bands 5, 6, 8, 12, 13, 14 and 17 emissions shall not exceed the maximum levels specified in Tables and The measurements shall apply to both paths uplink and downlink of the Repeater.
