1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.5.1.2 Rationale	Assuming the Noise Figure(NF) of BS is 7dB and Minimum Couple Loss(MCL) is 30dB. For the victim receiver, the Tx OFF power should not exceed the thermal noise. If Tx OFF power is 6dB below thermal noise, it will introduce 1dB degradation. The proposal for Tx OFF power is as follows: NOTE: In 1.28 Mcps TDD option, The noise figure of BS is assumed to be 7dB, it is based on that this parameter has been approved by CWTS yet and it is easier for implementation of BS.

The occupied channel bandwidth is about 1.6 MHz based on a chip rate of 1.28 Mcps.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.6.1.2 Explanation of difference	In 3.84 Mcps TDD, the occupied channel bandwidth is less than 5MHz based on 3.84 Mcps. But in 1.28 Mcps TDD, as the background analysis in WG4#12 Meeting Tdoc515, which has been accepted to into the TR25.945, the occupied channel bandwidth should be less than 1.6 MHz based on 1.28 Mcps.

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.6.2.2 Explanation
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.6.2.2.1 Frequency offset	Because the nominal bandwidth of 1.28 Mcps TDD option, the spectrum mask definition starts at 0.8MHz offset.

However, in accordance with the 3.84 Mcps TDD option, the same level and measurement bandwidth are used.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.6.2.2.3 Mask shape	For the flat region from 0.8MHz to 1.0MHz, it gives sufficient margin to cope with the unwanted spectral response due to baseband modulation, and allows to provide additional protection for the second narrow-band channel in case of narrow-band services (using 200kHz channel raster). In addition, the slope from 1.0MHz to 1.8MHz is for reflecting more accurately PA behaviour and providing further guarantee on levels in adjacent bandwidth. 6.2.6.2A Adjacent Channel Leakage power Ratio(ACLR) 6.2.6.2A.1 Minimum requirement For the 1.28 Mcps chip rate option, the ACLR shall be better than the value specified in the following Table.

If the actual allowed interference level Pint, allowed, actual at the victim receiver is higher than –106dBm, this requirement may be relaxed by the amount Pint, allowed, actual – (-106dBm). 6.2.6.2A.3 Requirement in case of co-siting with TDD BS or FDD BS operating on an adjacent frequency In case the equipment is co-sited to another TDD BS or FDD BS and both BSs operating on an adjacent frequency band, the requirement is specified in terms of power level of the transmitting BS. This requirement is valid for co-existence with a non-frame and non-switching point synchronised systems operating on closest used carrier. The interference power level shall not exceed the limit in Table 6.7.

If the actual MCLactual is higher than 30dB, this requirement may be relaxed by the amount MCLactual – 30dB. If the actual allowed interference level Pint, allowed, actual at the victim receiver is higher than –106dBm, this requirement may be relaxed by the amount Pint, allowed, actual – (-106dBm).

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.6.3.1.0 Explanation of difference	In 3.84 Mcps option, the frequency offset from carrier frequency is greater than 12.5MHz, while in 1.28 Mcps option it is greater than 4 MHz. In ITU specification, the frequency limit between out of band emissions and spurious emissions is defined as 250% of the necessary bandwidth. In 1.28 Mcps option the necessary bandwidth is 1.6MHz, so the frequency offset from carrier frequency is:

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.7 Transmit intermodulation	The transmit intermodulation performance is a measure of the capability of the transmitter to inhibit the generation of signals in its non linear elements caused by presence of the wanted signal and an interfering signal reaching the transmitter via the antenna. The transmit intermodulation level is the power of the intermodulation products when a CDMA modulated interference signal is injected into the antenna connector at a level of 30 dB lower than that of the subject signal. The frequency of the interference signal shall be 1.6 MHz, 3.2 MHz and 4.8 MHz offset from the subject signal.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.7.0 Explanation of difference	In 1.28 Mcps option, the necessary bandwidth is 1.6MHz. The frequency of interference signal is 1NB,2NB and 3*NB offset from the subject, that means 1.6 MHz, 3.2 MHz and 4.8 MHz. In 3.84 Mcps option, the necessary bandwidth is 5 MHz.

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.8.1.1 Explanation of difference	The chip rate for 1.28 Mcps TDD option is 1.28 Mcps, the chip duration is . While in 3.84 Mcps TDD option, the chip rate is 3.84 Mcps, the duration is .
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.8.2 Modulation Accuracy	Common with 3.84 Mcps TDD option.

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.8.3.1 Minimum Requirement	Common with 3.84 Mcps TDD option.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.2.8.3.2 Rationale	For 3.84 Mcps TDD and FDD, the minimum requirements for the error vector magnitude and peak code domain error ensures that - the error vector magnitude does not degrade the performance - the error vector magnitude leads only to low increase for the transmitted output power to remain the Eb/N0 The theoretical investigations have shown that the error vector magnitude is related to the spreading factor. Because the same spreading factors are used for 1.28 Mcps TDD and for 3.84 Mcps TDD, the same minimum requirement applies.

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.1 General	Common with 3.84 Mcps TDD option.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.2 Reference sensitivity level	The reference sensitivity is the minimum receiver input power measured at the antenna connector at which the FER/BER does not exceed the specific value indicated in section 6.3.2.1.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.2.1 Minimum Requirement	For the measurement channel specified in the Annex C, the reference sensitivity level and performance of the BS shall be as specified in table 6.9 below. Table 6.9: BS reference sensitivity levels Data rate BS reference sensitivity level (dBm) FER/BER 12.2 kbps -110 dBm BER shall not exceed 0.001
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.2.2 Rationale	The reference sensitivity value of BS for 1.28 Mcps TDD is derived from the following formula. Assuming the noise figure(NF) of BS is 7dB, the noise floor is: According to the simulation results for 12.2Kbps measurement channel, the BER=0.001 is achieved at Îor/Ioc = 1.2dB with an own code power of 1/5 of the whole transmit code power (-7dB). In simulation, assume Îor equal to Ior, we can get: The sensitivity value without implementation is calculated as follows: If the implementation margin is considered to be 1.5dB, the final sensitivity value is: The reference sensitivity value of –110dBm is proposed to the BS specification for 1.28 Mcps TDD . NOTE: In 1.28 Mcps TDD option, The noise figure of BS is assumed to be 7dB, it is based on that this parameter has been approved by CWTS yet and it is easier for implementation of BS.

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.3.2 Rationale	When wanted signal level is 30 dB above the reference sensitivity level, in order to keep the performance of BER0.001 the maximum interfering signal PI needs meet the following requirement: It is also proposed to the BS conformance test, the section 8.4.3 this report. NOTE: In 1.28 Mcps TDD option, The noise figure of BS is assumed to be 7dB, it is based on that this parameter has been approved by CWTS yet and it is easier for implementation of BS.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.4 Adjacent Channel Selectivity (ACS)	Adjacent channel selectivity (ACS) is a measure of the receiver ability to receive a wanted signal at its assigned channel frequency in the presence of an adjacent channel signal at a given frequency offset from the center frequency of the assigned channel.ACS is the ratio of the receiver filter attenuation on the assigned channel frequency to the receive filter attenuation on the adjacent channel(s).
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.4.1 Minimum Requirement	The BER shall not exceed 0.001 for the parameters specified in table 6.12. Table 6.12: Adjacent channel selectivity Parameter Level Unit Data rate 12.2 kbps Wanted signal Reference sensitivity level + 6dB dBm Interfering signal –55 dBm Fuw (Modulated) 1.6 MHz
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.4.2 Rationale	Assuming the receiver filter ACS equals to 45 dBc, in order to keep the performance of BER, the interference signal level PI should meet the following requirement: NOTE: In 1.28 Mcps TDD option, The noise figure of BS is assumed to be 7dB, it is based on that this parameter has been approved by CWTS yet and it is easier for implementation of BS.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.5 Blocking characteristics	The blocking characteristics is a measure of the receiver ability to receive a wanted signal at its assigned channel frequency in the presence of an unwanted interferer on frequencies other than those of the adjacent channels. The blocking performance shall apply at all frequencies as specified in the tables below, using a 1MHz step size.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.5.1 Minimum Requirements	For the 1.28 Mcps chip rate option, the requirement of Blocking for carrier spacing 1.6MHz is prescribed in the following tables. Table 6.13: Blocking requirements for operating bands defined in 6.1.2(a) Center Frequency of Interfering Signal Interfering Signal Level Wanted Signal Level Minimum Offset of Interfering Signal Type of Interfering Signal 1900 – 1920 MHz, 2010 – 2025 MHz -40 dBm <REFSENS> + 6 dB 3.2MHz Narrow band CDMA signal with one code 1880 – 1900 MHz, 1990 – 2010 MHz, 2025 – 2045 MHz -40 dBm <REFSENS> + 6 dB 3.2MHz Narrow band CDMA signal with one code 1920 – 1980 MHz -40 dBm <REFSENS> + 6 dB 3.2MHz Narrow band CDMA signal with one code 1 – 1880 MHz, 1980 – 1990 MHz, 2045 – 12750 MHz -15 dBm <REFSENS> + 6 dB  CW carrier Table6.14: Blocking requirements for operating bands defined in 6.1.2(b) Center Frequency of Interfering Signal Interfering Signal Level Wanted Signal Level Minimum Offset of Interfering Signal Type of Interfering Signal 1850 – 1990 MHz -40 dBm <REFSENS> + 6 dB 3.2MHz Narrow band CDMA signal with one code 1830 – 1850 MHz, 1990 – 2010 MHz -40 dBm <REFSENS> + 6 dB 3.2MHz Narrow band CDMA signal with one code 1 – 1830 MHz, 2010 – 12750 MHz -15 dBm <REFSENS> + 6 dB  CW carrier Table 6.15: Blocking requirements for operating bands defined in 6.1.2(c) Center Frequency of Interfering Signal Interfering Signal Level Wanted Signal Level Minimum Offset of Interfering Signal Type of Interfering Signal 1910 – 1930 MHz -40 dBm <REFSENS> + 6 dB 3.2MHz Narrow band CDMA signal with one code 1890 – 1910 MHz, 1930 – 1950 MHz -40 dBm <REFSENS> + 6 dB 3.2MHz Narrow band CDMA signal with one code 1 – 1890 MHz, 1950 – 12750 MHz -15 dBm <REFSENS> + 6 dB  CW carrier
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.6 Intermodulation characteristics	Third and higher order mixing of the two interfering RF signals can produce an interfering signal in the band of the desired channel. Intermodulation response rejection is a measure of the capability of the receiver to receiver a wanted signal on its assigned channel frequency in the presence of two or more interfering signals which have a specific frequency relationship to the wanted signal. The static reference performance as specified in clause 6.3.2.1 should be met when the following signals are coupled to BS antenna input. A wanted signal at the assigned channel frequency, 6 dB above the static reference level. Two interfering signals with the following parameters. Table 6.16: Intermodulation requirement (1.28 Mcps chiprate) Interfering Signal Level Offset Type of Interfering Signal - 48 dBm 3.2 MHz CW signal - 48 dBm 6.4 MHz Narrow band CDMA signal with one code
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.6.1 Rationale	Intermodulation characteristics mean the BS receiver needs to have a sufficient capability to reject the interfering signals. Same frequency bands is applied for 1.28 Mcps and 3.84 Mcps TDD, therefore 1.28 Mcps TDD should be resistant to the same level of interfering signals at other frequencies. The level –48dBm is proposed for interfering signals without brackets.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.7 Spurious emissions	The spurious emissions power is the power of emissions generated or amplified in a receiver that appear at the BS antenna connector. The requirements apply to all BS with separate RX and TX antenna port. The test shall be performed when both TX and RX are on with the TX port terminated. For all BS with common RX and TX antenna port the transmitter spurious emission as specified in section 6.2.6.3 is valid.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.7.1 Minimum Requirement	The power of any spurious emission shall not exceed: Table 6.17: Receiver spurious emission requirements Band Maximum level Measurement Bandwidth Note 9 kHz – 1 GHz -57 dBm 100 kHz 1 GHz – 1.9 GHz and 1.98 GHz – 2.01 GHz -47 dBm 1 MHz With the exception of frequencies between 4MHz below the first carrier frequency and 4MHz above the last carrier frequency used by the BS. 1.9 GHz – 1.98 GHz and 2.01 GHz – 2.025 GHz -83 dBm 1.28 MHz With the exception of frequencies between 4MHz below the first carrier frequency and 4MHz above the last carrier frequency used by the BS. 2.025 GHz – 12.75 GHz -47 dBm 1 MHz With the exception of frequencies between 4MHz below the first carrier frequency and 4MHz above the last carrier frequency used by the BS.
1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	6.3.7.2 Rationale	Assuming the Minimum Couple Loss (MCL) is 30dB. For the victim receiver, the spurious emissions power generated by the BS receiver should not exceed the thermal noise. . The proposal for spurious emission power that located in the 1.9 GHz – 1.98 GHz and 2.01 GHz – 2.025 GHz band is as follows: This leads to the same requirement as for 3.84 Mcps TDD. The different value is only due to the 1.28 MHz measurement bandwidth.

1cc4b09fd057c9a5cf925fb9b5a5f4e7	25.945	7.1.3 Narrow band responses on receivers	For 1.28 Mcps chip rate TDD option, responses on receivers or duplex transceivers occurring during the 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, it is necessary to establish whether the deviation is due to a narrow band response or to a wide band (EMC) phenomenon. Therefore, the test shall be repeated with the unwanted signal frequency increased, and then decreased by 3.2MHz; - if the deviation disappears in either or both of the above 3.2 MHz offset cases, then the response is considered as a narrow band response; - 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 4MHz; - if the deviation does not disappear with the increased and/or decreased frequency, the phenomenon is considered wide band and therefore an EMC problem and the equipment fails the test. Narrow band responses are disregarded.
