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.

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.

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.

|
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.

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.

|
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.

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.

8.1.3.1 Description
|
No TX-RX frequency separation is required as Time Division Duplex (TDD) is employed. Each subframe of 1.28 Mcps TDD consists of 7 main timeslots (TS0 ~ TS6) where TS0 (before DL to UL switching point) are always allocated DL, the timeslots (at least the first one) before the switching point (vice versa) are allocated UL and the timeslots after the switching point (vice versa) are allocated DL.

|
The frame structure for 3.84 Mcps TDD and 1.28 Mcps TDD is different. For 3.84 Mcps TDD, each TDMA frame consists of 15 timeslots where each timeslot can be allocated to either transmit or receive.

|
The roll filter factor is would be 0.22, then we select the nominal bandwidth as 1.6MHz.
Considering the easy co-existence with Wide-band TDD mode, for its 3 times bandwidth would be 4.8, less than the nominal bandwidth of wide band UTRA TDD.
It is just nominal for 1.6MHz, and it is also flexible to adjust the channel raster step 200kHz to narrow as 1.4MHz for strict requirement situations if needed.
Considering the easy to implementation, for too narrow band of the bandwidth would be very difficult to implementation.

8.3.2.6 Explanation difference
|
For the 1.28 Mcps chip rate TDD option, one frame(10ms) consists of two subframes(5ms), and one subframe consists of 7 timeslots, the structure of the subframe is shown in section 7.2.1 of TR 25.928. So the number of timeslot i should be 0, 1,…,6. In addition, for the 1.28 Mcps chip rate TDD option, the DL reference measurement channel for 144kbits/s need two timeslots, each consists of 8 DPCH(SF=16).So the number of DPCH in each active TS should be 8.
For the 1.28 Mcps chip rate TDD option, each TS consists of 864 chips, but 16 chips is for Guard Period, so the measuring thermal power should over 848 active chips.

9.3.3.6 Explanation difference
|
For the 1.28 Mcps chip rate TDD option, one frame(10ms) consists of two subframes(5ms), and one subframe consists of 7 timeslots, (the structure of the subframe is shown in section7.2.1 of 3GPP TR 25.928), so the number of timeslot i should be 0, 1,…,6.
The frequency stability is a characteristic of the local oscillator and will not change, if the number of DPCH is varied. In these cases, it is felt that the use of only 1 DPCH will make the measurement easier and, at least for some parameters, more exact. Therefore, it is proposed to specify the test for frequency stability with 1 DPCH only also in the case of 1.28 Mcps TDD option.

8.3.4.2.4.2 Procedure
|
1) Common with 3.84 Mcps chip rate TDD option.
2) Set the BS tester to produce a sequence of TPC commands related to the active DPCH. This sequence shall be transmitted to the BS within the time slots TS i=1,2,3, and shall consist of a series of TPC commands with content "Increase Tx power", followed by a series of TPC commands with content "Decrease Tx power". Each of these series should be sufficiently long so that the transmit output power of the active DPCH is controlled to reach its maximum and its minimum, respectively.
3) Measure the power of the active DPCH over the 848 active chips of each time slot TS i=0,4,5,6 (-this excludes the guard period), and with a measurement filter that has a RRC filter response with a roll off = 0,22 and a bandwidth equal to the chip rate. The power is determined by calculating the RMS value of the signal samples at the measurement filter output taken at the decision points.
