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 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.
Due to the smaller bandwidth in low chip rate TDD the measurement bandwidth is changed.

8.5.2.1.4.1 Initial conditions
|
Connect the BS tester (UE simulator) generating the wanted signal and a set of interference generators to both BS antenna connectors for diversity reception via a combining network. The set of interference generators comprises a number of CDMA generators, each representing an individual intracell interferer (subsequently called DPCH0 generators) that the DPCH0s are synchronous, and an additional band-limited white noise source, simulating interference from other cells. Each DPCH0 generator shall produce an interfering signal that is equivalent to a valid 1.28 Mcps TDD signal with spreading factor 8, using the same time slot(s) than the wanted signal and applying the same cell-specific scrambling code. The number of the DPCH0 generators used in each test is given in table 8.18.

8.5.2.1.4.2 Procedure
|
1) Adjust the power of the band-limited white noise source in such a way that its power spectral density measured at the BS antenna connector takes on the value Ioc as specified in table 8.18.
2) For a given test defined by the information data rate and the BLER objective, set the power of each DPCH0 measured at the BS antenna connector during the active time slots to the value specified in table 8.20.
3) Set up a call between the BS tester generating the wanted signal and the BS. The characteristics of the call shall be configured according to the information data rate to be provided and the corresponding UL reference measurement channel defined in Annex 8.A. Depending on the information data rate, the UL reference measurement channel makes use of one or two Dedicated Physical Channels (DPCH1 and DPCH2) with different spreading factors SF. The power(s) of DPCH1 and DPCH2 (if applicable) measured at the BS antenna connector during the active time slots shall be set to the value(s) given in table 8.20.
4) Measure the BLER of the wanted signal at the BS receiver.

|
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 subframe is shown in TR 25.928). Considering the chip rate, the burst structure of 1.28 Mcps TDD for normal traffic is different from that of 3.84 Mcps TDD option, (the burst structure for normal traffic is shown in TR 25.928). So the propagation conditions, service mapping and simulation assumption of the measurement channel 12.2kps, 64pks, 144kps and 384kps should be different from those of 3.84 Mcps TDD option. As a result, the relevant parameters should be different.
