1cc4b09fd057c9a5cf925fb9b5a5f4e7 | 25.945 | 6.2.6.1.1 Description | Occupied bandwidth is a measure of the bandwidth containing 99% of the total integrated power for transmitted spectrum and is centered on the assigned channel frequency. 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 | 6.2.6.2.2.1 Frequency offset | Because the nominal bandwidth of 1.28 Mcps TDD option, the spectrum mask definition starts at 0.8MHz offset. |
1cc4b09fd057c9a5cf925fb9b5a5f4e7 | 25.945 | 6.2.6.2.2.2 Measurement bandwidth | “-26dB modulation bandwidth” of 1.28 Mcps TDD option is smaller than that of 3.84 Mcps TDD option, so a higher emission is allowed. 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 t... |

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.

1cc4b09fd057c9a5cf925fb9b5a5f4e7 | 25.945 | 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 U... |
