TX burst mode is enabled when <param10> is set to 1. The mode
allows non-continuous TX transmission. The ON and OFF periods are based on the reference
measurement channel uplink subframe scheduling that is defined for LTE-M in 3GPP TS 36.521
Annex A, Section A.2.2 and for NB-IoT in 3GPP TS 36.521 Annex A, Section
A.2.4. The burst signal is transmitted until the TX OFF command is
given.v1.2.1pti_v1.1.x≥1
The following table describes the different waveforms supported by <param3>, <param4>, <param5>, and <param7>:
| System mode <param3> | Modulation <param4> | RB/Tone count <param5> | Subcarrier spacing <param7> |
|---|---|---|---|
| NB-IoT (0) | 0 | 1 | 1 |
| 0 | 1 | 0 | |
| 0 | 3 | 0 | |
| 0 | 6 | 0 | |
| 0 | 12 | 0 | |
| 3 | 1 | 0 | |
| 3 | 1 | 1 | |
| LTE-M (1) | 0, 1 | 1–6 | 0 |
