I find below table probably the best way to remember about LTE frame structure.
| Configuration | (FDD)Frame Type 1 | (TDD) Frame Type 2 | |
| Frame Length | 10 ms | 10 ms | |
| Subframes per Frame | 10 | 10 | |
| Subframe Length (ms) | 1 | 1 | |
| Slots per Subframe | 2 | 2 | |
| Symbols/Slot, normal CP | 7 | 7 | |
| Symbols/Slot, extended CP | 6 | 6 |

what’s the difference between frame type 1 FDD and frame type 2 TDD?
