TD-LTE Radio Frame Structure
TD-LTE Frame Structure (Type2) I
Each sub-frame occupies 1ms, the length of each timeslot is 0.5ms One half-frame(5ms) contains 10 timeslots, 8 traffic TS(0.5*8ms) and 2 special TS(1ms) 2 Special Timeslot: DwPTS, GP, UpPTS; Sub-carrier space:15KHz; RB= 12 sub-carrier span 1 slot 1 slot contains 7 Symbols (normal CP), 6 Symbols (extend CP)

In case of 5 ms downlink-to-uplink switch-point periodicity, the special subframe exists in both half-frames: Subframe No.1 and 6. In case of In case of 10 ms downlink-to-uplink switch-point periodicity, the special subframe exists in the first half-frame only. Subframe No.1.
