The half Frame (field) that the radio frames of 10ms is 5ms by two length among the TD-LTE forms, and the subframe (subframe) that each Half Frame is 1ms by five length forms, and four common subframes and a special subframe are wherein arranged.Common subframe is made up of the slot (time slot) of two 0.5ms, and special subframe is made up of three special time slots, and these three special time slots are respectively UpPTS, GP and DwPTS.The TD-LTE frame structure as shown in Figure 1.
Each radio frames length of TD-LTE is T f=307200T s=10ms, each field are T f=153600T s=5ms, the length SFn=30720T of a subframe s=1ms (n=0,1...4).
The special subframe of TD-LTE is made up of following three special time slots: DwPTS, GP and UpPTS.The config option of each slot length of special subframe as shown in Table 1.
The allocation list of table one, TD-LTE special time slot length
Figure G2008101879947D0000011
Wherein, the length of DwPTS is 3～12 OFDM (OFDM) symbols; The length of UpPTS is 1～2 OFDM symbol; GP is used for the conversion of up-downgoing, mainly is made of " propagation delay time " and " equipment transmitting-receiving conversion time delay ".
