Throughout this specification, unless otherwise noted, the size of various fields in the time domain is expressed as a number of time unitsTs?1?15000?2048? seconds.
?Ts?10 ms duration. Two radio Downlink and uplink transmissions are organized into radio frames with Tf?307200frame structures are supported:
- Type 1, applicable to FDD, - Type 2, applicable to TDD.
4.1 Frame structure type 1
Frame structure type 1 is applicable to both full duplex and half duplex FDD. Each radio frame is Tf?307200?Ts?10 ms long and consists of 20 slots of lengthTslot?15360?Ts?0.5 ms, numbered from 0 to 19. A subframe is defined as two consecutive slots where subframe i consists of slots 2iand2i?1.
For FDD, 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions in each 10 ms interval. Uplink and downlink transmissions are separated in the frequency domain. In half-duplex FDD operation, the UE cannot transmit and receive at the same time while there are no such restrictions in full-duplex FDD.

transmissions and “S” denotes a special subframe with the three fields DwPTS, GP and UpPTS. The length of DwPTS and UpPTS is given by Table 4.2-1 subject to the total length of DwPTS, GP and UpPTS being equal
to30720?Ts?1 ms. Each subframe iis defined as two slots, 2iand2i?1 of length Tslot?15360?Ts?0.5 msin each subframe.
Uplink-downlink configurations with both 5 ms and 10 ms downlink-to-uplink switch-point periodicity are supported. In case of 5 ms downlink-to-uplink switch-point periodicity, the special subframe exists in both half-frames. In case of 10 ms downlink-to-uplink switch-point periodicity, the special subframe exists in the first half-frame only. Subframes 0 and 5 and DwPTS are always reserved for downlink transmission. UpPTS and the subframe immediately following the special subframe are always reserved for uplink transmission.
