`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.

`Subframes 0 and 5 and DwPTS are always reserved for downlink transmission.
`
`The supported uplink-downlink allocations are listed in Table 4.2-2 where, for each subframe in a radio frame, “D”

`transmissions and “S” denotes a special subframe with the three fields DwPTS, GP and UpPTS. Both 5 ms and 10 ms
`switch-point periodicity is supported.
`
`In case of 5 ms switch-point periodicity, UpPTS and subframes 2 and 7 are reserved for uplink transmission.
`
`In case of 10 ms switch-point periodicity, DwPTS exist in both half-frames while GP and UpPTS only exist in the first

`Overview
`5.1
`The smallest resource unit for uplink transmissions is denoted a resource element and is defined in section 5.2.2.
`
`Physical channels
`5.1.1
`An uplink physical channel corresponds to a set of resource elements carrying information originating from higher
`layers and is the interface defined between 36.212 and 36.211. The following uplink physical channels are defined:
`
`- Physical Uplink Shared Channel, PUSCH
`
`- Physical Uplink Control Channel, PUCCH
`
`- Physical Random Access Channel, PRACH
`
`Physical signals
`5.1.2
`An uplink physical signal is used by the physical layer but does not carry information originating from higher layers.
`The following uplink physical signals are defined:
`
`- Reference signal
