`
`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.
