Time Division Duplex is a wireless communication technique where transmission and reception are separated by time, where there is a time period for transmitting and a time period for receiving (often at the level of microseconds). This means that both uplink (from a mobile to a base station) and downlink (from a base station to a mobile) transmissions use the same frequency, at different allocated times. Times are often allocated by software or hardware configurations. Simultaneous transmission and reception is not possible. A useful analogy for TDD is a walkie-talkie, where only one user can talk (transmit) at any given time while all others are listening (receiving).
