TDD mode has not been emphasized on the whole in FDD mode in first and second generation mobile communication systems. However, due to the need for new services and the development of new technologies, and many advantages of the TDD mode, the TDD mode will be increasingly emphasized.
The working principle of time division duplex is as follows: TDD is a duplex scheme of a communication system for separating a reception channel and a transmission channel (or uplink and downlink) in a mobile communication system. In the TDD mode mobile communication system, the receiving and transmitting are in different time slots of the same frequency channel, namely carrier, and the receiving and transmitting channels are separated by using the guaranteed time; in the FDD mode, the receiving and transmitting are performed on two separate symmetric frequency channels, and the receiving and transmitting channels are separated by a guaranteed frequency band.
The characteristics and communication benefits of mobile communication systems employing different duplex modes are different. The uplink and downlink channels in the TDD mode mobile communication system use the same frequency, and thus have reciprocity of the uplink and downlink channels, which brings many advantages to the TDD mode mobile communication system. In TDD mode, the transmission of information in uplink and downlink can be performed on the same carrier frequency, i.e. the transmission of information in uplink and the transmission of information in downlink are realized by time division on the same carrier.
