In a TDD mode mobile communication system, different time slots on the same frequency channel (i.e., carrier) are received and transmitted, and the reception and transmission channels are separated by the guaranteed time.
The TDD system has the following characteristics:
(1) It does not require paired frequencies, can use various frequency resources, and is suitable for asymmetric uplink and downlink data transmission rates, and is particularly suitable for IP type data services;
(2) The uplink and downlink work at the same frequency, and the symmetrical characteristics of the wave propagation make it easy to use new technologies such as smart antennas to achieve the purpose of improving performance and reducing costs.
