LTE-TDD, also called TD-LTE in China, is the time division long-term? Time-sharing Long-term Evolution (Time-sharing long-term evolution) is jointly formulated by the major global enterprises and operators covered by the 3GPP organization. The FDD and TDD modes in LTE standard are essentially the same, with only a small difference, and the similarity is 90%.
TDD time division duplex is one of the duplex technologies used in mobile communication technology, which corresponds to FDD frequency division duplex.
TD-LTE is the TDD version of LTE technology, and FDD-LTE technology is the FDD version of LTE technology. TD-SCDMA is CDMA (Code Division Multiple Access) technology, while TD-LTE is OFDM (Orthogonal Frequency Division Multiplexing) technology. They are different in coding and decoding, frame format, air interface, signaling and network architecture.
Extended data
TD-LTE, as an important opportunity in the transition period of communication industry, mainly includes three characteristics:
1. It contains a large number of patents from China, led by China, and has gained extensive international support and become an international standard;
2. Fast Internet access, which can reach dozens of times that of TD-SCDMA technology, making it possible to access the Internet at high speed everywhere;
3. The rapid development of the industry has basically achieved the synchronous development with other international mobile broadband technologies, representing the most advanced level of the mobile communication industry in the world today.
