The network structure of LTE system is more flat and simple, which reduces the network node and system complexity, thus reducing system delay and reducing the network deployment and maintenance costs. The LTE system supports interoperability with other 3GPP systems. According to the different ways of duplex LTE system is divided into FDD-LTE (Frequency Division Duplexing) and TDD-LTE (Time Division Duplexing), the main difference between the two techniques in physical layer on the interface (such as frame structure, time synchronization design, etc.). FDD system interface using paired downlink band transmit and receive data, while the TDD system uses the same frequency band downlink transmission in different time slots, FDD duplex mode, TDD has a higher spectrum utilization rate.
