Abstract
A method for determining the radio frame structure of a Time Division Duplex system is disclosed, which comprises: configuring, by the network side, the radio frame structure used for service transmission as containing two half-frames each of 5 ms, wherein each half-frame consists of eight service time slots of 0.5 ms and one special time slot field of 1 ms, two consecutive service time slots form a subframe of which the length is 1 ms, and the special time slot field contains a DwPTS, a GP and an UpPTS; determining the lengths of the DwPTS, the GP and the UpPTS in the special time slot field according to the requirements of the coverage range, and determining the radio frame structure used for service transmission. By reconfiguring the radio frame structure, the invention can flexibly support different coverage ranges, enhance the flexibility of satisfying different service requirements, and implement the coexistence of two types of TDD systems.
