Abstract:
1. A method for configuring a frame structure in a Long Term Evolution Time Division Duplex system, comprising: configuring the structure of a half-frame in a radio frame for traffic transmission in the system so that the half-frame comprises more than one normal sub-frames and at least one special sub-frame comprising a Downlink Pilot Time Slot, a Guard Period and an Uplink Pilot Time Slot; and determining the lengths of the Downlink Pilot Time Slot, the Guard Period and the Uplink Pilot Time Slot in the special sub-frame to determine the structure of the radio frame for traffic transmission; wherein, the half-frame is configured to comprise 1 special sub-frame and 4 normal sub-frames; and the lengths of the special sub-frame and each of the normal sub-frames are configured to be twice the length of a time slot in an existing frame structure type each of the normal sub-frames comprises 14 OFDM symbols in the case of short Cyclic Prefixes; and each of the normal sub-frames comprises 12 OFDM symbols in the case of long Cyclic Prefixes; and the length of the special sub-frame is 1 ms and the length of each of the normal sub-frames is 1 ms in the case that the length of a time slot in the existing frame structure type
