Abstract: A method using a frame structure which supports relay for wireless transmission, which divides the time slots of a sub-frame into some zones, in which the data is transmitted using the manner of TDD, wherein further including that at least one time slot in a sub-frame is set as a hybrid zone; the transmission of the data is realized through frequency division multiplexing the access link and relay link in the hybrid zone of the sub-frame; and also the multi-hop relay is supported under the two work manners of relay in sub-frame and relay in frame.

Abstract: A method for determining data transmission offsets comprises synchronization matching a first time division duplex TDD system with a second TDD system (a500); determining a transmission timing advance of the user terminal, in the establishing processing of the uplink synchronization of the second TDD system, according to the deviation between the random access time and the expected time of the user terminal (a501); determining the offsets of the time slots of the second TDD system according to the time difference of the time slots of the first TDD system and the second TDD system(a502); acquiring the data transmission offsets of the time slots by adding the determined time slot offsets and the transmission timing advance(a503). A system and base station for determining the data transmission offsets are provided. The present invention solves the problem of the interference between two TDD systems that are co-located in adjacent channel frequency.

Abstract: A method for determining the radio frame structure of Time Division Duplex (TDD) system is disclosed, which comprises: the network side configures the radio frame structure used to transmit service information as follows: a radio frame includes two 5 ms half-frames, and each half-frame is divided into eight service slots of duration 0.5 ms each and one special slot field of duration 1 ms; two consecutive service slots form a subframe, and the length of the subframe is 1 ms; the special slot field includes DwPTS, GP and UpPTS. According to the demand of coverage sphere, the lengths of DwPTS, GP and UpPTS in the special slot field are determined, and the radio frame structure used to transmit service information is determined. Through the reconfiguration of the radio frame structure, this invention realizes flexible support for different coverage sphere, and increases the flexibility of satisfying different demand of service, and implements the coexistence of two kinds of TDD systems.

Abstract: A method, apparatus and system for transmitting signal, the method includes: using the weighting factor sequence, processing weighting repeating modulation for the basic cell block mapped by the data symbol block at the sending end, and obtaining a plurality of the repeating cell blocks corresponding to the said basic cell block; the sending end maps each repeating cell block to the appointed time-frequency position respectively, then sends the signals in the said time-frequency position; and the receiving end demodulates the plurality of data symbol blocks from the blocks, and incorporates the plurality of data symbol blocks; the said receiving end demodulates the incorporated data symbol blocks, and generates the received data. This scheme can be called as the block repeating spread diversity transmission technology for short, it is based on the information symbol in the time-frequency domain two-dimensional grid point. This scheme doesn't restrict the modulating signal generation manner at bottom, it can form a new multiple address/multiple path transmission scheme, and can be incorporated with the other key technologies in the existing mobile communication.
