Abstract: Method for signal generation in broadband wireless communications, comprises: A. modulating, segmenting and serial-parallel converting the signal data to be transmitted, then computing DFT of the serial-parallel converted data so as to transfer them to frequency domain; B. performing unit block modulating processing and block repeat modulating processing on the frequency domain data, then mapping the unit blocks to assigned time-frequency positions; C. computing IFFT of the mapped unit blocks, then adding them to the cycle prefix, thus the radon sequences in time domain are generated. Apparatus for signal generation, Method and system for message transmission in broadband wireless communications are also disclosed. The problem of resource allocation and scheduling, and problem of interference coordination and control are solved, the throughput and performance of communication system are greatly improved.

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 frequency offset correction method for wideband time division duplex cell communication system includes: receiving time domain sequences of the two pilot symbols having the scheduled interval in the time slot of transmitting broadcast channel; performing conjugate correlated operation between the two received pilot time domain sequences and the locally stored pilot time domain sequences corresponding to the pilot symbol; and performing the frequency offset correction according to the operation result. A method for cell first searching includes cell coarse synchronization , cell precise synchronization, cell coarse frequency offset correction and cell precise frequency offset correction, and the above frequency offset correction method is used to perform the cell precise frequency offset correction . The present invention increases the precision of frequency offset estimate in the user terminal, reduces the realization complexity at the same time, and provides an effective solution for realizing downlink synchronization and frequency offset correction by wideband time division duplex cell communication system.
