    摘要： A method for transmitting a preamble in a scalable bandwidth system is disclosed. The method includes transmitting a primary synchronization channel to which symbols are allocated at intervals of two or more subcarriers, through a specific bandwidth out of an entire system bandwidth at a start time point of a synchronization period, and transmitting a secondary synchronization channel through the specific bandwidth with a prescribed time difference from the primary synchronization channel at the synchronization period. A mobile station can use the same search routine irrespective of a system bandwidth, does not experience any difficulty at a cell edge in establishing signal timing synchronization, can simply perform preamble search, and can transmit a signal in a maximum usable bandwidth, thereby improving the accuracy of location measurement.

    摘要： A method for inserting parity into an FCH is disclosed. A method for inserting parity into a frame control header includes channel-encoding, by an additional channel encoder, a frame control header bit applied to a legacy encoder, and generating an additional codeword, and mapping the codeword generated by the legacy encoder and the additional codeword to subcarriers. This method inserts parity into the FCH, and defines a new FCH, such that it extends an FCH coverage simultaneously while maintaining a compatibility with a legacy system. Also, it may add additional energy to a legacy FCH or may give a coding gain to the same legacy FCH, such that it can extend information transferable using reserved bits of the FCH.

    摘要： A method for establishing a cyclic shift sequence to provide against the frequency offset is disclosed. The method calculates a distance between a channel response position of the sequence and an alias channel response position caused by a frequency offset, calculates the number of cyclic shifts per group according to the calculated distance, and establishes the cyclic shift (CS)—applying interval. This method easily establishes a cyclic shift (CS) interval at a specific location having no overlapping by considering a channel response of a reception (Rx) sequence and an alias location of this reception (Rx) sequence, although a reception (Rx) signal is shifted by a channel delay spreading or a propagation delay irrespective of categories of a domain generating a sequence, so that it can greatly reduce the number of the detection errors and the false alarm rate. And, if a sequence of the cyclic shift (CS) is allocated to a cell having a frequency offset of more than a predetermined level, the present invention can minimize the influence of a frequency offset on a high-mobility cell.

    摘要： A method for packet retransmission employing feedback information is disclosed. The method for packet retransmission employing feedback information comprises receiving reception acknowledgement information from a receiver after a transmitter transmits packets, the reception acknowledgement information representing channel status information and decoding success/failure of the packets; and changing a retransmission mode in accordance with the channel status information if the reception acknowledgement information represents decoding failure, and transmitting retransmission packets of the packets in accordance with the changed retransmission mode. Thus, it is possible to improve decoding probability of the receiver and increase efficiency of retransmission.

    摘要： A method for generating/transmitting a transmission-unit symbol sequence is disclosed. In the case of transmission information, the information is modulated in time and frequency domains on the basis of a predetermined transmission unit (e.g., a transmission time interval TTI or slot), simultaneous transmission of the information is made, and then a transmission unit symbol is generated/transmitted. A transmission sequence is masked in each symbol contained in one transmission unit. Symbol-unit circular shift (cyclic shift) is applied to the masked result, so that transmission efficiency increases. A control signal transmission method for supporting a variety of formats and a signal transmission method based on a prime-length sequence are also provided.
