    摘要: A wireless communication system is disclosed. A method for constructing a RACH preamble according to a cell radius of a base station (BS) irrespective of a guard time (GT) and a method for allocating the RACH preamble are disclosed. A method for constructing a preamble of a random access channel (RACH) includes acquiring time-length information of a predetermined cyclic prefix (CP) for each cell radius of a base station (BS), acquiring sequence time-length information of a single sequence or a repeated sequence, and constructing the preamble using the predetermined CP time-length information and the sequence time-length information, irrespective of a time length of a guard time (GT).

    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.

    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.
