    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 transmitting IDs of cells of a specific type as physical cell ID information in addition to existing cell ID information is disclosed. For transmission of the physical cell ID information, the number of cell IDs used in transmitting the existing cell ID information on a synchronization channel is increased or a part of existing cell IDs are reserved for transmitting the additional specific-cell ID information. If the number of cell IDs is to be increased, the number of cell ID groups related to a secondary synchronization channel is increased in a manner that removes ambiguity and collision, a cell ID related to a primary synchronization channel is added, which satisfies conjugate symmetry, information is transmitted based on a transmission timing relationship between a primary synchronization code and a secondary synchronization code, or a scrambling scheme is modified. When a part of the existing cell IDs are reserved, conjugate symmetry is also considered in relation to a primary synchronization channel and ambiguity and collision are also considered in relation to a secondary synchronization channel.

    摘要： A method for transmitting a synchronization channel using multi-antenna is disclosed. In a method for transmitting a synchronization channel for using a synchronization channel as a phase reference when decoding a broadcast channel, the method includes using a pre-decided shift value for each antenna, wherein the shift value is pre-decided with a user equipment, so as to apply circular shifts to sequences of the synchronization channel, and transmitting the sequences having the circular shifts applied thereto from a base station to the user equipment. Herein, space frequency/time block codes (SFBC/STBC) may be applied to the broadcast channel. In performing time/frequency domain synchronization in the synchronization channel, regardless of the number of transmission antennae used by the base station when transmitting signals, the synchronization process may be performed. Also, multi-antenna gain may be obtained when transmitting the synchronization channel. Furthermore, channel estimation may be performed for each antenna, and by applying transmission diversity methods to the BCH/control channel/data channel and so on, the performance of the present invention may also be enhanced.
