    • 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.
    • 公开了一种使用多天线发送同步信道的方法。 在对广播频道进行解码的同步信道的同步信道的发送方法中,作为相位基准的方法,该方法包括对每个天线使用预定的移位值,其中,移位值由用户设备预先决定, 以便对同步信道的序列应用循环移位,并且将从基站向其发送的具有循环移位的序列发送给用户设备。 这里,空间频率/时间块码(SFBC / STBC)可以应用于广播频道。 在同步信道中执行时间/频域同步时,无论发射信号时基站使用的发射天线的数量如何,都可以执行同步处理。 此外,当发送同步信道时可以获得多天线增益。 此外,可以对每个天线执行信道估计,并且通过将传输分集方法应用于BCH /控制信道/数据信道等,也可以提高本发明的性能。
