Abstract: A Synchronization Channel (SCH) transmission method includes generating a Primary SCH (P-SCH) sequence according to supplementary information. The supplementary information includes at least one of Base Station (BS) type information, Fast Fourier Transform (FFT) size information, BandWidth (BW) information, group information, sector information, and carrier type information. The method also includes modulating the P-SCH sequence and mapping the modulated P-SCH sequence to subcarriers within a predefined subcarrier set. The subcarriers are included in the subcarrier set being spaced one subcarrier interval apart. The method further includes generating a P-SCH symbol by Orthogonal Frequency Division Multiplexing (OFDM)-modulating the P-SCH sequence mapped to the subcarriers, and transmitting the P-SCH symbol.

Abstract translation: 同步信道（SCH）发送方法包括根据补充信息生成主SCH（P-SCH）序列。 补充信息包括基站（BS）类型信息，快速傅里叶变换（FFT）大小信息，带宽（BW）信息，组信息，扇区信息和载波类型信息中的至少一个。 该方法还包括调制P-SCH序列并将调制的P-SCH序列映射到预定子载波集内的子载波。 子载波被包括在间隔一个子载波间隔的子载波集合中。 该方法还包括通过正交频分复用（OFDM）生成P-SCH符号，调制映射到子载波的P-SCH序列，并发送P-SCH符号。
