    • A method forms a preamble sequence in a wireless communication system. The method comprises determining a value K related to a time-domain characteristic of the wireless communication system so that a time-domain preamble sequence includes a number of K waveforms similar in shape to one another having a linear phase shift, identifying a first preamble sequence for a first band, the first preamble sequence having a first length not dividable by K, identifying at least one second preamble sequence each for a second band, the at least one second preamble sequence having at least one second length, identifying the length of a third preamble sequence, the length of the third preamble sequence equal to a sum of the first length and the at least one second length, determining whether the time-domain characteristic is maintained when the one or more of the at least one second preamble sequence is concatenated with the first preamble sequence, modifying one or more of the at least one second preamble sequence if the time-domain characteristic is not maintained when concatenated, and forming the third preamble sequence by concatenating the first preamble sequence and the at least one second preamble sequence having one or more second preamble sequence modified.
    • 一种方法在无线通信系统中形成前导序列。 该方法包括确定与无线通信系统的时域特性相关的值K,使得时域前导序列包括具有线性相移的形状彼此类似的K个波形的数目,识别第一前同步码序列 对于第一频带,第一前导码序列具有不能由K划分的第一长度,标识每个用于第二频带的至少一个第二前同步码序列,所述至少一个第二前同步码序列具有至少一个第二长度, 第三前导码序列,第三前导序列的长度等于第一长度和至少一个第二长度的和,确定当至少一个第二前导码序列中的一个或多个是第一前导序列是否保持时域特性时 与第一前同步码序列连接,如果不保持时域特征,修改至少一个第二前同步码序列中的一个或多个 n级联,并且通过连接具有修改的一个或多个第二前同步码序列的第一前同步码序列和至少一个第二前同步码序列来形成第三前导序列。
