    • A method and radio communication system for synchronizing subscriber stations, wherein a time slot is assigned to a number of base stations for transmitting at least one synchronization sequence and adjacent base stations use a different time offset with respect to the beginning of the time slot for transmitting the synchronization sequence. Thus, superposition can be precluded even in the case of a synchronized operation of the base stations. So that the subscriber station can still determine the beginning of the time slot, the time offset is transmitted. The time offset corresponds to the choice of one or more synchronization sequences and/or the sequence of a number of synchronization sequences. The information relating to the time offset is transmitted coded in this manner. A subscriber station receives the synchronization sequence and performs a time synchronization via the time of reception of the synchronization sequence and the detected synchronization sequence designating the time offset and/or the detected sequence of a number of synchronization sequences.
    • 一种用于同步用户站的方法和无线电通信系统,其中将时隙分配给多个基站用于发送至少一个同步序列,并且相邻基站使用相对于发送时隙的开始的不同时间偏移量 同步序列。 因此,即使在基站的同步操作的情况下也可以排除叠加。 因此,用户站仍然可以确定时隙的开始,发送时间偏移。 时间偏移对应于一个或多个同步序列的选择和/或多个同步序列的序列。 以这种方式对与时间偏移有关的信息进行编码。 订户站接收同步序列,并通过接收同步序列的时间和所指定的时间偏移量的检测到的同步序列和/或检测到的多个同步序列的序列来执行时间同步。
