    Abstract: A method is described for a specific user equipment (UE) to perform a random access to a Node-B within a cell in which a plurality of UEs are located together. The method includes receiving system information for at least one of a basic sequence index and a length of a zero correlation zone (ZCZ) from the Node-B, and transmitting a preamble sequence to the Node-B over a random access channel. The preamble sequence is generated from constant amplitude zero auto-correlation (CAZAC) sequences distinguishable by at least one of the basic sequence index and a length of a cyclic shift (CS) applied to the preamble sequence. The length of the CS applied to the preamble sequence is given by one among a plurality of application lengths determined based on the length of the ZCZ, wherein a number of the plurality of lengths are differently given based on a type of the specific UE, and wherein the system information is the same for all the UEs within the cell regardless of the types of UEs.

    Abstract translation: 描述了一种用于特定用户设备(UE)对多个UE位于一起的小区内的节点B进行随机接入的方法。 所述方法包括从节点B接收基本序列索引和零相关区域(ZCZ)的长度中的至少一个的系统信息,以及通过随机接入信道将前导码序列发送到节点B。 从通过基本序列索引和应用于前导序列的循环移位(CS)的长度中的至少一个可以区分的恒定幅度零自相关(CAZAC)序列生成前导码序列。 应用于前导序列的CS的长度由基于ZCZ的长度确定的多个应用长度之一给出,其中基于特定UE的类型不同地给出多个长度的数量,以及 其中系统信息对于小区内的所有UE是相同的,而与UE的类型无关。
