    • A random access preamble scheme involves generating first and second preambles, each preamble having at least two Zadoff-Chu (ZC) sequences, with the ZC sequences of the first preamble being different from the ZC sequences in corresponding positions of the second preamble. For example, between two different preambles that each have two different ZC sequences, the first ZC sequences of the two preambles are different from each other and the second ZC sequences of the two preambles are different from each other. In another embodiment, a receiving scheme involves transforming received ZC sequences into transformed ZC sequences. In an embodiment, the received ZC sequences are transformed by correlating the received ZC sequences with their one chip cycle-shifting sequence. Transformed ZC sequences can be used for correlation detection in a multi- user wireless communications system.
    • 随机接入前导码方案涉及生成第一前导码和第二前导码,每个前导码具有至少两个Zadoff-Chu(ZC)序列,其中第一前导码的ZC序列与对应的ZC序列不同 第二前导码的位置。 例如,在具有两个不同的ZC序列的两个不同的前导码之间,两个前导码的第一ZC序列彼此不同,并且两个前导码的第二ZC序列彼此不同。 在另一个实施例中,接收方案涉及将接收的ZC序列变换为变换的ZC序列。 在一个实施例中,通过将所接收的ZC序列与它们的一个码片循环移位序列进行相关来变换所接收的ZC序列。 转换后的ZC序列可用于多用户无线通信系统中的相关性检测。

    • A system and method for retransmission of a data segment in a wireless communication system. The system includes a transmitter, a receiver, and a retransmission manager. The transmitter transmits a data segment over a plurality of resource blocks. The data segment includes a plurality of data packets. Each of the data packets corresponds to one of the resource blocks. The receiver receives the data segment from the transmitter and determines that the data segment is incorrectly received. The retransmission manager initiates the retransmission of the data segment in response to the determination that the data segment is incorrectly received. The transmitter retransmits each of the data packets individually in sequence using the resource blocks originally assigned to the data packets.
    • 一种在无线通信系统中重传数据段的系统和方法。 该系统包括发射机,接收机和重传管理器。 发射机通过多个资源块发送数据段。 数据段包括多个数据分组。 每个数据分组对应于资源块之一。 接收机从发射机接收数据段,并确定数据段不正确接收。 响应于确定数据段被错误地接收到,重传管理器启动数据段的重传。 发射机使用原始分配给数据分组的资源块来顺序地重新发送每个数据分组。
