    • A wireless communication method implemented in a communication system includes receiving a first data sequence, and processing the first data sequence to obtain information containing at least one of a first number and a sampling spacing associated with the first data sequence. The method also includes permuting the first data sequence to generate a permuted second data sequence. Permuting the first data sequence includes determining a first parameter based on at least one of the first number and the sampling spacing, determining a second parameter based on at least one of the first parameter, the first number, and the sampling spacing, and determining a mapping relationship between a j-th data item of the permuted second data sequence and an i-th data item of the first data sequence. The method further includes outputting the permuted second data sequence.
    • 在通信系统中实现的无线通信方法包括接收第一数据序列,并处理第一数据序列以获得包含与第一数据序列相关联的第一数量和采样间隔中的至少一个的信息。 该方法还包括置换第一数据序列以产生置换的第二数据序列。 排列第一数据序列包括基于第一数量和采样间隔中的至少一个来确定第一参数,基于第一参数,第一数量和采样间隔中的至少一个确定第二参数,并且确定 第二数据序列的第j个数据项与第一数据序列的第i个数据项之间的映射关系。 该方法还包括输出置换的第二数据序列。

    • A method for data transmissions in a wireless communication system includes: allocating resources for data to be transmitted; providing a seed number from the communication system; setting, based on the seed number, at least one parameter for a pseudo-random mapper having an input variable and an output variable; initializing an array with a number of base elements; increasing a current value of the input variable by a current value of a counter; and calculating a value of the output variable based on the pseudo-random mapper and the increased value of the input variable. The method further includes: swapping a first base element and a second base element in the array, the first base element being identified based on the current value of the counter, and the second base element being identified based on the value of the output variable; performing permutation on the resources by using the array as a permutation sequence; and transmitting the data.
    • 一种用于在无线通信系统中进行数据传输的方法包括:为要发送的数据分配资源; 从通信系统提供种子编号; 基于种子编号设置具有输入变量和输出变量的伪随机映射器的至少一个参数; 初始化具有多个基本元素的数组; 通过计数器的当前值增加输入变量的当前值; 以及基于所述伪随机映射器和所述输入变量的增加值来计算所述输出变量的值。 该方法还包括:交换阵列中的第一基本元素和第二基本元素,基于计数器的当前值识别第一基元,并且基于输出变量的值识别第二基元; 通过使用该阵列作为置换序列对资源执行置换; 并发送数据。
