其中, 基站可以通过高层信令向 UE发送数据扰码的初始化序列配置参数。
其中, UE确定数据扰码的初始化序列配置参数后, 根据所述数据扰码的初始化序列配 置参数生成数据扰码的初始化序列可以具体如下:

[ ns /2」 + 1)·(2Χ+1)·216+ ¾NTI for PUCCH format 2/2a/2b 其中, X为 UE确定的数据扰码的初始化序列配置参数, Wrnti为 RNTI (Radio Network Temporary Identifier,无线网络临时鉴定)的编号, g是码字的编号, q=0或 1,对于 ePDCCH, g可以为一个固定的数值, 如 ^=0或 g=l, 为 RF中时隙 slot的标号。
