PSS主同步信号数据捕获 （Initial Acquisition）
① [0xB113] LTE LL1 PSS Results ： 主同步信号结果，返回周围小区 接收功率 及 小区频点
PSS的全称是Primary Synchronization Signal，即主同步信号，用于传输组内ID即N(2)_ID值。
通过PSS 就能够找到子帧同步（时隙同步）以及小区索引。
PSS Peak Value：获取小区的接收功率
Peak Position： 小区频点
PSS Indicies：获得小区索引

SSS的全称是Secondary Synchronization Signal，即辅同步信号，用于传输组ID即N(1)_ID值。
通过SSS 能够确定信息在哪个子帧上，同时能获得在哪个组 （0 - 167共68个组）
结合前面PSS 获取到的小区索引，就能够计算出真正的物理小区ID (此处为 422)
