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

② [0xB115] LTE LL1 SSS Results : 辅同步信号结果,

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)

SRB 描述
SRB0 不需要建立,上下行就有的
SRB1 需要建立,它主要用于上下行的信令 和 部分NAS 信令
SRB2 需要建议,用于NAS层的消息
