作者: tinaxia 标题: SS/PBCH block in 5G new radio

u为了支持波束扫描，同步信号块被组织成一系列脉冲串（burst），并周期性发送

•Period ???

•SS/PBCH blocks occur with a periodicity of 2 frames

u SS/PBCH block consists of 4 consecutive OFDM symbols and 24 RBs

•The minimum bandwidths of 24 RBs are supported by all 5G UE

•For PSS and SSS, the resources are mapping to the middle 127 subcarriers

•For PBCH, the resource is mapping to the 288 subcarriers (i.e., 24 RBs)

uThe same CP length and subcarrier spacing for PSS, SSS, PBCH

•Subcarrier spacing configuration: 15 kHz, 30 kHz, 120 kHz and 240 kHz
