SpletThe PBCH data bits are CRC-checked, 1/3 convolutionally encoded, interleaved, repeated and then scrambled. By decoding the PBCH bits and exploiting the repetition and CRC … Splet19. nov. 2024 · 5G 考试基础试题(含答案) 一、单项选择题 1、5G NR 帧结构的基本时间单位是( C ) A) subframe B) slot C) Tc D) symbol 2、5G 无线帧长是多少 ms(B) A) 5 B) 10 C) 20 D) 40 3、EN-DC 中,MCG 进行 NR 邻区测量使用的参考信号 (A ) A) SSB RS B) CSI-RS C) C-RS D) DM-RS 4、EN—DC 中,下面哪种测量目前协议未定义(C) A ... SpletBefore user equipment (UE) can communicate with the network, it must perform cell search and selection procedures and obtain initial system information. The first steps in that process are acquiring frame synchronization, finding out the cell identity and decoding the MIB and SIB1. This example shows how to perform these steps by using 5G Toolbox. how to sell slime on etsy
