请问大家，马上开始搞5G了，准备开始接触下5G的协议，目前看到有下面几部：
TS 38.211 NR; Physical channels and modulation
TS 38.212 NR; Multiplexing and channel coding
TS 38.213 NR; Physical layer procedures for control
TS 38.214 NR; Physical layer procedures for data
TS 38.215 NR; Physical layer measurements
System architecture milestone of 5G Phase 1
TS 23.501 – System Architecture for the 5G System; Stage 2
TS 23.502 – Procedures for the 5G System; Stage 2
TS 23.503 – Policy and Charging Control Framework for the 5G System; Stage 2
