Frame Structure 5G-NR In NR, similar to LTE, a radio frame is fixed to be 10 ms, which consists of 10 subframes each of 1ms. However, different from LTE which has a fixed subcarrier spacing (SCS) for 15 kHz, NR supports scalable numerology for more flexible deployments covering a wide range of services and carrier…
Master Information Block Direction: gnB=> UE Signalling Radio Bearer: N/A RLC-SAP: TM Logical Channel: BCCH Transport Channel: BCH The MASTER INFORMATION BLOCK (MIB) includes a limited number of most essential and most frequently transmitted parameters that are needed to acquire other information from the cell. The MIB is transmitted on BCH while all other SYSTEM INFORMATION messages are transmitted on DL-SCH The MIB is always transmitted on the BCH…
