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…
5GS Connection Management states Two CM states are used to reflect the NAS signaling Connection of the UE with the AMF: CM-IDLE CM-CONNECTED CM-IDLE state A UE in CM-IDLE state has no NAS signalling connection established with the AMF over N1. The UE performs cell selection/cell reselection according to TS 38.304 [50] and PLMN selection according to…
The 5G System architecture consists of the following network functions (NF). Service-based interfaces: This Service based interface is connected to each interface. The 5G System Architecture contains the following service-based interfaces: SBI Interface Namf Service-based interface exhibited by AMF Nsmf Service-based interface exhibited by SMF Nnef Service-based interface exhibited by NEF Npcf Service-based interface…
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…
