4G LTE Important QXDM Log Packets
QXDM is most widely used tool in wireless 4G,5G technology to capture Qualcomm based Mobile signalling and data details logs for debugging purpose. Whether it is Field testing or Lab […]
5G NR RA-RNTI Calculation
A 5G UE picks a random preamble for RACH procedure to get the uplink synchronisation. The preamble is referenced with an ID know as RAPID (Random Access Preamble ID). 5G […]
5G NR RRC Timers, Counters and Constants
5G NR radio resource control (RRC) has introduced following listed timers, counters and constant for reliable functioning of procedures like RRCsetuprequest, RRCreestablishment, RRCresume, RRCsuspend etc. RRC timer indicates the timer […]
5G NR RRM Measurement Requirements
In 5G NR, the Sync Signal/PBCH block (SSB) burst is consists of multiple SSBs. These multiple SSBs are associated with the different SSB indexes and with the different transmission beams […]
5G NR Measurement Events
In any telecom technology (2G, 3G, 4G or 5G), mobility (handover) decision whether mobile device will be handover or not is taken by by base station based on measurement reports […]
5G NR Inactive-RNTI (I-RNTI) for RRC_INACTIVE State
In 5G NR, 3GPP specification has introduced an RRC state as RRC_INACTIVE state. The aim of RRC_INACTIVE state is to achieve power saving with acceptable access latency, and is suitable […]
5G NR Measurement – Serving Cell and Neighbor Cell
In 5G NR, for the procedures such as handover to a stronger cells or adding a new Carrier Component (CC) in the case of Carrier Aggression, it is required to […]
5G Identifiers SUPI and SUCI
In telecommunication systems, network operator allocate to each SIM card a unique identifier, known up to the 4G as an IMSI (International Mobile Subscriber Identity) and for the 5G as […]
5G NR System Information
System information is downlink broadcast information transmitted periodically by base station. it is very critical information for a mobile (UE) to connection the Base station (gNB in 5G) in any […]
5G System Connection Management: CM-Idle and CM-Connected
When a Mobile wants to communicate with 5G core network, as it first time switched-on or because it was in idle state for some time and network removed the resources […]
