5G NR Measurement Gap Configuration
A Mobile device has to measure the neighboring cells signal and other carrier components. Having a single RF module to control the Mobile manufacturing cost and form factor, device has […]
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 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 mmWave 28 GHz Band Link Budget – n257
The combination of 5G NR technology and millimeter wave bands pioneer a new level of mobile performance with ultra-high speeds and low latencies. Momentum behind 28 GHz is growing, with […]
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 NR Antenna Port – Logical and Physical Antenna Mapping
Downlink multi-antenna transmission is a key technology of 5G NR. Signals transmitted from different antennas ports will experience different “radio channels” even if the set of antennas are located at […]
5G NR Cell Access Control
Radio Access barring control refers to a traffic congestion control mechanism to secure and ensure the success of critical communications calls such as emergency calls by restricting connection requests from […]
5G NR Cyclic Prefix (CP) Design
Cyclic prefix (CP) refers to the prefixing of a symbol, with a repetition of the end In OFDM wireless systems. The receiver is typically configured to discard the cyclic prefix […]
5G NR Network Relationship – Neighbor Planning
In any telecommunication technology starting from 2G to 5G, Neighbor relation or to say Neighbor planning is an important activity. Neighbor relation information is very critical for cell re-selection while […]
