Jan 24, 2023 · The 5G RAN architecture is composed of multiple nodes and components that work together to provide seamless connectivity to users. These nodes include the User Equipment (UE), the Base Station (BS), the Central Unit (CU), and the Distributed Unit (DU).

Nov 13, 2022 · 5G network architecture will be using C-RAN (Cloud Radio Access Network) for better and ultra-fast internet. 5. 4G uses modulation techniques like QAM (Quadrature Amplitude modulation) and QPSK (Quadrature Phase shift keying). 5G is said to be using the Amplitude Phase-Shift Keying technique.

3GPP TS 38.401 describes 5G NR user and control planes and the RAN architecture, including interfaces (NG, Xn, and F1) and their interaction with the radio interface (Uu). 5G smartphones interact with 5G-RAN over the Uu radio interface, while 5G …

The 5G core network architecture is at the heart of the new 5G specification and enables the increased throughput demand that 5G must support. The new 5G core, as defined by 3GPP, utilizes cloud-aligned, service-based architecture (SBA) that spans across all 5G functions and interactions including authentication, security, session management ...

As shown in Figure 1, the architecture of the 5G RAN systems will consist of macrocell and smallcells (i.e., microcell, picocell, femto- cell, relay and device to device (D2D)) based...

RAN Architecture. Overall Architecture of NR RAN (Radio Access Network) would not look much different from LTE RAN Architecture. However getting into details, you would start seeing some differences as well. You see different name of each node and interface. MME/S-GW in LTE is replaced by AMF/UPF in NR and X2/S1 in LTE are replaced by Xn/NG-C/U ...

In this paper, we investigate the problem of dynamic RAN slicing mapping under the sliding scheduled traffic model in metro-access/aggregation elastic optical networks (EONs).

Main Objectives of 5G/5G-Advanced •Ultra-flexible radio-access configurations •Higher bandwidth •Higher spectral efficiency (bits/s/Hz/m2) •Bandwidth parts • Tailor bandwidth to UE class (like eMTC narrowbands/widebands) •New abstractions for service classification down to L1 (slicing) •Compatibility with 4G/5G core network

The following diagram illustrates various 5G Core Control Plane functions. The UPF and RAN components are User Plane Functions responsible for radio control, packet routing, Deep Packet Inspection (DPI), and other router-based functions.
