Aug 8, 2022 · The NR base stations (logical node "gNB") connect with each other via the Xn interface, and the Access Network (called the "NG-RAN for SA architecture") connects to the 5GC network using the NG interface.

3GPP TS 38.401 version 15.2.0 Release 15 6 ETSI TS 138 401 V15.2.0 (2018-07) 1 Scope The present document describes the overall architecture of the NG-RAN, including interfaces NG, Xn and F1 interfaces

Mar 31, 2020 · This article explains details of the 5G gNodeB (gNB) architecture and choices for Central Unit (CU) and Distributed Unit (DU) Split (CU DU Split) How is the gNodeB Comprised? The logical architecture of gNB is shown in figure below with …

Oct 18, 2024 · Non-Terrestrial Networks are included in 3GPP specifications for 5G. By placing a complete gNB on the satellite, Rel-19 will enable greater network integration.

Explore the architecture of 5G networks, including the 5G NR architecture, RAN elements, protocol stack, and key components as defined by 3GPP.

3GPP RAN3 has delivered the NG-RAN architecture that is a solid yet flexible foundation for 5G. "5G and Beyond" contains contributions by leading experts, active in 3GPP.

Sep 21, 2022 · As per 3GPP, The gNB is divided into two logical functions: the CU and DU. The DU is the baseband unit in a 5G RAN. It handles layer 1 and layer 2 processing and fulfills critical functions such as coding/decoding, scheduling, MIMO processing, and beamforming.

Jan 26, 2021 · These are some high level functions of 5g gNB from 3gpp release 15: gNB does Radio Resource Management such as Radio Bearer Control, Radio Admission Control, Connection Mobility Control. Mac scheduling: Dynamic allocation of resources to UEs in both uplink and downlink.

This page describes 5G NR Handover Types, specifically focusing on 5G Inter gNB handover and 5G intra RAN handover (C-Plane Handling). This information aligns with specifications from 3GPP, as documented in 3GPP TS 38.300.

Jan 9, 2024 · Implementing CU/DU split options in NTN achieves the following: Reduce the complexity onboard the satellite compared to a full gNB onboard. Reduce the bandwidth and the signaling towards the core network (over the feeder link). …
