5G/NR - RAN Architecture - ShareTechnote
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 ...

5G标准冻结是什么意思？NR，NSA，SA，NG-RAN到底是啥意 …
5g里面有很多名词和简写，天天看通信新闻，说5g怎样怎样的，很多人不明白，这就做一个通俗的解释吧。 5G标准版本冻结： 我们经常看到新闻说5G独立组网标准版本冻结，但从来没有哪个新闻解释版本冻结是啥意思（可能发布新闻的记者也不懂），所以吃瓜群众 ...
5G NR - Wikipedia
5G NR (5G New Radio) [1] is a radio access technology (RAT) developed by the 3rd Generation Partnership Project for the 5G (fifth generation) mobile network. [1] It was designed to be the global standard for the air interface of 5G networks. [2]
5G System Overview - 3GPP
The 5G radio interface. 5G's radio technology is called NR (for New Radio). It is specified in TS 38.300 "NR; NR and NG-RAN Overall description; Stage-2". For layer 1: for the downlink (DL), i.e. network to UE, NR uses OFDM with Cyclic Prefix (CP) (similar to LTE).
5G Network Architecture. Core, RAN, & Security Architecture For 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 ...
5G network architecture | 5G Architecture - RF Wireless World
3GPP TS 38.401 describes 5G NR user plane and control plane as well as 5G NR RAN architecture with various interfaces (NG, Xn and F1) and their interaction with the radio interface (Uu).
NR frame structure: Sub-carriers and slots across frequency bands. MAC resource reservation, PDCP duplication and RLC windowing enhancements in 5G NR. Requires dedicated resources without simultaneous sharing. Can tolerate re-transmissions, can rely on both frequency as well as time diversity.

Apr 30, 2024 · 二、RAN定义 (RAN-Based Notification Area)是5G(NR)网络中新引入的一个新概念，也称为基于RAN的通知区域。 当UE移出RNA小区列表时需要报告其位置变化(类似于LTE中的TAU概念)，也就是进行基于RAN的通知区域更新(RNAU---通过服务ng-eNB或gNB触发)。
