[PDF] 5g ng ran architecture

The 5G?standalone access architecture requires the deployment of a 5G core network connected to the next?generation radio access network (NG?RAN). The NG?RAN provides both NR and LTE radio access. The NG?RAN provides both an LTE radio interface and a 5G?NR radio interface.

  • What is 5G RAN architecture?

    5G is about connecting things everywhere while enabling new use cases. A 5G Radio Access Network (RAN) relies on a fully coordinated, multi-layer network with low-band, mid-band and high-band to provide wireless connectivity to devices and deliver the best network performance.

  • What are the components of 5G RAN architecture?

    5G RAN Architecture
    The gNB incorporates three main functional modules: the Centralized Unit (CU), the Distrib- uted Unit (DU), and the Radio Unit (RU), which can be deployed in multiple combinations. The primary new interface is the F1 interface between DU and CU This are expected to be interoperable across vendors.

  • What is the RAN area in 5G?

    The 5G RAN includes a sub-state called “RRC Inactive”. In this state, air interface resources are released but the device's context remains on the last serving gNB.
  • Today, RAN architecture divides the user plane and the control plane into separate elements. The RAN controller can exchange one set of user data messages through a software-defined networking switch and a second set through a control-based interface.
