name: NCR
full_form: Network-Controlled Repeater
context: A Network-Controlled Repeater node, referred to as NCR-node, is an RF repeater that enables wireless amplifying-and-forwarding functionality in NG-RAN. The NCR-node is capable of receiving and applying side control information from a gNB with additional functionality to support Network-Controlled Repeater. The NCR-node comprises an NCR-MT and an NCR-Fwd. The NCR-MT is an entity supporting a subset of the UE functionality that communicates with the gNB to receive side control information via a control link based on the NR Uu interface. The NCR-Fwd is the function performing amplifying-and-forwarding of signals between gNB and UE via the NCR-Fwd backhaul link and NCR-Fwd access link, respectively. The NCR-Fwd can support multiple beams towards the UE. The behaviour of the NCR-Fwd is controlled according to the side control information received from the gNB. The NCR-node is modelled as depicted in Figure 4.9.1-1. Figure 4.9.1-1: Conceptual model of network-controlled repeater. An NCR-MT establishes SRBs and, optionally, DRB(s) with a gNB. The establishment of DRB(s) can be used to transport OAM traffic. The signal that NCR-Fwd forwards is associated to the cell that the NCR-MT is connected to via the control link. Whether the NCR-Fwd can forward other signals is up to implementation.
description: A Network-Controlled Repeater (NCR) node is a type of RF repeater that enables wireless amplifying-and-forwarding functionality in Next Generation Radio Access Networks (NG-RAN). It consists of two main components: the NCR-MT and the NCR-Fwd. The NCR-MT communicates with the gNB to receive side control information via a control link based on the NR Uu interface, while the NCR-Fwd performs amplifying-and-forwarding of signals between the gNB and UE via the NCR-Fwd backhaul link and NCR-Fwd access link, respectively. The behavior of the NCR-Fwd is controlled according to the side control information received from the gNB.
explanation: NCR is classified as a Network Function because it serves as an intermediary component in NG-RAN that enables wireless amplifying-and-forwarding functionality, thereby extending the coverage and improving the quality of service. It interacts with other network functions such as the gNB to receive control information and forward signals between the gNB and UE.
