Radio Access Network (6)

CARel-10

Carrier Aggregation

The combination of multiple component carriers to increase a UE's effective bandwidth and peak data rate.

TS 36.300TS 38.300

EN-DCRel-15

E-UTRA New Radio Dual Connectivity

A non-standalone 5G deployment option where a UE connects simultaneously to an LTE eNodeB (master) and an NR gNodeB (secondary), sharing an EPC core.

TS 37.340TS 36.300

NSARel-15

Non-Standalone

A 5G deployment architecture where NR radio is anchored by an existing LTE/EPC control plane, most commonly realized as EN-DC.

TS 37.340

SARel-15

Standalone

A 5G deployment architecture where the gNodeB connects directly to the 5G core (5GC) without relying on an LTE anchor.

TS 23.501TS 38.300

eNodeBRel-8

Evolved Node B

The LTE radio base station, combining the functions of the UMTS Node B and RNC into a single flat-architecture element that terminates the radio interface and connects directly to the EPC.

TS 36.300TS 36.401

gNodeBRel-15

Next Generation Node B

The 5G NR base station, capable of connecting to both 5GC (via NG) and, in non-standalone mode, acting as a secondary node alongside an eNodeB.
