name: NGEN-DC
full_form: NG-RAN E-UTRA-NR Dual Connectivity
context: For DL-TDOA signalling test cases a multi cell environment with NR Cell 1, NR Cell 2 and NR Cell 3 (if required) are used, as defined in 3GPP TS 38.508-1 [30]. All NR cells transmit DL-PRS according to the DL-PRS configuration provided in the DL-TDOA assistance data defined in subclause 8.4.1.8. Normal propagation condition is used for all cells. NR Cell 1 is the DL-TDOA reference cell. NR Cell 2 and NR Cell 3 are DL-TDOA neighbour cells. The simulated general NR environment as specified in 8.2.8 also applies. DL-TDOA tests are only applicable for Test Configuration B (Table 8.1A-1). The NR Cell 1, NR Cell 2 and NR Cell 3 frequencies to be used for testing and other default conditions are as specified for signalling test cases in 3GPP TS 38.508-1 [30].
description: NG-RAN E-UTRA-NR Dual Connectivity (NGEN-DC) is a 3GPP technology standard that enables dual connectivity between different radio access technologies. It allows simultaneous use of multiple radio bearers and configurations, improving network efficiency and user experience.
explanation: The text describes NGEN-DC as a technology standard within the context of failure handling scenarios in SCG/MCG frameworks. Its function is to define how dual connectivity operates under various conditions, placing it firmly within the realm of telecommunications technologies.
