Japanese operator NTT Docomo and compatriot vendor NEC Corporation have completed an interoperability testing for 5G Standalone (SA) using a 5G base station baseband unit (5G CU/DU) conforming to O-RAN open interface specifications and radio units (RUs) of different vendors.
In a release, the vendor said that the multi-vendor interoperability test used a software upgrade to introduce SA capability to NEC’s 5G Non-Standalone (NSA) CU/DU operating on NTT Docomo’s commercial network.
Going forward, the two companies aim to introduce the 5G CU/DU for NTT Docomo’s SA services in order to further expand its 5G services.
