O LTE está em constante desenvolvimento. A versão 10 (LTE-Advanced) introduziu a agregação de portadora (CA) como melhoria principal. As versões 11 e 12 adicionam diversos componentes novos ao LTE. Algumas são melhorias em recursos existentes (como melhorias no CA), enquanto outras são conceitos totalmente novos, como o multiponto coordenado (CoMP).Esta nota de aplicação resume as soluções de teste da Rohde & Schwarz para o LTE-Advanced de acordo com as versões 11 e 12 usando os geradores de sinal vetorial, analisadores de espectro e sinal e o testador de comunicação via rádio de banda larga.

The Global Certification Forum (GCF) has approved the first two radio ressource management (RRM) conformance test cases for 5G FR2 frequencies, implemented on the R&S TS-RRM-NR 5G RRM conformance test system from Rohde & Schwarz. The test cases have been validated in seven FR2 and LTE band combinations. With this success, Rohde & Schwarz is leading the way in validated test cases for the technically challenging FR2 mmWave frequency bands.

The R&S TS-RRM-NR 5G conformance test system from Rohde & Schwarz is the first test platform to achieve test platform approval criteria (TPAC) from the GCF certification organization for 5G radio resource management (RRM) at FR2 frequencies. As a consequence, the first RRM conformance FR2 work items have reached “active” status, making them mandatory for mobile device certification. RRM FR2 test cases with one and two angles of arrival (1xAoA and 2xAoA) have been validated in multiple FR2 EN-DC band combinations.
