Стандарт LTE непрерывно развивается. Основным усовершенствованием в версии 10 (LTE-Advanced) была технология объединения несущих (CA). В версиях 11 и 12 в стандарт LTE добавлено несколько новых компонентов. Улучшены некоторые имеющиеся функции (например, усовершенствована технология CA) и добавлены совершенно новые концепции, такие как координированная передача и прием (CoMP).В этом документе кратко описываются решения для испытаний от Rohde & Schwarz для сетей LTE-Advanced версий 11 и 12, в которых используются векторные генераторы сигналов, анализаторы сигналов и спектра и широкополосный радиокоммуникационный тестер.

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.
