摘要

在5G毫米波终端空口（over the air，OTA）射频一致性测试中，等效全向辐射功率（effective isotropic radiated power，EIRP）和总辐射功率（total radiated power，TRP）类测试是重要的OTA测试项。目前依靠 3GPP定义的随机扫描锁定最大波束的方式决定最大 EIRP 和 TRP，但该方法既耗时又缺乏准确性。提出一种非信令的测试方法，相比于目前的 EIRP、TRP 测试方法，不仅提高了准确性，而且使得非方向性 OTA 场地作为测量环境成为可能，进一步降低了测试成本和时间成本，并增加了测试环境选择的灵活度。

Abstract

In the 5G millimeter wave UE OTA RF conformance test

EIRP and TRP type of tests are important OTA items.Currently

this method relying on 3GPP-defined random scan to lock the beam to determine the maximum EIRP and TRP

but this method is time-consuming and lacks accuracy.A non-signaling test method was proposed

which could not only achieve more accurate measurements compared with the current EIRP and TRP test methods but also make it possible to use the non-directional OTA site as the measurement environment

further reducing the test cost and time cost

and increasing the flexibility of the test environment selection.
