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。
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.
