空口(OTA)性能是衡量无线终端发射和接收信号质量的重要指标之一.为兼顾5G无线终端的OTA限值及其它性能指标与成本控制要求,文章从测试样品种类、数量、测试数据处理等方面研究了单输入单输出(SISO)OTA测试频段1限值的制定方法.5G无线终端空口性能限值的制定使用累计分布函数(CDF)分析样品测试数据,测试样品类型应足够丰富,样品数量50~100即可,通常取80%样品能通过的数值作为行业标准限值制定的参考值.归纳整理的限值制定方法可为5G无线终端OTA行业标准限值的制定提供参考.
Over the air(OTA)performance is one of the important indicators for measuring the quality of signals transmitted and received by wireless terminals.In order to balance the OTA limit and other performance indicators and cost control requirements of 5G wireless terminals,this article studies the method of setting the limit for single input and single output(SISO)OTA testing frequency band 1 from the aspects of sample type,quantity,and test data processing.The development of OTA performance limit for 5G wireless terminals uses the cumulative distribution function(CDF)to analyze sample test data,and the test sample type should be rich enough,and the number of samples can be 50 to 100,and the value that 80%of samples can pass is usually taken as the reference value of the industry standard limit.The summarized limit formulation method provides a reference for the development of the 5G wireless terminal OTA industry standard limit.
