GCF认证失败

各位大神，有没有做过GCF认证的，有几个指标失败了，但是不知道怎说整改，求大牛支招~~~~~~~~感激不尽！

Transmit Modulation PRACH preamble quality
Power control in downlink / Power control in the downlink, constant BLER target
Demodulation of Paging Channel (PCH)
FDD inter frequency measurements - Correct reporting of neighbours in fading propagation condition (Release 6 and later)
Reporting of Channel Quality Indicator - Single Link Performance - Fading Propagation Conditions
Reporting of Channel Quality Indicator - Open Loop Diversity Performance - Fading Propagation Conditions
Reporting of Channel Quality Indicator - Closed Loop Diversity Performance - Fading Propagation Conditions

协议问题 多测几次就过了

这么多FAIL项，还是先准备状态已知的样机复测，估计是单个问题。
不要过分相信认证实验室，实验室也会出现误测的，经常遇到。
