8.4.2.3 Correct behaviour at Time-out Fail 求助

05-08

3GPP TS 34.121中8.4.2.3(Correct behaviour at Time-out) Fail
Spec:The UE shall transmit 2 preambles cycles, consisting of 12 preambles in each preamble cycle.
实际测试结果:First cycle: 8 second cycle: 11
关于此测试项的描述如下:The UE shall stop transmit preambles when reaching the maximum number of preambles allowed in a cycle. The UE
shall then repeat the ramping procedure until the maximum number of preamble ramping cycles are reached. No ACK/NACK shall be sent by SS during this test.
The UE shall transmit 2 preambles cycles, consisting of 12 preambles in each preamble cycle.
其他测试项都Pass,只有这个Fail了,有没有大神能解释下这个测试项,如何去解决?
可以用高通工具QXDM来改善么?
之前尝试过NV Item:533和534 NV_WCDMA_TX_LIN_VS_TEMP_0/1_I 都加了15
改后First cycle变成了7 second cycle还是11.
求大神的帮助~~

没太看懂,是不是:“小区不发送接入指示,后来的各种请求(语音、数据)不能打断当前的连接情况下,导码循环包括12个导码手机要发送最少2个循环?”
百度了一下PRACH和P-CCPCH,这个是物理层、MAC层、RRC层的。求大神。
8.4 RRC Connection Control
8.4.2 Random Access
8.4.2.3 Correct behaviour at Time-out
