在HSDPA发射功率测试过程中,要求的ACK-NACk,CQI的设置为:
Set Ack-Nack Repetition Factor to 3 .
Set CQI Feedback Cycle (k) to 4 ms .
Set CQI Repetition Factor to 2 . [/COLOR]
ACK-NACK Rpetition Factor的意义是什么呢,我知知道在HSDPA中需要设置TTI(Transmission Time Intervla)的值,这个值决定了
我HSDPA 下行数据的间隔,可是为什么还需要设置ACK-NACK Rpetition Factor和CQI这些参数呢? 关于CQI Feedback Cycle的定义是:
This parameter sets the CQI feedback cycle value signalled to the UE, which controls how often the UE transmits new CQI information on the
uplink.[/COLOR]
还有CQI Repetition Factor的定义是:This parameter sets the CQI repetition factor signalled to the UE, whice controls how often the UE repeats CQI information on the uplink).[/COLOR]这里所提到的重复是重复什么呢,跟我们设置的TTI 又是一个什么关系呢 |
