LTE UL MCS deteriorate after upgrade BW from 10M to 15 ! (huawei)

Dear LTE experts,

We noticed that UL MCS deteriorate after bandwith upgrade from 10M to 15M

Any explanation please ?

Higher BW, higher is the amount of PRBs for the same limited UL UE Tx Power, lower is the amount of power per PRB, thus, you may see some KPIs being "impacted", but in fact, the user experience should be increased.
