1、LTE数据传送过程
Data transmission in LTE
2、MTK TPUT Checklist
仅仅以LTE为例进行介绍
2.1、检查CellInfo
1.These information can be obtained from following path of ELT
EM->4G->EL1->EL1 statistics->protocol 1/protocol 2
scell information: EM->4G->EL1->EL1 statistics（Scell）
或搜索 MSG_ID_EM_EL1_STATUS_IND in Ps integrated，参考MTK FAQ28400
2.2、检查CA能力
Modem搜索CA band combination
2.3、EPS参数
参考MTK FAQ28402
2.3、Layer3参数
参考MTK FAQ28413

如果问题是UL慢，还需要看DUT 和 REF 的UL能力是否一致：
SBP_DISABLE_UL64QAM_WHEN_CA_DISABLED
2.5、Layer1参数
DL 参考MTK FAQ28414
UL 参考MTK FAQ28403/28404
2.6、是否使用同一server
