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：
