前言：

    这里主要介绍一下CA 技术里面，物理层主要工作。

参考：

  3.1 载波聚合LOG分析的相关包

 Idle 状态下 服务小区测量：
.
                PCell and SCell measurements

3.2 UE decodes PDCCH on both SCC and PCC

  

 3.3  ML1 RLM Report

       RLM BLER/SNR is calculated only on PCell.

       

    3.4： PDSCH Stat Indication
.
         Serving cell index indicates the respective grant on PCell and SCell.
.
         Each CC has an independent HARQ process i.e., 8 HARQ IDs per CC.

        

  3.5  LL1 PUSCH Tx Report

3.6  PUSCH Tx Report
.
Number of ACK/NACK bits is 4. In the example below, the UE sends ACKS for both DL MIMO streams on PCC and SCC.

3.7  LTE LL1 Rx Agc Log
.
Rx AGC log packet for both PCC and SCC are printed individually.
