前言:
这里主要介绍一下CA 技术里面,物理层主要工作。
参考:
载波聚合(CA)
目录:
1: CA 总体分析流程
2: CA 物理层
一 CA 总体分析流程
二 CA物理层
2.1 载波聚合LOG分析的相关包
1)0xB0C0 LTE RRC OTA Packet
2)0xB130 LTE LL1 PDCCH Decoding Result
3)0xB173 LTE PDSCH Stat Indication
4)0xB126 LTE LL1 PDSCH Demapper Configuration
5)0xB139 LTE LL1 PUSCH Tx Report
6)0xB193 LTE ML1 Idle Serving Cell Meas Response
7)0xB195 LTE ML1 Connected Neighbor Meas Request/Response
8)0xB16B LTE PDCCH-PHICH Indication Report
9)0xB111 LTE LL1 Rx AGC Log
10)0xB063 LTE MAC DL Transport Block
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.文章来源:https://www.toymoban.com/news/detail-730711.html
