Response
''

Execution Command

Execute the below Command to query the carrier aggregation (CA) information

AT+QCAINFO
Response
+QCAINFO: "PCC",<freq>,<bandwidth>,<band>, <pcell_state>,<PCID>,<RSRP>,<RSRQ>,<RSSI>,<SINR> 
+QCAINFO: "SCC",<freq>,<bandwidth>,<band>, <scell_state>,<PCID>,<RSRP>,<RSRQ>,<RSSI>,<SINR>
+QCAINFO: "SCC",<freq>,<bandwidth>,<band>, <scell_state>,<PCID>,<RSRP>,<RSRQ>,<RSSI>,<SINR>
If no active secondary cell
