Antenna Port定義
1. 因此FBRX跟TX的Antenna Port只會有”0” for L/M Band & “4” for H Band
2. 目前ZS620KL只support B3跟B7 4X4 MIMO

RFM Device definition (I)
1. RFM Device is actually the location of the corresponding VCO
RFM Device 0~7 indicate RX path
2. RFM Device 8= TX Chain 0
9= TX Chain 1

ULCA Path
1. FBRX & TX Antenna Port only have ”0” for L/M Band & “4” for H Band
2. RFM Device only have “8” for CH0 &“9” for CH1
3. according to support ULCA B7 will have two paths, one of which is B7 ULCA, which can
determine if B7 TX is abnormal

DL CA Path(II) PRX OLN1030
B3(There are 10 signal path)
DRX OLN1030
B3 CA : When the B3+B7 (4*4) combination is used ,it is use
L/MB+B7* upside antenna, so the position is "2"

DL CA路徑(II)
B7(會有18條signal path)
PRX OLN1030
DRX OLN1030
B7 CA : When the B3(4*4)+B7 combination is used, it is use HB
upside antenna, so the position is "6"
