Could you please explain the relation between the value of RSRP (echoed from AT+QENG=“servingcell”) and the values of PRX,DRX,RX2,RX3 (echoed from AT+QRSRP)?
The AT commands manual says that RSRP indicates the signal of 5G NR Reference Signal Received Power. Range:-140 to -44 dBm.
and
PRX path RSRP value. Range: -140 to -44 dBm.
DRX path RSRP value. Range: -140 to -44 dBm.
RX2 path RSRP value. Range: -140 to -44 dBm.
RX3 path RSRP value. Range: -140 to -44 dBm.
For RM502Q-AE, I understand that it supports DL 4 x 4 MIMO, meaning that it can receive signals on all four antennas (e.g., QRSRP,-58,-71,-61,-61,NR5G) to leverage space diversity, or spacial multiplexing.
How these four values are processed to produce the RSRP in the AT+QENG=“servingcell” command?
Thanks for any help/comment.
