free5GRAN is an open-source 5G RAN stack. The current version includes a receiver which decodes MIB & SIB1 data. It also acts as a cell scanner. free5GRAN works in SA mode.
Redundancy version (RV )1 and 2 are not supported for LDPC decoding.
This means that when RV 1 or 2 is detected in DCI, receiver does not try to decode PDSCH.
When having found a cell with cells scanner, if RV is 1 or 2, you should run free5GRAN with cell search function with the found cell parameters and run free5GRAN until RV is 0 or 3 for decoding PDSCH and SIB1.
