Set correct values of the puncturing scheme and the retransmission flag
The puncturing scheme and the RBS flag must be set according to certain rules in TS 44.060 (184.108.40.206, 220.127.116.11, ...). Currently they puncturing scheme 1 is always used and RBS is always 0. It must be updated and remembered per BSN. The RBS flag must be set, if at least one BSN data block in the RLC block is being retransmitted.
