Name	Type	Description
NrRlcAmRxEntity	simple module	NR (TS 38.322) receiving side of the Acknowledged Mode (AM) of the RLC layer: SO byte-coverage reassembly with a per-SDU SN window, t-Reassembly + t-StatusProhibit timers. Shares the common RlcAmRxEntityBase shell with the LTE profile LteRlcAmRxEntity. Bound by default inside the NrRlcAmEntity compound. The NR SO-reassembly statistics are declared here so they are recorded only for NR-selected entities.
