NrRlcUmRxEntity¶

//
// NR (TS 38.322) receiving side of the Unacknowledged Mode (UM) of the RLC
// layer: SI + byte-offset (SO) reassembly with a per-SDU SN window and a
// t-Reassembly timer. Shares the common RlcUmRxEntityBase shell with the LTE
// profile ~LteRlcUmRxEntity. Bound by default inside the ~NrRlcUmEntity
// compound. The NR SO-reassembly statistics are declared here so they are
// recorded only for NR entities.
