LteRlcAmRxEntity¶

//
// LTE (TS 36.322) receiving side of the Acknowledged Mode (AM) of the RLC
// layer: PDU-SN receiving window with byte-interval coverage for AMD PDU
// segments, t-Reordering + t-StatusProhibit, ACK_SN + NACK-list STATUS
// reports, in-order FI-walk reassembly of the concatenated SDU stream.
// Shares the common RlcAmRxEntityBase shell with the NR profile
// ~NrRlcAmRxEntity, whose window/status machinery it deliberately mirrors.
// Bound by default inside the ~LteRlcAmEntity compound.
//
simple LteRlcAmRxEntity like simu5g.stack.rlc.IRlcAmRxEntity
