LteRlcAmDataPdu¶

//
// LTE RLC AM data PDU: an AMD PDU or, when rf is set, an AMD PDU segment
// (3GPP TS 36.322 6.2.1.4 / 6.2.1.5).
//
// Concatenation is modeled exactly as in the UM data PDU (the inherited SDU
// list with per-SDU sizes plus the FI bits); an AMD PDU additionally carries
// the poll bit, and its sequence number (10-bit on the wire; unbounded in the
// model, as everywhere else) is the unit of ARQ.
//
// An AMD PDU segment -- a re-segmented retransmission built to fit a smaller
// grant -- carries the byte range [soStart, soEnd] of the original PDU's data
// field. As elsewhere in the model, the segment packet carries the original
// PDU's whole SDU list, and only chunkLength reflects the bytes on the air.
//
