RlcTmTxEntity¶
Package: simu5g.stack.rlc.tm
simple module RlcTmTxEntity
Implements the transmission side of the Transparent Mode (TM) of the Radio Link Control (RLC) layer for a specific connection. Buffers SDUs from the upper layer and, upon receiving a MAC SDU request, sends the next queued PDU without segmentation or concatenation.
