AmTxEntity

simple module

This module implements the transmitting functionalities of the Acknowledged Mode (AM) of the Radio Link Control (RLC) layer for a specific connection. It stores packets coming from the Packet Data Convergence Protocol (PDCP) layer into a transmission buffer and, upon notification of a transmission opportunity from the Medium Access Control (MAC) layer, sends down a RLC Protocol Data Unit (PDU) of the appropriate size (possibly performing segmentation and/or concatenation). It implements an Automatic Repeat reQuest (ARQ) mechanism to enable the retransmission of unacknowledged RLC PDUs

Parameters

Name	Type	Default value	Description
fragmentSize	int	30B	Size of fragments
maxRtx	int	3
pduRtxTimeout	double	2.0s
ctrlPduRtxTimeout	double	2.0s
bufferStatusTimeout	double	2.0s
txWindowSize	int	16

Properties

Name	Value	Description
dynamic	true
display	i=block/segm
