Name	Type	Description
LteRlcAm	simple module	This module implements the functionalities of the Acknowledged Mode (AM) of the Radio Link Control (RLC) layer. At the transmitting side, 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 (via segmentation and/or concatenation). At the receiving side, it stores RLC PDUs arriving from the MAC layer in order to perform reassembly and in-sequence delivery of packets to the PDCP layer. It implements an Automatic Repeat reQuest (ARQ) mechanism to retransmit unacknowledged RLC PDUs at the transmitting side and provide guaranteed delivery at the receiving side.
