IRlcAmTxEntity

module interface

Transmitting side of an RLC AM entity: extends the generic TX interface with the gates over which the co-located receiving side hands it control PDUs (see RlcAmEntityBase).

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
LteRlcAmTxEntity	simple module	LTE (TS 36.322) transmission side of the Acknowledged Mode (AM) of the RLC layer: one AMD PDU per MAC grant built by concatenation (FI framing), the built PDU as the ARQ unit, NACK-driven retransmission with re-segmentation into AMD PDU segments, pollPDU/pollByte-driven status polling with t-PollRetransmit, and radio link failure at maxRtxThreshold retransmissions. Shares the common RlcAmTxEntityBase shell with the NR profile NrRlcAmTxEntity, whose ARQ skeleton it deliberately mirrors. Bound by default inside the LteRlcAmEntity compound.
NrRlcAmTxEntity	simple module	NR (TS 38.322) transmission side of the Acknowledged Mode (AM) of the RLC layer: byte-offset (SO) segmentation with re-segmentation on retransmission, pollByte/pollPDU-driven status polling. Shares the common RlcAmTxEntityBase shell with the LTE profile LteRlcAmTxEntity. Bound by default inside the NrRlcAmEntity compound. The NR SO-segmentation statistics are declared here so they are recorded only for NR entities.

Used in compound modules

Name	Type	Description
RlcAmEntityBase	compound module	Base type of the RLC AM entity of one data radio bearer: packages the transmitting and the receiving side into the single bidirectional entity of TS 36.322 / 38.322 section 4.2.1. Created dynamically by BearerManagement, one per (peer, DRB) pair.

Extends

Name	Type	Description
IRlcTxEntity	module interface	Module interface for the transmitting side of an RLC entity (TM/UM/AM). Concrete entity types (e.g. RlcTmTxEntity, RlcUmTxEntity, RlcAmTxEntity) implement this interface so that RlcTmEntity/RlcUmEntityBase/RlcAmEntityBase compound modules can instantiate them via a typename parameter. Implementations may declare additional gates (e.g. the AM control gates).
