LteRlcUmRxEntityD2D¶

simple module LteRlcUmRxEntityD2D

D2D-capable LTE (TS 36.322) RLC UM receiving entity: LteRlcUmRxEntity plus the D2D_MULTI single-PDU reordering window, the post-mode-switch reassembly resynchronisation, and the D2D branch of the throughput/delay statistics.

Inheritance diagram¶

Extends¶

Name	Type	Description
LteRlcUmRxEntity	simple module	LTE (TS 36.322) receiving side of the Unacknowledged Mode (UM) of the RLC layer: FI-walk reassembly across concatenated PDUs with a PDU-SN reordering window and a t-Reordering timer. Shares the common RlcUmRxEntityBase shell (MAC-mux plumbing, D2D hooks, UL burst-throughput accounting) with the NR profile NrRlcUmRxEntity. Bound by default inside the LteRlcUmEntity compound. Its throughput/delay statistics are emitted on the sibling rlcMux module (see RlcMux).

Parameters¶

Name	Type	Default value	Description
macModule	string	“^.^.mac”	Set by the enclosing RlcUmEntityBase compound (per leg)
rlcMuxModule	string	“^.^.rlcMux”	This bearer’s leg mux; set by the RlcUmEntityBase compound
timeout	double	1s	Timeout for RX Buffer
rxWindowSize	int	16	PDU reorder window

Properties¶

Name	Value	Description
class	LteRlcUmRxEntityD2D
display	i=block/layer
dynamic	true

Gates¶

Name	Direction	Size	Description
in	input		PDUs from MAC, via the RlcMux
out	output		Reassembled SDUs to the PDCP layer (direct per-DRB connection, not via a mux)
