NrPdcpRxEntity

simple module

Handles the operations related to the NR PDCP (Packet Data Convergence Protocol) layer on the receiving side of a specific connection. It extends the LtePdcpRxEntity module. Facilitates the creation of support for Dual Connectivity functionality. In particular, it manages the reordering of out-of-sequence PDCP PDUs in Dual Connectivity deployments.

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

Extends

Name	Type	Description
LtePdcpRxEntity	simple module	Handles the operations related to the LTE PDCP (Packet Data Convergence Protocol) layer at the receiving side of a specific connection. It processes incoming PDCP PDUs from the RLC layer, performing header decompression before forwarding them to the upper layer protocols.

Parameters

Name	Type	Default value	Description
binderModule	string	"binder"
headerCompressedSize	int	-1B	Header compressed size in bytes (-1B = compression disabled)
reorderingEnabled	bool	false	Set by a multi-leg PdcpEntityBase: reorder the SN stream merged from several legs
outOfOrderDelivery	bool	false
timeout	double	0.1s	Timeout for RX Buffer
rxWindowSize	int	4096
