PdcpLegJoiner¶

simple module PdcpLegJoiner

RX-side leg merger of a multi-leg PDCP entity (see PdcpEntityBase): relays the PDU streams of all legs into the single RX entity, whose one reorder window restores SN order across legs (the join needs no logic of its own – the SN space is common to all legs by construction).

Used in compound modules¶

Name	Type	Description
PdcpEntityBase	compound module	Base type of the PDCP entity of one data radio bearer: packages the transmitting and the receiving side of TS 36.323 / 38.323, plus the leg split/join stage of a multi-leg bearer (e.g. an NR dual connectivity split bearer). Created dynamically by BearerManagement, one per (peer, DRB) pair.

Properties¶

Name	Value	Description
display	i=block/join

Gates¶

Name	Direction	Size	Description
in [ ]	input		Per-leg input (sized by the enclosing PdcpEntityBase’s connections)
out	output		Merged stream to the RX entity
