IPdcpLegSplitter

module interface

Module interface for the TX-side leg dispatcher of a PDCP entity (see PdcpEntityBase): implementations pick the RLC leg for each PDCP PDU and apply that leg's id mapping. Instantiated by the PdcpEntityBase compound via a typename parameter when a leg needs it: on a multi-leg bearer, and on a single-leg bearer whose leg is not the anchor's (an SCG bearer).

Implemented by

Name	Type	Description
DcPdcpLegSplitter	simple module	TX-side leg dispatcher of a dual-connectivity split bearer (two legs), steering each PDCP PDU to a leg from the split policy RRC pushes off the bearer's definition (TS 38.331 PDCP-Config, TS 38.323 5.2.1). A splitter serves exactly one direction: a UE's TX side is uplink, a base station's is downlink.

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.
