摘要

A method for a PDCP duplication function for a UE configured with first and second cell groups is provided. The method receives, through RRC signaling, a configuration for a PDCP entity. The configuration indicates an association between the PDCP entity and several RLC entities, each associated with one of the first and second cell groups, a first RLC entity in the RLC entities associated with the first cell group to be a primary RLC entity, and a second RLC entity in the RLC entities associated with the second cell group to be a secondary RLC entity. The method duplicates at least one of one or more PDUs, and submits the at least one and a duplicate of the at least one of the one or more PDCP PDUs to the primary RLC entity and at least another one of the plurality of the RLC entities respectively.
