EVOLVED PACKET DATA CONVERGENCE PROTOCOL DUPLICATION

摘要

Some of the present implementations provide a method for a PDCP duplication function for a UE that is configured with a first cell group and a second cell group. The method receives, from a base station, 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 further generates one or more duplicated PDCP PDUs, and transmits the generated duplicated PDCP PDUs to at least the first and second RLC entities.
