Abstract: A method for managing carrier aggregation (CA) duplication in a network entity is provided. The method includes configuring a plurality of carrier paths in at least one radio link control (RLC) entity of the network entity, configuring at least one path as a primary path and at least another path as a secondary path from among the plurality of configured carrier paths based on a path configuration criteria, selecting at least one of the primary path and the secondary path for transmission of data packets based on at least one of the path configuration criteria and a packet-specific criteria, and transmitting the data packets on the selected paths.

Abstract: Embodiments herein provide a method performed by a user equipment (UE) for handling packet data convergence protocol (PDCP) duplication. In one embodiment, the method includes determining that a first criteria to deactivate the PDCP duplication is met based on a first device condition; and sending, to a base station, a first message indicating a first preference to deactivate the PDCP duplication. In other embodiment, the method also includes determining that a second criteria to activate the PDCP duplication is met based on a second device condition; and sending, to the base station, a second message indicating a second preference to activate the PDCP duplication.
