1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions thereon that, when executed by the at least one processor, cause the apparatus to perform at least:
determining a deactivation of packet data convergence protocol (PDCP) data duplication for a radio bearer configured for PDCP data duplication, wherein the radio bearer configured for PDCP data duplication is associated with an original radio link control (RLC) entity and a duplicate RLC entity; and
responsive to said deactivation,
determining that the duplicate RLC entity has remaining duplicated data to be transmitted after said deactivation,
causing mapping of a logical channel associated with the duplicate RLC entity of the radio bearer to at least one active cell associated with the original RLC entity of the radio bearer, and
transmitting the remaining duplicated data of the duplicate RLC entity on the logical channel to the at least one active cell.
