Abstract: In accordance with the example embodiments of the invention there is at least a method and apparatus to perform determining, by a device of a communication network, that at least one PDCP PDU of a PDCP sublayer is duplicated for transmission over at least one logical channel; signaling to an RLC sublayer an indication of the at least one PDCP PDU that is duplicated; and based on the signaling, controlling duplication of the at least one PDCP PDU for transmission over the at least one logical channel. Further, there is at least a method and apparatus to perform receiving, at a device of a communication network, an indication through a received signaling indicating that at least one PDCP PDU of a PDCP sublayer is to be duplicated; determining to duplicate the at least one PDCP PDU; duplicating the at least one PDCP PDU based on the determination; and transmitting the duplicated PDCP PDU over at least one logical channel.
