A communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT) is provided. The method includes intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a packet processing method of a transmitter that include transmitting a radio link control (RLC) service data unit (SDU) to a receiver; receiving, from the receiver, a first message including information about whether the RLC SDU is successfully transmitted; and transmitting a first indicator indicating successful transmission of the RLC SDU from an RLC entity of the transmitter to a packet data convergence protocol (PDCP) entity of the transmitter when the receiver receives the RLC SDU.

A wireless device receives configuration parameters indicating a first logical channel of a bearer, configured with duplication, mapped to a first base station distributed unit (DU) and a second logical channel of the bearer mapped to a second base station DU. Based on activation of duplication for the bearer, the wireless device transmits first data of the first logical channel via the first base station DU and second data of the second logical channel via the second base station DU.

A media data transmission and processing system and a method for operating the system is a suggested. The media data transmission and processing system comprises two independent processing cards. The system is configured such that if one of the two processing cards fails, then the system is still capable of one downstream data stream. A key role in place the Master Slave configuration between the two processing cards. The Master processing card is configured to assign a new PTP timestamp and packet counter number to an IP packet currently processed in the Master processing card and to communicate the new PTP timestamp and packet counter number to the Slave processing card, which assigns the same PTP timestamps and packet counter numbers as the Master processing card.

In accordance with the example embodiments of the invention there is at least a method and apparatus to performing 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, performing 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.

Embodiments of this application provide a communication processing method. A data volume report reported by a terminal device includes a data volume on one of at least two paths in a radio bearer in a duplication mode, so that signaling overheads in a data volume reporting process of the terminal device can be reduced.

A method of activating and deactivating data duplication and a terminal thereof are provided. The method of activating and deactivating data duplication includes: receiving, by a protocol layer entity of the terminal, a command sent by a network side for deactivating or activating a data duplication of a bearer; and instructing, by the protocol layer entity, other protocol layers of the terminal to deactivate or activate a data duplication function of the bearer.

A communication system includes a transmission-side processing device, and a reception-side processing device, the transmission-side processing device and the reception-side processing device communicate using a plurality of communication lines, wherein the transmission-side processing device concurrently transmits the same telegraphic messages via each of the plurality of communication lines, and the reception-side processing device is capable of concurrently receiving telegraphic messages via each of the plurality of communication lines, and when a same telegraphic message as a previously received telegraphic message is received later, invalidates the same telegraphic message received later while processing the previously received telegraphic message.
