First communication device, second communication device and methods performed therein for controlling transmission

A method performed by a second communication device for controlling transmission of one or more data packets in a wireless communication network, the method comprising:

• receiving an indication, from a first communication device, indicating one or more of the following:
• a maximum number of duplicates allowed to be transmitted for each data packet, a type of duplication, a data radio bearer (DRB) for which duplication is configured, a radio link control (RLC) entity that is allowed to transmit a duplicate, an order of RLC entities in which the second communication device should transmit a first data packet and following duplicates, and whether the duplication is activated or deactivated for a DRB;
• and
• handling communication based on the received indication, the handling comprises receiving duplicates according to a first duplication process and/or a second duplication process, based on whether the first communication device decided to activate the first duplication process and/or the second duplication process, and/or deactivate the first duplication process and/or the second duplication process for one or more DRBs,
• wherein the first duplication process implies that the duplicates are transmitted over same RLC entities over time, and the second duplication process implies that the duplicates are transmitted on a need basis and/or are transmitted over RLC entities that can change over time.

A first communication device for controlling transmission of one or more data packets in a wireless communication network, wherein the first communication device comprises a communication interface and processing circuitry associated with the communication interface, the processing circuitry is configured to:

• transmit an indication to a second communication device adapted to indicate one or more of the following:
• a maximum number of duplicates allowed to be transmitted for each data packet, a type of duplication, a data radio bearer (DRB) for which duplication is configured, a radio link control (RLC) entity that is allowed to transmit a duplicate, an order of RLC entities in which the second communication device should transmit a first data packet and following duplicates, and whether the duplication is activated or deactivated for a DRB;
• and
• decide whether to activate a first duplication process and/or a second duplication process, and/or deactivate the first duplication process and/or the second duplication process for one or more DRBs,
• wherein the first duplication process implies that the duplicates are transmitted over same RLC entities over time, and the second duplication process implies that the duplicates are transmitted on a need basis and/or are transmitted over RLC entities that can change over time.

A second communication device for controlling transmission of one or more data packets in a wireless communication network, wherein the second communication device comprises a communication interface and processing circuitry associated with the communication interface, the processing circuitry is configured to:

• receive an indication, from a first communication device, adapted to indicate one or more of the following:
• a maximum number of duplicates allowed to be transmitted for each data packet, a type of duplication, a data radio bearer, (DRB) for which duplication is configured, a radio link control (RLC) entity that is allowed to transmit a duplicate, an order of RLC entities in which the second communication device should transmit a first data packet and following duplicates, and whether the duplication is activated or deactivated for a DRB;
• and
• handle communication based on the received indication, the handling comprises receiving duplicates according to a first duplication process and/or a second duplication process, based on whether the first communication device decided to activate the first duplication process and/or the second duplication process, and/or deactivate the first duplication process and/or the second duplication process for one or more DRBs,
• wherein the first duplication process implies that the duplicates are transmitted over same RLC entities over time, and the second duplication process implies that the duplicates are transmitted on a need basis and/or are transmitted over RLC entities that can change over time.
