Abstract
There is provided mechanisms for triggering uplink PDU duplication from a user equipment. A method is performed by a network node. The method comprises configuring the user equipment with an RLC URLLC mode. According to the RLC URLLC mode the user equipment is configured with an RLC trigger for the user equipment to perform uplink PDU duplication for an URLLC service.

A method for triggering uplink protocol data unit, PDU, duplication from a user equipment, the method being performed by a network node, the method comprising:
- configuring the user equipment with a radio link control, RLC, ultra-reliable low latency, URLLC, mode, wherein according to the RLC URLLC mode the user equipment is configured with an RLC trigger for the user equipment to perform uplink PDU duplication for an URLLC service, wherein, according to the configuring, the PDUs for the URLLC service is, upon transmission, immediately considered to be negatively acknowledged regardless whether positive or negative acknowledgement is received from the network node.
