Examples disclosed herein include a method performed by a wireless device for transmitting a Packet Data Convergence Protocol (PDCP) protocol data unit (PDU). The method comprises selecting one or both of a first path and a second path for transmitting the PDU to a destination based on a comparison of a first delay on the first path and a second delay on the second path, wherein the first delay includes a queueing delay and/or a processing delay on the first path, and/or the second delay includes a queueing delay and/or a processing delay on the second path. If both the first path and the second path are selected, the method comprises using carrier aggregation (CA) or dual connectivity (DC) to send the PDU to the destination on the first path using a first carrier and sending a duplicate of the PDU to the destination on the second path using a second carrier.
