1. A method for use in a network node of a frequency division duplex, FDD, wireless communication network, the method comprising,
scheduling, for a wireless device operating in the FDD wireless communication network, a first downlink transmission with a first transmission processing time on a first frequency carrier, the scheduling comprising a first downlink assignment index, DAI, the first DAI comprising a first total DAI and a first accumulative DAI;
scheduling, for the wireless device, a second downlink transmission with a second transmission processing time different than the first processing time on a second frequency carrier, the scheduling comprising a second DAI, the second DAI comprising a second total DAI and a second accumulative DAI, wherein the first transmission processing time and the second transmission processing time relate to a respective hybrid automatic repeat request, HARQ, feedback transmission timing corresponding to the first downlink transmission and the second downlink transmission, and wherein the network node expects HARQ feedback for the first downlink transmission and the second downlink transmission in a single uplink transmission; and
transmitting the scheduling for the first and second downlink transmission to the wireless device.
