1. A method of operating a wireless device in a radio access network, the wireless device being configured with a slot configuration according to which a slot has multiple subslots, the method comprising:
transmitting acknowledgement information reporting on subject transmission in a subslot based on a received timing indication indicating a subslot number for transmitting the acknowledgement information, and based on a subslot offset, the timing indication being represented by a bit pattern in a downlink control information message, the bit pattern being interpreted differently depending on whether a fixed Hybrid Acknowledgement Repeat Request (HARQ) codebook is used or a dynamic HARQ codebook is used.
