For example, anew radio communication system may benefit from a flexible indication of transmission timing. A method may include determining, at the user equipment, transmission timing based on a first parameter and a second parameter. The first parameter may indicate an offset as a number of slots. The second parameter may indicate an offset as a number of symbols within one of the slots. The method may also include using the transmission timing to at least one of send an uplink transmission or receive a downlink transmission. ## Claims ### Claim 1 A method comprising: determining, at a user equipment, transmission timing based on a first parameter indicating an offset as a number of slots and a combined parameter comprising a second parameter and a fourth parameter, wherein the second parameter indicates an offset as a number of symbols within one of the slots and the fourth parameter indicates a duration of the transmission as the number of symbols within one of the slots;
