Abstract: Methods and apparatuses are provided in a wireless communication system. Mini slot length information indicating mini slot length in a number of symbols is received from a base station via higher layer signaling. Downlink control information (DCI) including a number of mini slots for a hybrid automatic repeat and request (HARQ) feedback transmission is received from the base station. A mini slot for the HARQ feedback transmission is identified based on the mini slot length information and the number of mini slots for the HARQ feedback transmission. The HARQ feedback information is transmitted to the base station on a physical uplink control channel (PUCCH) based on the identified mini slot.
