Abstract: Methods and apparatuses are provided in which a radio resource control (RRC) message is transmitted to a terminal. A set of values for a timing between a physical downlink shared channel (PDSCH) and acknowledgement information is included in the RRC message, and the set of values is respectively associated with a set of numbers of a transmission time interval (TTI). First downlink control information (DCI) for a first PDSCH is transmitted to the terminal. A number of bits associated with one value in the set of values is included in the DCI. The first PDSCH is transmitted to the terminal. Acknowledgement information for the first PDSCH is received from the terminal, based on a transmission timing determined by using the RRC message and the number of bits in the DCI.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure relates to a method and apparatus for transmitting uplink (UL) data in a wireless communication system. A method includes receiving configuration information for a grant-free UL transmission, the configuration information including information on a number of repetitive transmissions and period information; identifying resources for repetitive transmissions in a period based on the configuration information; identifying a resource for an initial transmission of the UL data based on a value of a redundancy version (RV) associated with the resource, wherein the resource for the initial transmission of the UL data is associated with an RV value 0; and performing the initial transmission of the UL data on the identified resource.

Abstract: A communication method for a channel access in a wireless communication system and an apparatus therefor are provided. The communication method includes an evolved NodeB (eNB) that transmits data to a user equipment (UE) through a licensed band, and determines whether an unlicensed band channel is in an idle state during a first channel sensing duration. If the unlicensed band channel is in the idle state, the eNB transmits data to the UE through an unlicensed band during a first channel occupying duration, a second channel sensing duration, and a second channel occupying duration. In the method, a sum of the first channel occupying duration, the second channel sensing duration, and the second channel occupying duration is equal to or less than a certain time.
