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) 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. A method performed by a
user equipment (UE) includes: receiving downlink data and / or downlink control signaling from a
base station; determining uplink data and / or uplink control signaling, an uplink time unit and / or an uplink physical channel for transmitting the uplink data and / or the uplink control signaling based on the downlink data and / or the downlink control signaling; and transmitting the uplink data and / or uplink control signaling to the
base station on the determined uplink time unit and / or uplink physical channel.
