Abstract: An operation method of a terminal in a communication system includes receiving an RRC message from a base station, the RRC message including configuration information of a plurality of CGs; transmitting a first signal to the base station through a first CG resource indicated by a first CG among the plurality of CGs; receiving a control message from the base station; and based on a result of receiving the control message, transmitting a second signal to the base station through a second CG resource indicated by an activated second CG among the plurality of CGs, wherein a pattern of the first CG resource is different from a pattern of the second CG resource.

Abstract: A method and an apparatus for uplink communication based on grant-free scheme in a communication system. An operation method of a terminal includes receiving an RRC message from a base station, the RRC message including information indicating a frequency resource of a PUSCH; receiving a DCI from the base station, the DCI including information indicating a time resource of the PUSCH; and transmitting the PUSCH to the base station using the time-frequency resource indicated by the RRC message and the DCI. Therefore, the performance of the communication system can be improved.
