- 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.
