Abstract: The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. According to an embodiment of the present disclosure, a method performed by a terminal in a communication system is provided. The method comprises the steps of: confirming a maximum data rate supported by the terminal; confirming an instant data rate on the basis of the number of slots corresponding to one transport block (TB); confirming whether or not the maximum data rate satisfies the condition of being equal to or greater than the instant data rate; and transmitting or receiving data on the basis of whether or not the condition is satisfied.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method for improving the coverage of an uplink channel for uplink transmission is provided. The method includes receiving, from a base station, configuration information including resource allocation information for transport block (TB) processing over multiple slots (TBoMS), repetitive transmission configuration information, and frequency hopping information, identifying whether repetitive transmission of the TBoMS is configured, based on the configuration information, determining a frequency hopping pattern between TBoMS repetitive transmissions based on the frequency hopping information and a number of slots for frequency hopping in case that the repetitive transmission of the TBoMS is configured, and performing the repetitive transmission of the TBoMS based on the frequency hopping pattern.
