Method and apparatus for transmitting uplink data in time sensitive network

An operation method of a terminal in a communication system, the operation method comprising:

• receiving a radio resource control (RRC) message from a base station, the RRC message including configuration information of a configured grant (CG) and time domain shift information for a CG resource indicated by the configuration information;
• transmitting a first signal to the base station through the CG resource;
• when a latency requirement is not satisfied by using the CG resource, shifting the CG resource in a time domain based on the time domain shift information;
• and
• transmitting a second signal to the base station through the shifted CG resource.

An operation method of a base station for receiving a signal including data, the operation method comprising:

• transmitting a radio resource control (RRC) message to a terminal, the RRC message including configuration information of a configured grant (CG);
• receiving a first signal from the terminal through a CG resource of the CG;
• when a latency requirement is not satisfied by using the CG, transmitting a control message to the terminal;
• and
• receiving a second signal from the terminal through a CG resource reconfigured based on the control message.
