Communication method and apparatus in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a radio resource control (RRC) message including first information configuring a medium access control (MAC) parameter for the terminal;
• and
• transmitting, to the terminal, an uplink grant on a physical downlink control channel (PDCCH) addressed to a cell radio network temporary identifier (C-RNTI),
• wherein the first information includes second information indicating to the terminal whether to skip an uplink transmission, and
• wherein whether to skip a generation of a MAC protocol data unit (PDU) associated with the uplink grant is identified based on the second information.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• receive, from a base station, a radio resource control (RRC) message including first information configuring a medium access control (MAC) parameter for the terminal,
• identify second information indicating to the terminal whether to skip an uplink transmission, the second information being included in the first information,
• receive, from the base station, an uplink grant on a physical downlink control channel (PDCCH) addressed to a cell radio network temporary identifier (C-RNTI), and
• identify whether to skip a generation of a MAC protocol data unit (PDU) associated with the uplink grant based on the second information.
