Method and apparatus for transmitting power headroom information in a communication system

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

• transmitting, to a terminal, system information including first uplink waveform information for an initial access;
• receiving, from the terminal, a radio resource control (RRC) connection request message based on the first uplink waveform information;
• transmitting, to the terminal, an RRC connection response message including second uplink waveform information for an uplink data transmission;
• and
• receiving, from the terminal, data based on the second uplink waveform information.

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

• a transceiver;
• and
• a controller configured to:
• receive, from a base station, system information including first uplink waveform information for an initial access;
• transmit, to the base station, a radio resource control (RRC) connection request message based on the first uplink waveform information;
• receive, from the base station, an RRC connection response message including second uplink waveform information for an uplink data transmission;
• and
• transmit, to the base station, data based on the second uplink waveform information.
