Abstract: A method and apparatus are provided for transmitting power headroom information by a terminal in a mobile communication system. The method includes receiving, by the terminal, information on an allocated uplink transmission resource; determining whether a path loss has changed more than a threshold, after transmitting last power headroom information, when the terminal has the allocated uplink transmission resource; if the path loss has changed more than the threshold when the terminal has the allocated uplink transmission resource, determining a transmission of the power headroom information; and transmitting an uplink packet including the power headroom information using the allocated uplink transmission resource. The power headroom information is obtained based on a difference between a maximum transmission power of the terminal and a transmission power of the terminal.
