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 for an allocated uplink transmission resource; identifying whether a path loss has changed by more than a threshold, after transmitting last power headroom information, when the terminal has the allocated uplink transmission resource; in case that the path loss has changed by 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 based on 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.

Abstract: Drive testing for network optimization has been supplemented by the use of information measuring radio conditions collected by mobile terminals (i.e. UEs). To improve the user experience of multicast and broadcast services based on cellular telecommunications networks, such as MBMS and eMBMS, a mechanism is described that adapts UE-based reporting of measurement reports to multicast and broadcast services.
