Title:
A method and a device which transmit the usable electric power information on the terminal in a mobile communication system
Document Type and Number:
Japanese Patent JP6049078
Kind Code:
B2
Abstract:
A method for transmitting power headroom information by a terminal in a mobile communication system, the method comprising: receiving, by the terminal, information on an allocated uplink transmission resource and information on a threshold; determining whether a path loss has changed more than the 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, wherein 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, and wherein the transmission power of the terminal is obtained using the path loss and information related to a Modulation Coding Scheme, MCS.
