Method and apparatus for reporting maximum transmission power in wireless communication

摘要

An information format and apparatus used by a base station to make a scheduling decision when the base station allocates resource to a terminal in a mobile communication system are provided. Operations of a terminal to report a maximum transmission power accurately to the base station in a scheduling process are also provided. A method for calculating a maximum transmit power in a constant manner regardless of a channel status is also provided.

1. A method for reporting a power headroom (PH) by a terminal in a mobile communication system, the method comprising:
detecting a power headroom report (PHR) triggering event; determining a maximum transmit power (PCMAX) value of the terminal for a serving cell; determining a power headroom (PH) of the terminal based on the PCMAX value; and transmitting a PHR including a PCMAX corresponding to the PCMAX value and the PH for the serving cell, to a base station, wherein the PCMAX value is determined based on a terminal power class and a maximum uplink transmit power allowed for the serving cell.
