METHODS FOR POWER HEADROOM REPORTING, RESOURCE ALLOCATION, AND POWER CONTROL

摘要

PROBLEM TO BE SOLVED: To provide a method for reporting power headroom and methods for resource allocation and power control using the method for reporting power headroom which is suitable to cases in which transmissions over both PUCCH and PUSCH are allowed in the same subframe.SOLUTION: A method for reporting power headroom in the terminal includes the steps of: determining whether or not the terminal is set so as to conduct both PUSCH transmission and PUCCH transmission in the same subframe; and allowing the terminal in which the settings that the PUSCH transmission and PUCCH transmission can be conducted in the same subframe are made to report to a base station the power headroom obtained by subtracting PUSCH transmission power and PUCCH transmission power from the maximum transmission power defined on the basis of a class of the terminal and the power headroom obtained by subtracting the PUSCH transmission power from the maximum transmission power defined on the basis of the class of the terminal, when an event requesting power headroom reporting occurs.
