Abstract:
1. A power headroom reporting method comprising: transmitting power headroom information of one of a first transmission mode and a second transmission mode from a mobile station to a base station, a first maximum transmissible power of the first transmission mode being different from a second maximum transmissible power of the second transmission mode, wherein each of the first transmission mode and the second transmission mode is an uplink transmission mode from the mobile station to the base station, and each of the first maximum transmissible power and the second maximum transmissible power is an uplink transmissible power of the mobile station; transmitting difference information indicating a difference between the first maximum transmissible power and the second maximum transmissible power to the base station before transmitting the power headroom information; and transmitting an uplink signal with the uplink transmission mode, which is determined between the first transmission mode and the second transmission mode based on the power headroom and the difference information.
