Mobile station, base station, methods for transmitting and receiving power headroom report, and computer readable medium
First Claim
1. A method in a mobile station for transmitting a power headroom report, the method comprising:
- transmitting, to a base station, a power headroom report regarding activated first and second uplink carriers, the power headroom report including a first information element indicating a power difference between first maximum transmission power of the mobile station for the first uplink carrier and second maximum transmission power of the mobile station for the second uplink carrier.

Abstract
A mobile station (1) has a capability to communicate with a base station (2) simultaneously using activated first and second uplink carriers. The mobile station (1) is configured to transmit a power headroom report to the base station (2). The power headroom report includes an information element (ΔPPUSCH) indicating a power difference between first maximum transmission power of the mobile station (1) for the first uplink carrier and second maximum transmission power of the mobile station (1) for the second uplink carrier. It is thus, for example, possible to provide improvement of power headroom reporting (PHR) suitable for uplink carrier aggregation.
