APPARATUS AND METHOD FOR TRANSMITTING POWER HEADROOM INFORMATION IN A MULTI-CARRIER SYSTEM |
摘要 |
<p>A method of transmitting a power headroom (PH) by a user equipment (UE) in a multi-carrier system is provided. The method includes: receiving power determination information from a base station (BS); determining a plurality of maximum transmission power values for a plurality of serving cells by using the power determination information and a UE specific parameter; determining a plurality of PHs on the basis of the plurality of maximum power transmission values; and transmitting the plurality of maximum transmission power values and the plurality of PHs to the BS. Accordingly, since the maximum transmission power value and the power headroom information are provided to the BS, reliable carrier aggregation scheduling can be induced, thereby being able to improve uplink transmission capability.</p> |
