Patent ID: 7929472

Claim:
A method for uplink scheduling in a mobile communication system performing communication using a plurality of sub-carriers, the method comprising the steps of: transmitting scheduling-related information including power information in relation to a transmission power of a User Equipment (UE) to a Node B; receiving resource allocation information indicating a resource area including entirely consecutive sub-carriers or a resource area including partially consecutive sub-carriers from the Node B according to the scheduling-related information; and performing a Fourier Transform on a transmission information symbol stream by at least one Fourier Transform block based on the resource allocation information, loading the Fourier Transformed transmission information symbol stream on sub-carriers indicated by the resource allocation information, and then transmitting the loaded transmission information symbol stream to the Node B, wherein the power information includes a power headroom information which indicates a difference between a maximum transmission power of the UE and a transmission power used at a time of reporting the power information to the Node B.
