Abstract
Node-B transmits a power profile of each frequency of transmission data as a step function to a UE. Each UE measures the amount of interference of a received signal, evaluates SINR over the entire frequency band with the power of the received signal, and transmits the evaluation result to Node-B. Node-B evaluates the interference profile in Node-B from the information about the SINR transmitted from the UE and the power of the transmission signal, and determines the frequency profile of the power of the signal transmitted to the UE.
