Abstract:
1. A method for allocating frequency resources to each micro User Equipment (UE) at a micro Base Station (BS) in mobile communication system of a hierarchical cell structure, the method comprising: acquiring information about traffic of each macro UE or a macro BS in a frequency resource allocated to the each macro UE or the macro BS, first Signal-to-Noise Ratio (SNR) information about an SNR of a signal from the each macro UE or the macro BS, measured at each micro UE and second SNR information about an SNR of a signal from the each micro UE, measured at the micro BS; calculating throughput of the each micro UE using the traffic information, the first SNR information and the second SNR information; determining a frequency resource to be allocated to the each micro UE using information about the calculated throughput; and allocating the determined frequency resource to the each micro UE.
