Apparatus and method for efficient resource allocation using cognitive radio communication in orthogonal frequency division multiple access (OFDMA)-based moving networks
An apparatus and a method for efficient resource allocation using a cognitive radio communication in Orthogonal Frequency Division Multiple Access (OFDMA)-based moving networks are provided. The method includes determining a minimum transmit power value of the MRS, which enables the internal terminal to have a receive Signal to Interference and Noise Ratio (SINR) greater than a first threshold; determining a transmit power value of the MRS by taking into account the determined minimum transmit power value; determining a transmit power value of the MRS per cellular terminal, which is transmittable at maximum while exerting interference less than a second threshold on a corresponding cellular terminal; searching one or more cellular terminals having the maximum transmittable transmit power value determined per cellular terminal greater than the determined transmit power value; and borrowing and allocating a resource allocated to the searched cellular terminal to the internal terminal.
