Abstract: A multicell joint adaptive resource allocation scheme is proposed for multicell orthogonal frequency division multiplexing (OFDM) systems. In order to reduce the complexity of the system, subchannel allocation and power allocation are performed in different level separately. Subchannels are dynamically allocated in every cell using modified Max C/I algorithm, and then we use tabu search (TS) to find the optimal transmit power allocation on co-channel of multicell base on the results of subchannel allocation. Performance analysis and simulation results show that the proposed scheme can increase system throughput while guarantee the minimum rate request of all users.
