A method and a system for resource allocation are disclosed in the present invention. The method comprises: a network side, according to a preset interference threshold of neighboring cells, determining a transmission power of a cell user on a unit Resource Block (RB), and then determining to obtain the maximum number of RBs which can be allocated to the cell user according to the transmission power of the cell user on the unit RB; the network side, according to the link quality, the path loss condition and the transmission power of the cell user on the unit RB, obtaining a predicted value of the Signal Interface Noise Ratio (SINR) of the received signal, and then obtaining the current Modulation Code Scheme (MCS) of the cell user according to the predicted value of the SINR; and the network side determining a power control parameter according to the transmission power of the cell user on the unit RB and the current MCS of the cell user. In the present invention, the RB allocation, the power control parameter and the Automatic Modulation Code (AMC) work together to reach the maximum throughput of the system, thus guaranteeing the maximum theoretic spectral efficiency. |
