This paper proposes the dynamic resource assignment (DRA) scheme in the multi-carrier mesh-topology millimeter-wave (MMW) broadband entrance networks. In the DRA scheme, the radio path allocation and the frequency channel assignment techniques are deployed to maximize the network throughput. In the radio path allocation technique, the traffic load is distributed into the appropriate paths. On the other hand, the frequency channel assignment is performed based on the linear programming (LP) method. As the results, the proposed DRA scheme yields higher throughput performance than the conventional scheme using the random frequency channel assignment. In addition, the proposed scheme can guarantee the throughput performance when the number of frequency channels is 36 and the input load is no more than 9 Gbps. Moreover, the proposed scheme can yield the satisfaction sub-optimum throughput with the small computational complexity.
