Abstract:
Frequency bands above 6 GHz are expected to be a promising solution for supporting the continued growth in the amount of mobile cellular traffic, although such bands are currently unutilized in mobile communication systems due to their short transmission range. Therefore, low-and high-frequency bands are effectively combined by enhancing the capacity in high-frequency bands while supporting the large coverage in low-frequency bands, which is utilized in the current system. This paper investigates the joint optimization of user association and resource allocation by employing inter-cell interference coordination (ICIC) for multiple frequency bands. This joint optimization problem was viewed as a utility maximization problem based on proportional fair criteria, and an iterative algorithm is proposed to obtain the optimum solution to this problem. We evaluate the performance of the proposed algorithm in multi-cell deployments and demonstrate that the proposed algorithm works well.
