Abstract(in English) | In recent years, a new type repeater called IRS (Intelligent Reflecting Surface) that can reconfigure the propagation path by controlling the reflection direction and amplitude of the incident electromagnetic wave has been studied. So far, we have proposed a technique that can actively suppress inter-cell interference power by using multiple IRS repeaters in combination. However, the computational complexity for the optimum combination of repeaters increases exponentially as the number of repeaters increases. Therefore, in this paper, we formulated the combination of repeaters as a 0-1 integer programming problem, and used a general-purpose solver to find a combination that maximizes the transmission capacity to the desired wireless station while suppressing the inter-cell interference amount below a certain value. In addition, we proposed a method for clustering by selecting repeaters with similar characteristics and using only their representative values as combination search candidates in order to significantly reduce the computational complexity. As a result of evaluation by computer simulation, the proposed method was more effective in improving the capacity when the number of clusters is smaller than the conventional method, and especially the worst value was improved. |
