| Summary: | 碩士 === 國立清華大學 === 資訊工程學系 === 104 === Device-to-device (D2D) communication underlying cellular networks is a promising solution to increase system throughput and to achieve higher spectral efficiency. However, D2D communications may cause serious mutual interference among D2D pairs and cellular users (CUEs) due to D2D pairs and CUEs share the same radio resource. In this paper, we formulate the uplink resource allocation problem and propose a fast resource allocation algorithm called Maximum independent set based and Stackelberg power based (MiSo) algorithm to get good system throughput. In the MiSo algorithm, we exploit both maximum independent set and power control to allow more D2D pairs able to reuse the same resource block, thus improving system throughput. Furthermore, we propose a mechanism that allocates resource blocks (RB) to proper CUEs in the case when the number of CUEs is larger than the number of RBs. Simulation results show that the MiSo algorithm not only is superior in running time, but also has the splendid percentage of permitted DUE pairs and system throughput.
