论文摘要
本文考虑了共享相同频谱的设备对设备(D2D)通信中的资源分配问题。特别是,CUS使用非正交的多重访问(NOMA),而DUS采用正交频分多访问(OFDMA)。制定了多目标优化问题(MOOP),该问题共同提高了上行链路通信中D2D和CUS(CUS)的总和率,同时考虑到D2D和CUS的最大传输功率预算以及最低数据速率要求。该摩托车由加权Tchebycheff方法处理,该方法将其转换为单目标优化(SOOP)。然后,采用单调优化方法来最佳地解决该SOOP。数值结果揭示了D2D和CUS之间一个有趣的权衡。
This paper considers a resource allocation problem in device-to-device (D2D) communications sharing the same frequency spectrum. In particular, the CUs utilize non-orthogonal multiple access (NOMA) while DUs adopt the orthogonal frequency division multiple access (OFDMA). A multi-objective optimization problem (MOOP) is formulated, which jointly maximizes the sum rate of D2D and CUs (CUs) in uplink communications while taking into account the maximum transmit power budget and minimum data rate requirement for D2D and CUs. This MOOP is handled by the weighted Tchebycheff method, which converts it into a single-objective optimization (SOOP). Then, the monotonic optimization approach is employed to solve this SOOP optimally. Numerical results unveil an interesting tradeoff between D2D and CUs.
