文摘The device-to-device(D2D)technology performs explicit communication between the terminal and the base station(BS)terminal,so there is no need to transmit data through the BS system.The establishment of a short-distance D2D communication link can greatly reduce the burden on the BS server.At present,D2D is one of the key technologies in 5G technology and has been studied in depth.D2D communication reuses the resources of cellular users to improve system key parameters like utilization and throughput.However,repeated use of the spectrum and coexistence of cellular users can cause co-channel interference.Aiming at the interference problem under the constraint of fair resource allocation and improving the system throughput,this paper proposes an effective resource optimization scheme based on the firework method.The main idea is to expand the weighted sum rate and convert the allocated resource expression into fireworks to determine the correlation matrix.The simulation results show that,compared with the existing scheme,this scheme improves system performance by reducing interference.

文摘Real-time and high-precision Fifth-generation mobile communication technology(5G)positioning is essential for establishing a wide-area and high-accuracy spatiotemporal reference framework in urban environments.However,a main challenge is the Non-Line-Of-Sight(NLOS)error significantly impact positioning accuracy,limiting the full deployment and application of 5G technology.In this study,a novel NLOS error mitigation method using Virtual Base-Station(VBS)-assisted algorithm is developed to enhance both kinematic and static positioning performance of 5G systems in complex urban environments.The proposed method consists of three modules:(1)a Time-Of-Arrival(TOA)positioning model,(2)a VBS generation method,and(3)a stable-state discrimination method.The TOA positioning model utilizes raw TOA measurements and a conventional four-station localization algorithm to estimate the location of user equipment.The VBS generation method optimizes Base-Station(BS)performance with particle filter combined with a random-distribution algorithm.The stable-state discrimination method employs the Augmented Dickey-Fuller(ADF)test to assess the stationarity of the feedback iteration process in VBS optimization.Several experiments are conducted in diverse scenario areas to evaluate the effectiveness,accuracy,and robustness of the proposed method.The results demonstrate that the proposed method significantly outperforms the traditional localization method,a 21.09%improvement in Three-Dimensional(3D)positioning accuracy.Compared to the state-of-the-art method,the proposed algorithm not only achieves slightly higher accuracy but,more importantly,reduces significantly the computation time.
