Abstract

Recently, the 3rd Generation Partnership Project has developed vehicle-to-everything communication to manage and advance future traffic safety and mobility. In this study, we propose a position-based resource allocation scheme for vehicle-to-vehicle communication. The proposed scheme allocates a different frequency and time resources based on vehicle speed, density, direction, and position. Our performance analysis is based on urban and freeway cases involving periodic message transmission. Simulation results show that the proposed scheme can improve the cumulative distribution function of packet reception ratio (PRR) and average PRR. [ABSTRACT FROM AUTHOR]

Abstract

Recently, the 3rd Generation Partnership Project (3GPP) developed a sidehaul system to cope with rapidly increasing mobile data traffic. However, numerous challenging technical problems remain to be resolved. One of the major problems is interference management between small cells. In this paper, we propose an advanced receiver based on soft decision to reduce the interference from neighboring cells in the sidehaul system. The proposed receiver can suppress and cancel interference by integrating the interference rejection combining technique with successive interference cancellation. The interference signal is updated using soft information expressed by a log-likelihood ratio. We perform a simulation based on the 20-MHz bandwidth of the 3GPP LTE-Advanced technology. Simulation results show that the proposed receiver can achieve a lower error rate and a higher throughput compared to conventional receivers. [ABSTRACT FROM AUTHOR]
