Abstract	It is of interest for future mobile communication systems that mobile relay nodes (MRNs), i.e., relays mounted on top of transportation vehicles, are deployed in order to improve the system performance. A multi-MRN aided multiuser system is considered in this paper. The performance of the direct transmission mode and the MRN assisted transmission mode under different vehicle penetration loss (VPL) are compared. The users are separated into two categories in which the direct transmission mode and the MRN assisted transmission mode are selected to employ, respectively. A novel power allocation algorithm is proposed to improve the average system capacity under the constraint of total transmit power. The different power allocation schemes are applied for users in two categories to improve the system performance. It is demonstrated by simulation results that the proposed algorithm outperforms the average power allocation algorithm.
