  Point cloud video is the most popular representation of hologram, which is
the medium to precedent natural content in VR/AR/MR and is expected to be the
next generation video. Point cloud video system provides users immersive
viewing experience with six degrees of freedom and has wide applications in
many fields such as online education, entertainment. To further enhance these
applications, point cloud video streaming is in critical demand. The inherent
challenges lie in the large size by the necessity of recording the
three-dimensional coordinates besides color information, and the associated
high computation complexity of encoding. To this end, this paper proposes a
communication and computation resource allocation scheme for QoE-driven point
cloud video streaming. In particular, we maximize system resource utilization
by selecting different quantities, transmission forms and quality level tiles
to maximize the quality of experience. Extensive simulations are conducted and
the simulation results show the superior performance over the existing schemes
