摘要

PROBLEM TO BE SOLVED: To provide a wireless communication system capable of precoding matrix calculation even if the function of a physical layer is distributed, in a system configuration of Partial Centralization, and to provide a central station device, a distribution station device, a communication method of a central station device, and a communication method of a distribution station device.SOLUTION: In addition to the data of modulation symbol required for precoding matrix calculation and DCI corresponding thereto, a precoding matrix generated by MAC function or a matrix dividing the precoding matrix or a vector is sent between a central station device and distribution station device.SELECTED DRAWING: Figure 7
