  • Patent number: 10805905
    Abstract: Information on allocation of a bandwidth of uplink communication of each of user devices is extracted from information notified from an upper-level device on the uplink communication of the user devices. Correspondence information is created to indicate a correspondence among the upper-level device, the terminal device, the lower-level device, and the user device. A start time point of the uplink communication of the terminal device and an information amount of signals for which transmission of the uplink communication of the terminal device is allowed are allocated to the terminal device on the basis of the information on allocation of the bandwidth of the uplink communication of each of the user devices and the correspondence information.
