Abstract: The present invention is designed to improve the efficiency of the use of radio resources in retransmission control in future radio communication systems. A user terminal according to one aspect of the present invention has a receiving section that receives a downlink (DL) signal, and a control section that, when a transport block of the DL signal is divided into a plurality of code blocks, controls transmission of retransmission control information representing an acknowledgment (ACK) or a negative acknowledgment (NACK) for each code block, or representing an ACK or a NACK for each code block group, which groups fewer code blocks than the plurality of code blocks.

Abstract: Outward leg instructing unit provides a first instruction for causing drone to acquire examination data of a facility while flying in the vicinity of the facility. Position information acquiring unit acquires position information of a place of focus specified based on the examination data acquired in accordance with the first instruction. Return leg instructing unit provides, as a second instruction, an instruction for causing drone to acquire a greater amount of examination data than that acquired in accordance with the first instruction with regard to the place of focus indicated by the acquired position information, while flying so as to return on a path flown due to the first instruction. Return leg instructing unit provides as the second instruction an instruction to acquire examination data including image data of a greater number of shots, as compared with shooting performed in accordance with the first instruction.

Abstract: Server apparatus, by controlling flight vehicle, causes flight vehicle to fly to a close range of a power-transmission line, and causes flight vehicle to capture images of the power-transmission line. Flight vehicle includes a positioning apparatus of GPS, and the flight of flight vehicle is controlled based on this measured position. On the other hand, each base station in communication network is provided with a positioning apparatus of GPS. The measured position of base station measured by the positioning apparatus is used to specify the error in position of flight vehicle determined by the positioning apparatus. Server apparatus restricts the flight of flight vehicle if the error in position of flight vehicle, which is determined by the positioning apparatus, that captures images of the power-transmission line is a threshold value or more.

Abstract: Time slot specifying unit reads out facility information of a facility to be inspected (specifically, a base station ID of a base station whose previous inspection day is included in a past predetermined period) from facility information storage unit. Daytime information acquiring unit acquires daytime information at positions at which base stations to be inspected are installed. Time slot specifying unit specifies non-backlight time slots based on the read-out facility information and the acquired daytime information. Operation plan generating unit generates an operation plan of drone in which facilities are shot in the specified non-backlight time slots. Operation plan outputting unit outputs the generated operation plan.
