Abstract: An information processing apparatus includes a communication interface and a controller. The communication interface receives, from a sensor container, information indicating an orientation of the sensor container. The controller, based on the information indicating the orientation of the sensor container, calculates a calculated value indicating a remaining amount of contents of the sensor container. The controller determines an estimated value of the remaining amount on the basis of the calculated value. The communication interface transmits the estimated value indicating the remaining amount to an external device. When the calculated value indicating the remaining amount decreases by a first predetermined value or more within a predetermined time period, the controller does not perform the determination of the estimated value on the basis of the calculated value.

Abstract: A mobile communication system is a mobile communication system that performs communication between a base station and a user terminal. When a directivity is formed to transmit a radio signal, the base station transmits a first radio signal including identification information to identify the formed directivity and a reference signal. The user terminal receives the first radio signal and transmits a second radio signal including quality information when receiving the reference signal and the identification information. The base station receives the second radio signal and determines the directivity to be formed based on the identification information and the quality information.
