BASE STATION AND STORAGE MEDIUM

According to one embodiment, a base station includes a communication circuit and a controller. The communication circuit receives and transmits uplink data and downlink data. The controller calculates a downlink remaining time based on a first time when the communication circuit receives a resource allocation request, a second time when the communication circuit receives the uplink data, a third time when the communication circuit receives the downlink data, and a round-trip delay threshold time, and determines a fourth time when the communication circuit will transmit the downlink data to the terminal based on the downlink remaining time.
