Title: BASE STATION DEVICE, TERMINAL DEVICE AND TRANSMISSION CONTROL METHOD
Abstract:
[Problem] To make it possible to shorten waiting time before a user terminal receives a signal transmitted from a base station in a time-division manner, and further reliably transmit a transmission beam in a direction in which the user terminal is present. [Solution] A small cell base station 1 that transmits a downlink signal shared by a plurality of user terminals 3 located in a cell in a time division manner while changing the direction of a transmission beam is provided with: a wireless communication unit 11 that transmits the downlink signal in a time division manner while changing the direction of the transmission beam; an information storage unit 14 that stores transmission schedule information defining the transmission timing of the transmission beam such that on the basis of history information relating to whether or not the user terminal is located in each of sectors that are arrival areas of the transmission beam in the past, the transmission beam corresponding to the sector in which the frequency with which the user terminal is located is low is thinned out; and a control unit 13 that on the basis of the transmission schedule information, controls the transmission beam when the downlink signal is transmitted.
