Document Type and Number:
WIPO Patent Application WO/2024/075317
Kind Code:
A1
Abstract:
[Problem] To stably ensure good communication between a user terminal and a base station even under a condition where degradation in communication quality arises due to a change in the orientation of a mobile body or due to shielding. [Solution] In a wireless communication system in which wireless communication takes place between a user terminal 7 mounted on an automobile V1 as a mobile body capable of moving on a road and an access point 4, the user terminal performs wireless communication with the access point by means of directional communication units 78, 79 that are capable of controlling directionality. In a case where the automobile having the user terminal mounted thereon changes the orientation thereof, for example, in a case of making a right or left turn at an intersection, the user terminal performs control on the directionality of the directional communication unit so as to improve the quality of communication with the access point. Specifically, the user terminal performs control on the directional communication unit so that the width and/or the direction of an area covered by the directional communication unit of the user terminal is caused to change. In addition, the user terminal comprises: a forward directional communication unit 78 that has a forward directionality; and a rearward directional communication unit 79 that has a rearward directionality.
