In such a system, a blockage is a cause of a disconnection or a serious degradation of communication. Several techniques to control radio links between base stations have been proposed to avoid these problems. These techniques control radio links by a blockage prediction based on camera images. However, those techniques require an accurate position of the UE with a precision of several tens of centimeters. The existing method requires a particular positioning equipment and a system to notify the UE position to the base station, which makes it difficult to apply in real environments. To solve this problem, we propose the UE positioning method using information only on the base station side. Our proposed method estimates a UE position based on temporal variations in images from a RGB-D camera and the received signal strength indicator by movements of the objects. We evaluated our method by experiments in an outside environment that simulates the actual communication environment. The experiments show that the proposed method can estimate the position of the UE.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"577","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"568","bibliographicIssueDates":{"bibliographicIssueDate":"2022-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"63"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00216265","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"created":"2025-01-19T01:17:00.832685+00:00","id":216373,"links":{}}
