The tilted antenna array can provide the merit of traffic balance and also achieve the optimization of the signal-to-interference ratio (SIR) at receivers by automatically tilting the antenna and implementing the soft boundary among cells, corresponding to the variation of traffic. According to our results, it is shown that power ratio control do not necessarily improved system performance when there is a large variation in traffic because it only control power levels. Also the properly chosen angle of tilt antenna can relieve the traffic congestion and perform the system performance optimization.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6035","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐々木, 重信"}]},{"nameIdentifiers":[{"nameIdentifier":"6036","nameIdentifierScheme":"WEKO"}],"names":[{"name":"菊池, 久和"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Institute of Electronics, Information and Communication Engineers"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/trans_online/","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"copyright©2003 IEICE（許諾番号07RB0183）"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10826239","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168508","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Zhou, Jie"}],"nameIdentifiers":[{"nameIdentifier":"6031","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, Shigenobu"}],"nameIdentifiers":[{"nameIdentifier":"6032","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuchi, Hisakazu"}],"nameIdentifiers":[{"nameIdentifier":"6033","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Onozato, Yoshikuni"}],"nameIdentifiers":[{"nameIdentifier":"6034","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"1_0013.pdf","filesize":[{"value":"687.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1_0013.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1880/files/1_0013.pdf"},"version_id":"8dc41390-39ee-4241-9a71-19d3180599f1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"cellular system","subitem_subject_scheme":"Other"},{"subitem_subject":"reverse","subitem_subject_scheme":"Other"},{"subitem_subject":"forward links","subitem_subject_scheme":"Other"},{"subitem_subject":"traffic balance","subitem_subject_scheme":"Other"},{"subitem_subject":"tilted antenna array","subitem_subject_scheme":"Other"},{"subitem_subject":"power ratio control","subitem_subject_scheme":"Other"},{"subitem_subject":"radiation pattern","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Cell Boundary Shifting with Power Ratio Control and Tilted Antenna Arrays in a Cellular Wireless Communications","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cell Boundary Shifting with Power Ratio Control and Tilted Antenna Arrays in a Cellular Wireless Communications"},{"subitem_title":"Cell Boundary Shifting with Power Ratio Control and Tilted Antenna Arrays in a Cellular Wireless Communications","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-08"},"publish_date":"2008-04-08","publish_status":"0","recid":"1880","relation_version_is_last":true,"title":["Cell Boundary Shifting with Power Ratio Control and Tilted Antenna Arrays in a Cellular Wireless Communications"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:44.455711+00:00"}
