With the increasing number of IoT devices, transmission collisions and hidden\/exposed terminal problems on the Wi-Fi connection side become more and more serious. Conventional mechanisms cannot solve these problems well. In this paper, we propose a Wi-Fi sector (Wi-FiS) design, which is compatible with Wi-Fi, to solve them fundamentally. Wi-FiS divides the whole coverage area of Wi-Fi into multiple sectors and utilizes beamforming technology and sector-based scheduling to improve system performance of Wi-Fi dense networks. For a single-cell network, Wi-FiS differentiates uplink and downlink operations and totally excludes collision in downlink. For a multicell network, Wi-FiS can avoid hidden and exposed terminal problems, while enabling parallel transmissions among multiple cells. We then develop a theoretical model to analyze Wi-FiS\u2019s throughput. Extensive simulations verify that our theoretical model is very accurate and Wi-FiS can improve system throughput of Wi-Fi dense networks significantly.<\/jats:p>","DOI":"10.1155\/2020\/6684681","type":"journal-article","created":{"date-parts":[[2020,12,29]],"date-time":"2020-12-29T02:35:15Z","timestamp":1609209315000},"page":"1-18","source":"Crossref","is-referenced-by-count":7,"title":["Enabling Sector Scheduling for 5G-CPE Dense Networks"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0503-1634","authenticated-orcid":true,"given":"Jie","family":"Yang","sequence":"first","affiliation":[{"name":"Faculty of Information Technology, Macau University of Science and Technology, Taipa, Macau 999078, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6172-8650","authenticated-orcid":true,"given":"Li","family":"Feng","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Macau University of Science and Technology, Taipa, Macau 999078, China"}]},{"given":"Tong","family":"Jin","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Macau University of Science and Technology, Taipa, Macau 999078, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7355-2365","authenticated-orcid":true,"given":"Hong","family":"Liang","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Macau University of Science and Technology, Taipa, Macau 999078, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3312-374X","authenticated-orcid":true,"given":"Fangxin","family":"Xu","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Macau University of Science and Technology, Taipa, Macau 999078, China"}]},{"given":"Liwei","family":"Tian","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Macau University of Science and Technology, Taipa, Macau 999078, China"}]}],"member":"311","reference":[{"key":"1","unstructured":"International Telecommunications Union Radio Communication Sector (ITU-R)Minimum requirements related to technical performance for IMT-2020 radio interface(s)Report ITU-R M.2410-0 (11\/2017), International Telecommunications Union Radio Communication Sector (ITU-R), Geneva, Switzerland, 2017, https:\/\/www.itu.int\/%20pub\/R-REP-M.2410-2017"},{"article-title":"5G for connected industries and automation white paper","year":"2019","author":"5G Alliance for Connected Industries and Automation (5G ACIA)","key":"2"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2016.2525398"},{"first-page":"25","article-title":"CSMA\/CN: carrier sense multiple access with collision notification","author":"S.
