In this paper, we investigate the Wi-Fi performance in the presence of duty cycle based LTE-U transmission on the same channel. More specifically, one LTE-U cell and one Wi-Fi basic service set (BSS) coexist by allowing LTE-U devices to transmit their signals only in predetermined duty cycles. Wi-Fi stations, on the other hand, simply contend the shared channel using the distributed coordination function (DCF) protocol without cooperation with the LTE-U system or prior knowledge about the duty cycle period or duty cycle of LTE-U transmission. We define the fairness of the above scheme as the difference between Wi-Fi performance loss ratio (considering a defined reference performance) and the LTE-U duty cycle (or function of LTE-U duty cycle). Depending on the interference to noise ratio (INR) being above or below \u221262\u2009dbm, we classify the LTE-U interference as strong or weak and establish mathematical models accordingly. The average throughput and average service time of Wi-Fi are both formulated as functions of Wi-Fi and LTE-U system parameters using probability theory. Lastly, we use the Monte Carlo analysis to demonstrate the fairness of Wi-Fi and LTE-U air time sharing.<\/jats:p>","DOI":"10.1155\/2017\/6486380","type":"journal-article","created":{"date-parts":[[2017,1,15]],"date-time":"2017-01-15T16:04:34Z","timestamp":1484496274000},"page":"1-10","source":"Crossref","is-referenced-by-count":12,"title":["Wi-Fi Coexistence with Duty Cycled LTE-U"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1818-4998","authenticated-orcid":true,"given":"Yimin","family":"Pang","sequence":"first","affiliation":[{"name":"Department of Electrical, Computer and Energy Engineering, University of Colorado Boulder, Boulder, CO 80309, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alireza","family":"Babaei","sequence":"additional","affiliation":[{"name":"Ofinno Technologies, Herndon, VA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Andreoli-Fang","sequence":"additional","affiliation":[{"name":"Cable Television Laboratories, Louisville, CO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Belal","family":"Hamzeh","sequence":"additional","affiliation":[{"name":"Cable Television Laboratories, Louisville, CO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/49.840210"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1002\/wcm.263"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2005.08.006"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2017\/6486380.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2017\/6486380.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2017\/6486380.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,1,15]],"date-time":"2017-01-15T16:04:35Z","timestamp":1484496275000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2017\/6486380\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":3,"alternative-id":["6486380","6486380"],"URL":"https:\/\/doi.org\/10.1155\/2017\/6486380","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"type":"print","value":"1530-8669"},{"type":"electronic","value":"1530-8677"}],"subject":[],"published":{"date-parts":[[2017]]}}}
