The new scheme introduces weights that adapt the classical PF metric to the NOMA scenario, improving performance indicators and enabling new services. The distinguishing value of the proposal resides in its ability to improve long\u2010term fairness and total system throughput while achieving a high level of fairness in every scheduling slot. Finally, it is shown that the additional complexity caused by the weight calculation has only a limited impact on the overall scheduler complexity, while simulation results confirm the claimed improvements, making the proposal an appealing alternative for resource allocation in a cellular downlink system.<\/jats:p>","DOI":"10.1155\/2018\/5642765","type":"journal-article","created":{"date-parts":[[2018,5,16]],"date-time":"2018-05-16T23:55:02Z","timestamp":1526514902000},"update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Weighted Proportional Fair Scheduling for Downlink Nonorthogonal Multiple Access"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-4043-7579","authenticated-orcid":false,"given":"Marie-Rita","family":"Hojeij","sequence":"first","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0001-9803-7810","authenticated-orcid":false,"given":"Charbel","family":"Abdel Nour","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0003-4827-8389","authenticated-orcid":false,"given":"Joumana","family":"Farah","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0002-0437-7345","authenticated-orcid":false,"given":"Catherine","family":"Douillard","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2018,5,16]]},"reference":[{"key":"e_1_2_12_1_2","unstructured":"3GPP TS36.300 Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description."},{"key":"e_1_2_12_2_2","unstructured":"3GPP TR36.913 (V8.0.0) 3GPP andTSG RAN Requirements for further advancements for E-UTRA (LTE-Advanced) 2008."},{"key":"e_1_2_12_3_2","unstructured":"3GPP TR36.814 (V9.0.0) Further Advancements for E-UTRA Physical Layer Aspects 2010."},{"key":"e_1_2_12_4_2","unstructured":"Ericsson Mobility Report on the pulse of the networked society https:\/\/www.ericsson.com\/assets\/local\/mobility-report\/documents\/2017\/ericsson-mobility-report-june-2017.pdf June 2017."},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2018.1700845"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2003.813523"},{"key":"e_1_2_12_7_2","doi-asserted-by":"crossref","unstructured":"TakedaT.andHiguchiK.
