Non\u2010orthogonal multiple access (NOMA) has been identified as one of the promising enabling radio access techniques to solve this problem. The basic principle of NOMA is the ability to serve multiple users in the same time and frequency resources but differentiated by their power domains. However, the inherent power\u2010domain multiplexing requires channel gain disparity between the strong and weak users, thereby reducing the sum\u2010rate gain of the network. In this paper, we propose NOMA scheme, integrated with carrier aggregation (CA) to further increase the bandwidth and data rate of users. Simulation results show considerable improvement in terms of throughput, energy efficiency, and fairness among users.<\/jats:p>","DOI":"10.1002\/dac.4701","type":"journal-article","created":{"date-parts":[[2020,12,21]],"date-time":"2020-12-21T01:20:10Z","timestamp":1608513610000},"update-policy":"https:\/\/2.zoppoz.workers.dev:443\/https\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Carrier aggregation\u2010enabled non\u2010orthogonal multiple access approach towards enhanced network performance in 5G Ultra\u2010Dense Networks"],"prefix":"10.1002","volume":"34","author":[{"given":"Oladele","family":"Afolalu","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering University of Cape Town  Cape Town South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neco","family":"Ventura","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering University of Cape Town  Cape Town South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,12,20]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2018.2835558"},{"key":"e_1_2_7_3_1","doi-asserted-by":"crossref","unstructured":"LuK WuZ ShaoX.A Survey of non\u2010orthogonal multiple access for 5G.
