UAV, also known as wireless aerial platforms, can be employed to improve both the network coverage and capacity. In this paper, we integrate small drone cells into a H\u2010CRAN. However, new complications and challenges, including 3D drone deployment, user association, admission control, and power allocation, emerge. In order to address these issues, we formulate the problem by maximizing the network throughput through jointly optimizing UAV 3D positions, user association, admission control, and power allocation in H\u2010CRAN networks. However, the formulated problem is a mixed integer nonlinear problem (MINLP), which is NP\u2010hard. In this regard, we propose an algorithm that combines the genetic convex optimization algorithm (GCOA) and particle swarm optimization (PSO) approach to obtain an accurate solution. Simulation results validate the feasibility of our proposed algorithm, and it outperforms the traditional genetic and K\u2010means algorithms.<\/jats:p>","DOI":"10.1155\/2021\/6668756","type":"journal-article","created":{"date-parts":[[2021,4,25]],"date-time":"2021-04-25T00:35:37Z","timestamp":1619310937000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Concise and Informative Article Title Throughput Maximization through Joint User Association and Power Allocation for a UAV\u2010Integrated H\u2010CRAN"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7097-2863","authenticated-orcid":false,"given":"Yingteng","family":"Ma","sequence":"first","affiliation":[]},{"given":"Haijun","family":"Wang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2642-5512","authenticated-orcid":false,"given":"Jun","family":"Xiong","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6860-9312","authenticated-orcid":false,"given":"Dongtang","family":"Ma","sequence":"additional","affiliation":[]},{"given":"Haitao","family":"Zhao","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,4,24]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2015.2422266"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2016.2598736"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2014.7000980"},{"key":"e_1_2_8_4_2","doi-asserted-by":"crossref","unstructured":"ZhangY.andWangY.
