Such cellular networks will implement a diverse multi-layer model comprising device-to-device networks, macro-cells, and different categories of small cells to assist customers with desired quality-of-service (QoS). This multi-layer model affects several studies that confront utilizing interference management and resource allocation in 5G networks. With the growing need for cellular service and the limited resources to provide it, capably handling network traffic and operation has become a problem of resource distribution. One of the utmost serious problems is to alleviate the jamming in the network in support of having a better QoS. However, although a limited number of review papers have been written on resource distribution, no review papers have been written specifically on 5G resource allocation. Hence, this article analyzes the issue of resource allocation by classifying the various resource allocation schemes in 5G that have been reported in the literature and assessing their ability to enhance service quality. This survey bases its discussion on the metrics that are used to evaluate network performance. After consideration of the current evidence on resource allocation methods in 5G, the review hopes to empower scholars by suggesting future research areas on which to focus.<\/jats:p>","DOI":"10.3390\/s21196588","type":"journal-article","created":{"date-parts":[[2021,10,10]],"date-time":"2021-10-10T21:37:49Z","timestamp":1633901869000},"page":"6588","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":83,"title":["Resource Allocation Schemes for 5G Network: A Systematic Review"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0214-2542","authenticated-orcid":false,"given":"Muhammad Ayoub","family":"Kamal","sequence":"first","affiliation":[{"name":"Malaysian Institute of Information Technology (MIIT), Universiti Kuala Lumpur, Kuala Lumpur 50250, Malaysia"},{"name":"Institute of Business and Management, Karachi 75190, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8461-5106","authenticated-orcid":false,"given":"Hafiz Wahab","family":"Raza","sequence":"additional","affiliation":[{"name":"Malaysian Institute of Information Technology (MIIT), Universiti Kuala Lumpur, Kuala Lumpur 50250, Malaysia"}]},{"given":"Muhammad Mansoor","family":"Alam","sequence":"additional","affiliation":[{"name":"Malaysian Institute of Information Technology (MIIT), Universiti Kuala Lumpur, Kuala Lumpur 50250, Malaysia"},{"name":"Riphah Institute of System Engineering (RISE), Faculty of Computing, Riphah International University, Islamabad 46000, Pakistan"}]},{"given":"Mazliham Mohd","family":"Su\u2019ud","sequence":"additional","affiliation":[{"name":"Malaysian France Institute (MFI), Universiti Kuala Lumpur, Kuala Lumpur 50250, Malaysia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2475-1047","authenticated-orcid":false,"given":"Aznida binti Abu Bakar","family":"Sajak","sequence":"additional","affiliation":[{"name":"Malaysian Institute of Information Technology (MIIT), Universiti Kuala Lumpur, Kuala Lumpur 50250, Malaysia"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102638","DOI":"10.1016\/j.jnca.2020.102638","article-title":"A comprehensive survey on resource allocation for CRAN in 5G and beyond networks","volume":"160","author":"Ejaz","year":"2020","journal-title":"J.
