In this scenario, most users experience significant interference levels from neighbouring mobile stations (MSs) and access points (APs) making the use of advanced interference management techniques mandatory. Clustered interference alignment (IA) has been widely proposed to manage the interference in densely deployed scenarios with a large number of users. Nonetheless, the setups considered in previous works are still far from the densification levels envisaged for 5G\/B5G networks that are considered in this paper. Moreover, prior designs of clustered\u2010IA systems relied on oversimplified channel models and\/or enforced single\u2010stream transmission. In this paper, we explore an ultradense deployment of small cells (SCs) to provide coverage in 5G\/B5G wireless networks. A novel cluster design based on a size\u2010restricted <jats:italic>k<\/jats:italic>\u2010means algorithm to divide the SCs into different clusters is proposed taking into account path loss and shadowing effects, thus providing a more realistic solution than those available in the current literature. Unlike previous works, this clustering method can also cater for spatial multiplexing scenarios. Also, several design parameters such as the number of transmit antennas, multiplexed data streams, and deployed APs are analyzed in order to identify trade\u2010offs between performance and complexity. The relationship between density of network elements per area unit and performance is investigated, thus allowing to illustrate that there is an optimal coverage area value over which the network resources should be distributed. Moreover, it is shown that the spectral\u2010efficiency degradation due to the intercluster interference in ultradense networks (UDNs) points to the need of designing an interference management algorithm that accounts for both intracluster and intercluster interferences. Simulation results provide key insights for the deployment of small cells in interference\u2010limited dense scenarios.<\/jats:p>","DOI":"10.1155\/2021\/9914456","type":"journal-article","created":{"date-parts":[[2021,8,1]],"date-time":"2021-08-01T12:20:21Z","timestamp":1627820421000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Deployment of Clustered\u2010Based Small Cells in Interference\u2010Limited Dense Scenarios: Analysis, Design, and Trade\u2010Offs"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9179-7120","authenticated-orcid":false,"given":"David Alejandro","family":"Urquiza Villalonga","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7080-3173","authenticated-orcid":false,"given":"Felip","family":"Riera-Palou","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8346-8140","authenticated-orcid":false,"given":"M.
