{"doi":"10.1109/jsac.2014.2328098","title":"What Will 5G Be?","abstract":"What will 5G be? What it will not be is an incremental/nadvance on 4G. The previous four generations of/ncellular technology have each been a major paradigm shift/nthat has broken backwards compatibility. And indeed, 5G will/nneed to be a paradigm shift that includes very high carrier/nfrequencies with massive bandwidths, extreme base station and/ndevice densities and unprecedented numbers of antennas. But/nunlike the previous four generations, it will also be highly/nintegrative: tying any new 5G air interface and spectrum together/nwith LTE and WiFi to provide universal high-rate coverage and/na seamless user experience. To support this, the core network/nwill also have to reach unprecedented levels of flexibility and/nintelligence, spectrum regulation will need to be rethought and/nimproved, and energy and cost efficiencies will become even more/ncritical considerations. This paper discusses all of these topics,/nidentifying key challenges for future research and preliminary/n5G standardization activities, while providing a comprehensive/noverview of the current literature, and in particular of the papers/nappearing in this special issue.","journal":"IEEE Journal on Selected Areas in Communications","year":2014,"id":7106,"datarank":23.282308387735238,"base_score":9.004176840696656,"endowment":9.004176840696656,"self_citation_contribution":1.3506265261044987,"citation_network_contribution":21.93168186163074,"self_endowment_contribution":1.3506265261044987,"citer_contribution":21.93168186163074,"corpus_percentile":95.9,"corpus_rank":1351,"citation_count":8136,"citer_count":195,"citers_with_citation_signal":195,"citers_with_endowment":195,"datacite_reuse_total":0,"is_dataset":false,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2014-06-01","authors":[{"id":64547,"name":"Stefano Buzzi","orcid":"0000-0003-0046-8968","position":1,"is_corresponding":false},{"id":13349,"name":"Wan Choi","orcid":"0000-0003-3930-7088","position":2,"is_corresponding":false},{"id":64548,"name":"Stephen V.
