In this paper, soft mobility is proposed for UCN with the split of control and user plane (C\/U\u2010plane) and shared physical cell identifier (PCI) to achieve the goal of zero handover failure (HOF) probability, where transparent handover (HO) within a cell is realized with user configuration duplication and measurement enhancement. Specifically, the cell is composed of several SBSs around the user, where one anchor SBS is selected for controlling, and others act as slave SBSs for transmission with duplicated UE configuration from the anchor SBS. Based on the proposed architecture, the user measures downlink channel quality for cells and SBSs distinguishingly, via SS\/PBCH Block (SSB) and channel\u2010state information\u2010reference signal (CSI\u2010RS), respectively, and then makes the HO decision. Results show that soft mobility can reduce the number of HOF by about 50% over the current system, and the HOF probability is lower than 1% for TTT = 40\u2009ms and offset = \u22121\u2009dB.<\/jats:p>","DOI":"10.1155\/2021\/9971565","type":"journal-article","created":{"date-parts":[[2021,7,13]],"date-time":"2021-07-13T23:20:10Z","timestamp":1626218410000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Soft Mobility: Transparent Handover with Zero Handover Failure in User\u2010Centric Networks"],"prefix":"10.1155","volume":"2021","author":[{"given":"Yong","family":"Sun","sequence":"first","affiliation":[]},{"given":"Haoyan","family":"Wei","sequence":"additional","affiliation":[]},{"given":"Shusheng","family":"Wang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2031-5985","authenticated-orcid":false,"given":"Hongtao","family":"Zhang","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,7,13]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.3010896"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2018.2791178"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/LWC.2018.2869804"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/LWC.2018.2873389"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2016.2606420"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2020.3005947"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2019.2958100"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2021.3054680"},{"key":"e_1_2_12_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2020.3024686"},{"key":"e_1_2_12_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2020.2987082"},{"key":"e_1_2_12_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2019.1800039"},{"key":"e_1_2_12_12_2","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2017.1700410"},{"key":"e_1_2_12_13_2","doi-asserted-by":"publisher","DOI":"10.1049\/iet-com.2018.5938"},{"key":"e_1_2_12_14_2","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2017.2771419"},{"key":"e_1_2_12_15_2","doi-asserted-by":"publisher","DOI":"10.1109\/MNET.2018.1700223"},{"key":"e_1_2_12_16_2","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2016.7462488"},{"key":"e_1_2_12_17_2","volume-title":"Technical Specification Group Radio Access Network;
