Millimeter-wave bands provide sufficient spectral resource and avoid cross-tier interference with existing low-frequency wireless services in a heterogeneous network. However, coordination over millimeter-wave small cells for combating interference, providing line-of-sight links, and improving system efficiency has stringent requirements on synchronizations and backhaul capacity. As a result, current standards and approaches for the coordination of low-frequency cells based on distributed digital processing can barely apply on millimeter-wave small cells. This work theoretically and experimentally explores new directions of inter-cell interference cancellation and coordinated multi-point transmissions for coordination over millimeter-wave small cells. Different from conventional approaches, the millimeter-wave coordination mechanisms studied in this research are inherent from a fiber-wireless architecture that enables optical processing for millimeter-wave generation, distribution, synchronization, and centralized coordination. Based on the supportive results derived from the preliminary study of the mechanisms, we propose the methods of cooperative multiple-input multiple-output and network-wide coordination based on optical processing and fiber-wireless centralization for multi-cell and multi-user coordination over millimeter-wave small cells. The proposed methods utilize centralized resource and local high-capacity fiber links and are expected to provide transparency and global coherency for efficient coordination and seamless integration with future heterogeneous networks.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Centralization and Synchronization of Millimeter-wave Coordinated Multi-point Transmission in Heterogeneous Fiber-wireless Access Networks"}],"uid":"28475","created_gmt":"2017-02-02 20:35:07","changed_gmt":"2017-04-13 21:13:01","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-02-15T15:30:00-05:00","event_time_end":"2017-02-15T17:30:00-05:00","event_time_end_last":"2017-02-15T17:30:00-05:00","gmt_time_start":"2017-02-15 20:30:00","gmt_time_end":"2017-02-15 22:30:00","gmt_time_end_last":"2017-02-15 22:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
