This 3-year research project is focused on LSA by LTE services, which aims at facilitating efficient use of underutilized or unused spectrum shared by incumbents in a manner that all the authorized users can provide LTE services with certain desirable QoS. Emphases are on enabling technologies of dynamic spectrum sensing, sensing-based transmission and access, spectrum availability repository and operation models and mechanism design. Objectives of the 3-year research are as follows: O1) to investigate DSS operation models, analyze sharing strategies of spectrum and radio access network, and develop decision tools for LSA by LTE services; O2) to develop advanced spectrum sensing techniques and dynamically update spectrum map as an informational cornerstone of efficient control and management of next-generation sharing-based spectrum access; O3) to design enabling dynamic spectrum sensing-based transmission and access technologies for LSA by LTE services; and O4) to implement and test the technologies and designs above by exploiting self-developed USRP platform, and LTE small cell and EPC experiment platforms developed by III and/or ITRI. The research team will address the question of appropriate mix of technologies, sharing architectures, operation models, and associated regulatory policies. Achievements of these objectives will allow the research team to V1) help our ICT industry to grasp technology, system and service developments of LSA by LTE services as close followers of the trends, which is complementary to III and CSISTs’ research and developments on spectrum sharing technologies and systems ( for speeding up broadband mobile service deployments; V2) provide scientific and technological support and recommendations to both LTE service operators and regulator regarding LSA by LTE services, and V3) contribute to developing foresights about spectrum sharing technology and operation model developments in 5G mobile broadband system.授權分享接取LTE服務運作模型動態感知頻譜圖傳輸及接取技術共享策略規管政策實驗平台Licensed Shared Access (LSA)LTE servicesoperation modelsdynamic sensingspectrum maptransmission and access technologiessharing strategiesregulation policyexperiment platform
