Our aim is to minimize the average energy consumption of the HCN while maintaining the Quality-of-Service (QoS) experienced by MTs. For each cell (i.e., a macrocell or a small-cell), the energy consumption is determined by its system load which is coupled with the system loads served in other cells due to the sharing over a common frequency band. We model the energy-aware traffic offloading in such HCNs as a constrained Markov decision process (C-MDP). The statistics of the C-MDP depends on a selected traffic offloading strategy and thus, the actions performed by a network controller have a long-term impact on the network state evolution. Based on the traffic demand observations and the traffic offloading operations, the controller gradually optimizes the strategy with no prior knowledge of the process statistics. Numerical experiments are conducted to show the effectiveness of the proposed learning framework in balancing the tradeoff between energy saving and QoS satisfaction.","PeriodicalId":288065,"journal":{"name":"2014 1st International Workshop on Cognitive Cellular Systems (CCS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124268772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though spectrum owners, also known as Incumbents, will cooperate with cellular operators in the framework of a Sharing Agreement that is typically set-up for a long-term basis, the LSA concept will in addition, under specific conditions, give Incumbents the opportunity to reclaim spectrum on a per-need basis. Obviously, this new concept for managing spectrum introduces a number of novel challenges, such as vacate in a coordinated manner the LSA bands in case of a corresponding request being triggered by Incumbents, coordinate the LSA spectrum when it is used in proximity to neighbouring countries and/or regulation domains, establish protection zones in which maximum interference levels are guaranteed to Incumbents, etc. This paper gives an overview on the LSA state-of-the-art and elaborates the key challenges to be addressed in the future design of LSA systems.","PeriodicalId":288065,"journal":{"name":"2014 1st International Workshop on Cognitive Cellular Systems (CCS)","volume":"115 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128998811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
