Main objective is to maximize the utility of each secondary user (SU) making them more energy efficient. Quality of Service (QoS) levels of SUs are guaranteed by max-min fair signal to interference plus noise ratio (SINR) concept while maintaining QoS level of the primary user (PU), thus resulting in reliable operation by reducing the sum interference. Further, the applicability of the proposed novel pricing scheme and the algorithm is discussed with respect to a heterogeneous network with proper power and rate controlling. By reducing the sum power of SUs we explore the survival of cognitive users in a lowered interference threshold imposed by the primary network. The existence and uniqueness of Nash equilibrium and its Pareto efficiency is discussed. A novel power and rate control algorithm with a new pricing scheme is introduced to reach the Nash Equilibrium (NE). By using a common platform for rates and utilities, existing algorithms are compared through numerical analysis.","PeriodicalId":417714,"journal":{"name":"2010 IEEE 72nd Vehicular Technology Conference - Fall","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129548680","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}

The coexistence between SUs and PUs addresses the interference from SUs to PUs, whereas, the coexistence among SUs addresses sharing of identified spectrum opportunity among SUs to achieve efficient spectrum usage. In this study, we first introduce a new parameter named as quality of coexistence (QoC), which is defined as the ratio of quality of SU transmission over the negative interference to PUs. Assuming that a time slot of spectrum opportunity has been found by multiple SUs, we partition this time slot into subslots and allocate time slots and transmit power to multiple SUs to maximize the QoC. This leads to a \"wise\" spectrum usage among SUs and minimized interference to PUs. In this study we assume that the SUs have multiple antennas and employ fixed transmit power control (fixed-TPC). By using the approximation of the approximation to the distribution of weighted sum of chi-square random variable (RV) we develop the analytical model for the time slot allocation among SUs. Results show that both the time slot and transmit power allocation can be optimized for achieving the maximum QoC. In a particular scenario the QoC can be increased by 30%.","PeriodicalId":417714,"journal":{"name":"2010 IEEE 72nd Vehicular Technology Conference - Fall","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130545900","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}
