11. The MISO Interference Channel as a Model for Non-Orthogonal Spectrum Sharing
Abstract : The demand for wireless communications services has increased during the last decades. To meet this demand, there is a need for allocating larger frequency bands. However, most of the frequency bands (or spectrum) suitable for wireless communication are occupied and allocated to licensed systems. READ MORE

12. Sharing The Design Authorship Of Sustainability : Towards co-creation of sustainable transport systems and practices
Abstract : Any separation between technology and society can be claimed to be artificial. Technological material systems are intertwined with human everyday life practices and ways of living, values, and belief systems. When we design and develop new technological systems, we are also designing opportunities for new daily living practices to emerge. READ MORE

13. Radio Resource Sharing in Hierarchical Cellular Systems
Abstract : Hierarchical Cell Structures (HCSs) is generally believed tobe a solution to capacity problems of future mobilecommunication systems. In such systems we have a mix of cellsizes that handle different types of traffic. We can have largecells providing wide area coverage and small cells providinghigh capacity. READ MORE

14. Decentralized Resource Sharing and Associationin in Wireless Networks
Abstract : In wireless networks, some of the most important supporting functionalities are decentralized resource sharing and association of clients to access points. These functionalities aim to optimally allocate the available wireless transmission resources, for example, time or spectrum channels, the transmit power, access points, and relaying opportunities, all of which are subject to availability constraints.

15. On the feasibility of unicensed operation in shared spectrum
Abstract : Whether unlicensed operation is a feasible mode of operationin future infrastructures depends on a number of factors. Herea comparison is made between systems with exclusive licensesand cases where more than one system uses the same radiospectrum. READ MORE
