 Abstract

Mobile voice service is already considered a necessity by many, and mobile data, video, and TV services are now becoming an essential part of consumers' lives. The number of mobile subscribers is growing rapidly and bandwidth demand due to data and video services is increasing. There is a need for capacity to increase in order for mobile broadband, data access, and video services to engage the end consumer. Device-to-device (D2D) communications underlaying cellular networks entails the ability of a cellular network to allow devices to communicate directly with each other in the operating (licensed) spectrum of the cellular network. With the application of specific rules and strategies, D2D communications offloads the mobile network and increases the spectral efficiency. In this thesis we developed a method for the application of D2D communication, controlled by a cellular network. By deriving the theoretical upper bound on the interference we have analytically derived equations describing the minimum distances to be maintained between simultaneously operating links, to achieve a given minimum SINR. We devised a strategy to group and schedule links which fulfill these minimum requirements, so that multiple links may operate simultaneously. We describe a power optimization method to minimize the number of groups to further improve the efficiency of the occupation of resources. Finally we performed simulations for various D2D scenarios, including a scenario representing a realistic urban environment, to illustrate the potential of this grouping and scheduling strategy.
