Due to the requirement of high spectrum efficiency, the frequency reuse of one is targeted for next generation OFDMA-based cellular networks. Such a frequency planning strategy can lead to unacceptable inter-cell interference levels experienced especially by users located at the cell edge area. Soft frequency reuse (SFR) is considered as an effective(More)
In this paper, we introduce the application of CR-based spectrum sharing concepts to enable opportunistic relaying operations in cellular networks. In particular, (i) we build on recent FCC rules and CEPT plans (SE43) that regulate the opportunistic spectrum usage in TV white spaces at 470-790 MHz; and (ii) we show that opportunistic relaying can lead to(More)
Historically, mm-wave (mmW) communications have been used for point-to-point (P-P) terrestrial and satellite links, and more recently for indoor short-distance communications. New network architectures consisting of interwoven networks will be needed to meet the requirements of 5G, particularly an ever increasing demand for high data rates. It is believed(More)
Historical fragmentation in spectrum access models accentuates the need for novel concepts that allow for efficient sharing of already available but underutilized spectrum. The emerging Licensed Shared Access (LSA) regulatory framework is expected to enable more advanced spectrum sharing between a limited number of users while guaranteeing their much needed(More)
Regulators around the world are currently setting rules and requirements that will allow for mass-market access to TV White Spaces. It is expected that the opening of those frequency bands to the consumer market will lead to a dramatic increase of spectrum exploitation efficiency in highly appealing frequency bands: In Europe, the frequency bands between(More)
A distributed antenna system (DAS) architecture is considered to be a key enabler for further Network Virtualization where different network configurations are created as needed by a centralized decision making unit that is typically integrated into the Cloud Radio Access Networks (C-RAN) which offers a potential architecture for 5G wireless communication(More)
The next revision of the R&TTE Directive, which represents the basic regulatory framework for wireless communication in Europe, is expected to be finalized in 2011. In particular, this new revision is expected to provide a novel framework for reconfigurable radio devices, for example building on Software Defined Radio features. Those devices may(More)
In this paper, we have proposed the combination of a centralized & decentralized database and distributed spectrum sensing method for secondary spectrum access. The potential benefits of the proposed solution in a cellular scenario exploiting the TV White Space for opportunistic spectrum access have been outlined.
