The goal of this paper is to identify primary (licensed) users when the secondary (non-licensed) system is transmitting without Quiet Period in the same frequency band. The paper further presents the LTE operating in TV channels, where DVB-T and PMSE transmitters are considered as primary users by default. In this context, the LTE system is acting as a… (More)
Opportunistic Networks are temporary, localized, operator-governed network segments that are created under certain circumstances. Opportunistic Networks can be used as coordinated extensions of the infrastructure in order to provide solution to matters such as coverage and capacity extension, infrastructure supported opportunistic ad-hoc networking, traffic… (More)

—The goal of this paper is to present advances on recent 3GPP standardization activities related to Device-to-Device (D2D) and public safety. The paper provides a clear 3GPP state of the art, including when the 3GPP work on D2D and public safety communications started. Finally, it presents important conclusions with respect to further 3GPP work on this… (More)
This paper proposes a novel architecture and configuration scheme for single-node spectrum sensing. It is assumed that the sensing node may use more than one sensing algorithms. The proposed sensing architecture allows a dynamic algorithm selection that depends on the sensing configuration parameters, and it includes a regulatory conformance checking. As a… (More)
