A Multi-Service Oriented Multiple Access Scheme for M2M Support in Future LTE
IEEE Communications Magazine, 2017Co-Authors: Nassar Ksairi, Stefano Tomasin, Merouane DebbahAbstract:We propose a novel multiple access technique to overcome the shortcomings of the current proposals for the future releases of LTE. We provide a unified radio access system that efficiently and flexibly integrates both traditional cellular services and M2M connections arising from IoT applications. The proposed solution, referred to as MOMA, is based on establishing separate classes of users using relevant criteria that go beyond the simple handheld-IoT device split; service-dependent hierarchical Spreading of the data Signals; and a mix of multiuser and single-user detection schemes at the receiver. Signal Spreading in MOMA allows densely connected devices with different QoS profiles to be handled, and at the same time its flexible receiver structure allows the receiver computational resources to be allocated to the connections that need them most. This yields scalable and efficient use of the available radio resources and better service integration. While providing significant advantages for key future communications scenarios, MOMA can be incorporated into LTE with a limited impact on the protocol structure and the Signaling overhead.

a multi service oriented multiple access scheme for m2m support in future lte
arXiv: Information Theory, 2016Co-Authors: Nassar Ksairi, Stefano Tomasin, Merouane DebbahAbstract:We propose a novel multiple-access technique to overcome the shortcomings of the current proposals for the future releases of Long-Term Evolution (LTE). We provide a unified radio access system that efficiently and flexibly integrates both traditional cellular services and machine-to-machine (M2M) connections arising from Internet-of-Things (IoT) applications. The proposed solution, referred to as multi-service oriented multiple access (MOMA), is based on a) establishing separate classes of users using relevant criteria that go beyond the simple handheld-IoT device split, b) service-dependent hierarchical Spreading of the data Signals and c) a mix of multiuser and single-user detection schemes at the receiver. Signal Spreading in MOMA allows to handle densely connected devices with different quality-of-service (QoS) profiles and at the same time its flexible receiver structure allows to allocate the receiver computational resources to the connections that need it most. This yields a scalable and efficient use of the available radio resources and a better service integration. While providing significant advantages for key future communications scenarios, MOMA can be incorporated into LTE with a limited impact on the protocol structure and the Signaling overhead.

From top to bottom: Cell polarity in Hedgehog and Wnt trafficking
BMC Biology, 2018Co-Authors: Ana-citlali Gradilla, David Sanchez-hernandez, Lucy Brunt, Steffen ScholppAbstract:Spatial organization of membrane domains within cells and cells within tissues is key to the development of organisms and the maintenance of adult tissue. Cell polarization is crucial for correct cell–cell Signalling, which, in turn, promotes cell differentiation and tissue patterning. However, the mechanisms linking internal cell polarity to intercellular Signalling are just beginning to be unravelled. The Hedgehog (Hh) and Wnt pathways are major directors of development and their malfunction can cause severe disorders like cancer. Here we discuss parallel advances into understanding the mechanism of Hedgehog and Wnt Signal dissemination and reception. We hypothesize that cell polarization of the Signal-sending and Signal-receiving cells is crucial for proper Signal Spreading and activation of the pathway and, thus, fundamental for development of multicellular organisms.
