LEO Small-Satellite Constellations for 5G and Beyond-5G Communications
Israel Leyva-Mayorga, Beatriz Soret, Maik Röper +4
The next frontier towards truly ubiquitous connectivity is the use of Low Earth Orbit (LEO) small-satellite constellations to support 5G and Beyond-5G (B5G) networks. Besides enhan…
Latency and timeliness in multi-hop satellite networks
Beatriz Soret, Sucheta Ravikanti, Petar Popovski
The classical definition of network delay has been recently augmented by the concept of information timeliness, or Age of Information (AoI). We analyze the network delay and the Ao…
Massive MIMO for Internet of Things (IoT) Connectivity
Alexandru-Sabin Bana, Elisabeth de Carvalho, Beatriz Soret +4
Massive MIMO is considered to be one of the key technologies in the emerging 5G systems, but also a concept applicable to other wireless systems. Exploiting the large number of deg…
Inter-plane satellite matching in dense LEO constellations
Beatriz Soret, Israel Leyva-Mayorga, Petar Popovski
Dense constellations of Low Earth Orbit (LEO) small satellites are envisioned to make extensive use of the inter-satellite link (ISL). Within the same orbital plane, the inter-sate…
A queueing approach to the latency of decoupled UL/DL with flexible TDD and asymmetric services
B. Soret, P. Popovski, K. Stern
One of the main novelties in 5G is the flexible Time Division Duplex (TDD) frame, which allows adaptation to the latency requirements. However, this flexibility is not sufficient t…
Massive Random Access with Common Alarm Messages
Kristoffer Stern, Anders E. Kalør, Beatriz Soret +1
The established view on massive IoT access is that the IoT devices are activated randomly and independently. This is a basic premise also in the recent information-theoretic treatm…
