Dynamic Resource Allocation for LEO Satellite Systems Under Heterogeneous Traffic Distributions

International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 199-209, March/April 2026.
ABSTRACT This paper proposes an efficient resource allocation scheme for low Earth orbit (LEO) satellite systems. Taking into account the unique characteristics of LEO systems for 6G communication services, we introduce a dynamic bandwidth and power allocation scheme specifically designed to accommodate highly heterogeneous traffic distributions.

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

5G new radio multiuser precoding in geostationary satellite networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 60-72, January/February 2026.
This work evaluates the standardized 5G new radio codebooks for closed‐loop multiuser precoding in GEO multibeam scenarios and derives a list of recommended 3GPP standard modifications for a proper support to GEO mission needs. Summary The multiuser precoding procedures standardized by the 3rd Generation Partnership Project (3GPP) for new radio (NR ...
