Abstract
Satellites provide connectivity in remote and rural areas as well as providing applications and services elsewhere on earth and in space. Existing satellite networks will be increasingly augmented by ultra-dense deployments of interconnected satellites providing low Earth orbit (LEO) constellations. However, such satellites only offer short-term line-of-sight access requiring ongoing handovers during the duration of a terminal's access. Accordingly, to exploit these LEO constellations the inventors have established methodologies exploiting distributed massive multiple-input multiple-output technology for a user terminal to be connected to a cluster of LEO satellites. Further, distributed joint power allocation and handover management techniques are outlined for improving the power allocation and handover management processes in a cross-layer manner such that enhanced network throughput and reduced handover rate are provided whilst taking into account quality-of-service demands of terminals and the power capabilities of the LEO satellites.
