Abstract:

In this paper we propose a new low power resource management for Low Earth Orbit (LEO) satellite communication system with a hybrid multi-beamforming. LEO satellite communication systems are known to have a serious mobility management problem, resulting in inefficient radio resources management and extra power consumption. Joint time/frequency/space resources allocation requires a lot of computational resources to serve thousands of active users. Data traffic suffers from a huge amount of service data, caused by multiple time-frequency resources reallocation. The Earth’s footprint has a curved ellipse shape, which also requires extra computations to calculate the user time location inside a single beam. By utilizing hybrid beamforming structure of the system, we propose a low power resource allocation scheme with a minimal control channel traffic.
