Heuristic radio resource management for massive mimo in satellite broadband communication networks

Abstract

Beam pointing directions and resource mappings are determined for performing wireless communications between a hub station and a plurality of user terminals. For at least one user terminal, a set of candidate beam pointing directions among a predefined set of beam pointing directions is determined such that the candidate beam pointing directions differ from a direction pointing towards the at least one user terminal by less than a predefined amount. For each of the candidate beam pointing directions, a quantity is determined that is positively correlated with an aggregated interference that a beam pointing in the respective candidate beam pointing direction would either cause for the remaining user terminals or receive from the remaining user terminals among the plurality of user terminals, and for serving the at least one user terminal, a candidate beam pointing direction is selected among the set of candidate beam pointing directions that minimizes said quantity.
