Abstract

This letter develops a dynamic point selection strategy for coordinated multipoint transmission using a message-passing approach. The dynamic determination of the best transmit point for individual users with the objective of the sum-rate maximization can be cast as a bipartite b-matching problem, the computational cost of which, however, becomes quickly intractable with the increasing number of users. Therefore, this letter develops a message-passing algorithm that solves this computationally demanding challenge. Simulation results show that the proposed algorithm outperforms existing greedy-style approaches and provides a very efficient solution for the maximal sum-rate configuration.
