Utility Fair Optimization of Antenna Tilt Angles in LTE Networks
Bahar Partov, Douglas J. Leith, Senior Member, IEEE, and Rouzbeh Razavi, Senior Member, IEEE
We formulate adaptation of antenna tilt angle as a utility fair optimization task. This optimization problem is nonconvex, but in this paper we show that, under reasonable conditions, it can be reformulated as a convex optimization. Using this insight, we develop a lightweight method for finding the optimal antenna tilt angles, making use of measurements that are already available at base stations, and suited to distributed implementation.
