Abstract-- This paper addresses multiuser linear precoding
using multiple cooperating base stations (BSs). All BSs, and
potentially the users, are equipped with multiple antennas. Prior
work in multiuser precoding with a single BS extensively uses
a downlink/uplink duality that significantly reduces the compu-
tation load. Here we show that the presence of asynchronous
