Abstract--Linear precoding for multiuser multiple input mul-
tiple output (MIMO) cellular systems has generally focused on a
single isolated cell. A crucial tool in algorithm development has
been a downlink/uplink duality. Here we investigate downlink
multiuser communications across multiple cells. Previous work
identified the resulting asynchronous interference as a key issue.
We prove the existence of a downlink/uplink duality requiring
time reversal. This duality is used to develop an effective linear
precoding algorithm for multiuser, multi-cell, MIMO systems.
Simulation results illustrate the importance of accounting for,
