Recently, the mobile communication industry
s moving rapidly toward Long Term Evolution,
or LTE, systems. The leading carriers and ven-
dors are committed to launching LTE service in
he near future; in fact, a number of major oper-
ators such as Verizon have initiated LTE service
already. LTE aims to provide improved service
quality over 3G systems in terms of throughput,
spectral efficiency, latency, and peak data rate,
and the MIMO technique is one of the key
enablers of the LTE system for achieving these
diverse goals. Among several operational modes
of MIMO, multiuser MIMO (MU-MIMO), in
which the base station transmits multiple streams
o multiple users, has received much attention as
a way of achieving improvement in performance.
From the initial release (Rel. 8) to the recent
release (Rel. 10), so called LTE-Advanced, MU-
MIMO techniques have evolved from their pre-
mature form to a more elaborate version. In this
article, we provide an overview of design chal-
enges and the specific solutions for MU-MIMO
systems developed in the LTE-Advanced stan-
dard.
