Multi-Antenna System Design for 3GPP LTE

[ahmedtaha]

Abstract

—Standardization work is nearly complete on long
term evolution (LTE) of the UMTS Terrestrial Radio Access and
Radio Access Network which is aimed for commercial
deployment in 2010. Goals for the evolved system include
support for improved system capacity and coverage, high peak
data rates, low latency, reduced operating costs, multi-antenna
support, flexible bandwidth operations and seamless integration
with existing systems. To reach these goals, a new design for the
air interface including state-of-art multi-antenna technology
needs to be deployed. This paper provides a look at different
multi-antenna schemes for LTE downlink and uplink. The paper
also discusses various Node-B antenna configurations and
summarizes the performance of different multi-antenna schemes

under various scenarios.
