Metrics and Methods for Evaluation of Over-The-Air Performance of MIMO User Equipment
Commercial User Equipment (UE) testing and certification has become more complex for state-of-the-art mobile communication standards such as 3rd Generation Partnership Project (3GPP) Long-Term Evolution (LTE) due to the extensive use of Multiple Input-Multiple Output (MIMO) transmission techniques....

| description | Commercial User Equipment (UE) testing
and certification has become more complex for state-of-the-art mobile communication standards such as 3rd
Generation Partnership Project (3GPP) Long-Term Evolution
(LTE) due to the extensive use of Multiple Input-Multiple Output (MIMO) transmission techniques. The
variety of different MIMO operating modes and the almost
unlimited choice of possible multipath channel conditions
under which UE performance may be evaluated are not
accounted for by established Single Input-Single Output
(SISO) Over-The-Air (OTA) performance metrics like
Total Isotropic Sensitivity (TIS) and Total Radiated Power
(TRP). As pointed out in this contribution, meaningful
metrics and cost-effective, low-complexity measurement
methods can, nevertheless, be derived by focusing on
characterization of the physical attributes of UE and by
adopting statistical metrics. Starting from a brief review of
the most important MIMO operating modes in the 3GPP
LTE standard, the relation between UE properties and UE
performance, which is observed in these operating modes, is
discussed. Two complementary metrics and corresponding
measurement procedures for evaluation of MIMO OTA
performance are presented in order to address the diversity
of possible propagation scenarios. Measurement results
from preliminary implementations of the two proposed
measurement procedures, including comparison between
different LTE devices, are presented. |
