Abstract
In massive MIMO systems the uplink pilot signals
transmitted by a terminal define the channel seen by the base
station. This gives the terminal some degree of freedom selecting
an uplink pilot transmission strategy. In this paper, we investigate
the benefit of different pilot transmission strategies when increasing
the number of antennas in the terminal. Building on previous
work on a simulation framework for Multiple-antenna terminals
in 5G massive MIMO systems, this paper presents simulated
performance results for various transmission schemes. The results
are calibrated to reflect a real communication situation in a large
auditorium. Emulating the measurement set-up, we show that the

In massive MIMO systems the uplink pilot signals

in 5G massive MIMO systems, this paper presents simulated
performance results for various transmission schemes. The results
are calibrated to reflect a real communication situation in a large
auditorium. Emulating the measurement set-up, we show that the
framework can be tuned to generate channel distributions that
match measured data. Under generalized conditions, we perform
simulations for different terminal transmission-strategies, both
related to single stream and multiple streams. All evaluations are
based on terminals with four antennas integrated into real Sony
Xperia smartphone-chassis, tuned to 3.7 GHz. The measurements
are conducted by using the Lund University Massive MIMO
testbed with its 100 antennas. The results clearly show the
advantage of increasing the antenna-count also at the terminal
side in massive MIMO systems. (Less)
