Abstract
This paper presents the results from a live field trial
of the new Licensed Shared Access (LSA) concept using a
TD-LTE network in the 2.3 GHz spectrum band in Finland.
In the trial a live LTE network shares the spectrum from
incumbent programme making and special events (PMSE)
service including cordless cameras without causing
harmful interference. The trial implements the new LSA
concept and the required new building blocks including
LSA Repository for spectrum availability information and
LSA Controller for commanding the mobile communication
network in the band. The trial uses a real TD-LTE base
station, real network management system, and real core
network. Incumbent spectrum usage data is collected to
the LSA Repository and used by the LSA Controller to
retrieve available spectrum bands. LSA Controller uses
the network management system to configure the base
station according to the spectrum availability
information. Incumbent spectrum users' rights are
protected by evacuating the LSA band and handing users
over from the LTE network to other networks when
requested by the incumbent spectrum user. Numerical
results are presented to quantify the duration of the LSA
band evacuation process. The demonstration shows that the
new LSA concept can be implemented with existing network
elements and a minimum amount of new components. The
first performance results on the LSA band evacuation
times indicate that the LSA band can be evacuated and
released in good time and the incumbents' rights can be
protected
