AB  - One of the key technologies of 6G communications relies on large intelligent surfaces (LIS),
which can be viewed as a near-field beamformer that is supportive of extremely high symbol rates
and enables a high level of interference avoidance. This article focuses on LIS systems, analysing
the impact of the use of a whole LIS system or a subset of an antenna array. We analyse an LIS
system associated with a single carrier with frequency domain equalization (SC-FDE), and with
different receiver types of varying complexities. Because it is a function of the number of antennas,
the computational complexity decreases when antenna elements that are closer to the user equipment
are used instead of the whole LIS. Moreover, with a partial LIS, a reduction of energy consumption is
achieved, and mitigation of the interference levels is obtained, allowing a performance very close to
that obtained with the whole LIS system.
