Cellular networks

The Institute pursues research on contemporary and
future radio access networks, in particular on the
fourth-, fifth- and sixth-generation cellular systems
(4G, 5G and 6G). It concerns new physical-, data-link
control-, medium-access control-, and network-layer
techniques for achieving key performance indicators
(KPI) stated for 4G, 5G and 6G. New solutions, includ-
ing non-orthogonal multiple access (NOMA) using
diverse power allocation, and space-division multiple
access (SDMA) using adaptive antennas, are investi-
gated. Moreover, effective algorithms for radio-
resource management in cells of various types, and for
interference coordination in pico- and femto-cells are
also the subjects of research.
An important direction of research is efficient duplex transmission in relay links, as well as flexible selec-
tion of relaying nodes for quality-of-service improvement in cellular networks. The investigated topic
related to specific challenging applications is ultra-reliable low latency communication (URLLC), one of
the main segments of 5G systems.
