Cellular networksThe 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, including non-orthogonal multiple access (NOMA) using diverse power allocation, and space-division multiple access (SDMA) using adaptive antennas, are investigated. Moreover, effective algorithms for radioresource 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 selection 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.
