Intensive development of standardization in the field of virtualization of network functions, and at the same time the initial stage of standardization of NOMA solutions as part of 3GPP (3rd Generation Partnership Project), in conjunction with the rapidly growing market needs in the Internet of Things domain, creates a real opportunity to use the previously unavailable potential computing in the cloud (MEC, FOG) and at the same time causes a complete change in the approach to effective network management and constitutes a serious research challenge.

The project concerns important aspects of inter-layer 5G resource management for innovation in the physical layer (NOMA, mMIMO-NOMA), which is an essential element of the 5G system enabling the implementation of mass communication (at the level of tens / hundreds of thousands of devices in a cell) in accordance with the MTC paradigm and Internet of Things (IoT) devices support. The immediate motivation to implement the project is the need to provide effective solutions enabling the implementation of NOMA / MIMO-NOMA techniques, also in millimeter wave bands, allowing for implementation also in devices with limited resources (computing power, energy, communication).

The project was financed by the National Center for Research and Development Poland in terms of support joint research projects between Polish and South African researchers based on the Poland NCBR/South Africa NRF joint science and technology research collaboration with grant number

PL-RPA2/02/RATfor5G+/2019 

The project was implemented from January 1, 2019 to June 30, 2022 with a budget of PLN 421,000

Major project tasks

Task 1: Development of a set of inter-layer techniques cooperating with NOMA in IoT networks.

Task 2: Development of RRM techniques for IoT / NOMA networks, ensuring allocation of radio resources enabling simultaneous fulfillment of QoS requirements in combination with optimization of energy consumption and coverage.

Task 3: Prototyping, evaluation and demonstration of selected inter-layer and RRM techniques dedicated to NOMA / mMIMO / mmWAVE in the IoT scenario.

Task 1: Development of refractory and energy efficient radio channel estimation techniques that use spatial spread of channels in MIMO multi-antenna systems in conjunction with NOMA (Massive MIMO-NOMA) techniques.

Task 2: Development of optimal and reliable channel estimation techniques that will avoid the overhead of using training sequences in mass multi-antenna MIMO systems using millimeter waves.

Task 3: Developing user detection techniques with reduced computational complexity that will allow to take advantage of occasional user activity in 5G networks based on NOMA solutions.
