Description: Current wireless networks were developed with the goal of transmitting large data streams: files, webpages, multimedia information. The next generation of wireless networks is facing a new challenge in the form of machine type communication. Indeed, according to Cisco, in 2015 the number of devices involved in network communication exceeded the world population twofold, and this figure continues to grow exponentially. Note, that the traffic generated by devices significantly differs from the traffic generated by human users and mainly consists of short data packets. We can distinguish two main scenarios of machine type communications: 1) massive machine type communication (mMTC) – technology which allows for the interaction of 20,000-50,000 autonomous devices connected to the same access point. This technology is of critical importance for mass deployment of Internet of Things systems; and 2) ultra-reliable and low-latency communication (uRLLC) – technology of short data packet transmission with a delay of at most 1 ms and a probability of packet loss at most 10-5-10-7 for critical applications. Existing wireless networks are inefficient in these scenarios. In this project, we plan to develop new non-orthogonal multiple access schemes for the mMTC scenario and methods for ensuring guaranteed packet delivery for the uRLLC scenario.
