Critical services in 5G networks, denoted by Ultra-Reliable Low-Latency Communication (URLLC), allow the existence of many promising applications such as factory automation, remote surgery and autonomous vehicles. However, URLLC has unprecedented stringent requirements in terms of reliability and latency, on the order of 99,999% and 1ms, respectively.
One of the most important aspects of URLLC transport is the time-frequency trade-off, where restrictions in the time domain require a large frequency bandwidth to guarantee the target reliability. Using licensed spectrum, as in previous generations, entails a huge cost for operators who buy, at very high price, the license to use certain channels. The cost and scarcity of licensed spectrum calls then for the usage of unlicensed spectrum that is cheaper and available at higher quantities.
In this thesis, we study the transport of critical services over unlicensed spectrum. We design new medium access schemes for URLLC to meet its requirements, by using additional licensed resources or by increasing the transmission power of URLLC while competing with other services.
