The next-generation of mobile communications (5G) will be dominated by the so-called machine-type communications (MTC), which are characterized by the generation, exchange and processing of data stemming from smart machines, without or with low human intervention. For this networks, two new modes of operation are expected, Ultra-Reliable Low Latency Communications (URLLC) and Massive Machine-to-Machine Communications (MM2M). In these new modes, the communication must support small-packet transmissions, which effectively correspond to the traffic generated by MTC. However, for the analysis of communication systems, it is traditionally assumed that the transmissions in the Shannon channel capacity can be achieved through channel coding, which results in a rather accurate model since the blocklength of the channel code is considered to tend to infinity. However, this consideration is no longer valid for URLLC mode. Therefore, the analysis of finite blocklength coding in combination with the fading effects of wireless communication channels, in order to establish URLLC, is of crucial importance for the development of 5G.In this context, this project contributes to the performance analysis of wireless communication systems that exploit the URLLC mode. In particular, the use of cooperative techniques based on relays will be evaluated, which, in addition to achieving significant gains in terms of capacity and coverage, are shown to be more efficient in the finite blocklength regime. Specifically, the present project considers scenarios with amplified-and-forward relays with the existence of direct links, multiple antennas or multiple relays. (AU)
