description

Reliable communication is a fundamental service level agreement criterion in wireless networks. Moreover, it is a performance indicator for ultra- reliable communication (URC) in emerging 5G networks. In URC, the quality of the delivered services to end-users ultimately depends on the availability of network resources as well as the quality of the received signal. Therefore, in order to analyze URC in cellular networks, both time- dependent spectrum availability and space-dependent service quality need to be considered. In this paper, we present a combined time and space domain analysis on network reliability based on a continuous time Markov chain model. To this end, we introduce a new reliability metric that indicates the reliability level of URC for downlink transmissions. The metric computes the probability that a user located at a distance d from its base station can access a channel at time t with a received power level greater than a pre-defined threshold value, PTH. Moreover, the impact of channel failures on network performance is also analyzed.
