Short Packet Communication under Random Arrival Of Data
Short packet communication is considered to be a key enabler in supporting two important application scenarios of 5G, namely: (a) massive machine type communication (MTC) and (b) ultra-reliable low-latency communication (uRLLC). With the emergence of new use case scenarios, there is a need to develop a theory for short packet communication which takes account of reliability as well as latency. Information theory has provided models to capture the uncertainty associated with the underlying channel such as noise, fading, and interference. In general, these works do not capture random arrival of data at the users. On the other hand, network theory provides mathematical tools or models to capture the random arrival of data and latency aspects of communication. However, it does not capture the underlying physical channel. The unification of these two theories can provide a more accurate model where it is required to consider the aforementioned aspects jointly. This talk will primarily focus on some of our initial results in these directions with and without secrecy constraints
