A standard assumption in the design of ultra-reliable low-latencycommunication systems is that the duration between message arrivals is largerthan the number of channel uses before the decoding deadline. Nevertheless,this assumption fails when messages arrive rapidly and reliability constraintsrequire that the number of channel uses exceed the time between arrivals. Inthis paper, we consider a broadcast setting in which a transmitter wishes tosend two different messages to two receivers over Gaussian channels. Messageshave different arrival times and decoding deadlines such that theirtransmission windows overlap. For this setting, we propose a coding scheme thatexploits Marton's coding strategy. We derive rigorous bounds on the achievablerate regions. Those bounds can be easily employed in point-to-point settingswith one or multiple parallel channels. In the point-to-point setting with oneor multiple parallel channels, the proposed achievability scheme outperformsthe Normal Approximation, especially when the number of channel uses is smallerthan $200$. In the broadcast setting, our scheme agrees with Marton's strategyfor sufficiently large numbers of channel uses and shows significantperformance improvements over standard approaches based on time sharing fortransmission of short packets.
