[en] This work considers the scheduling problem for the packets with strict maximum tolerable delay (deadline) constraint. We discuss a multiuser scheduling scheme which schedules the users based on their instantaneous channel conditions, packet deadline and backlog of the buffered packets. The scheme is analyzed in large system limit for the single and multicell cases. The aim is to minimize the system transmit energy while providing hard deadline guarantees for every packet. We analyze the effect of intercell interference on the deadline delay constrained systems and derive an upper bound on the achievable capacity for a given cell size. Numerical results provide the characterization of the operating region of a deadline delay constrained multicell system as a function of spectral efficiency.
