Center node: "adaptive transmission in cellular networks do physical layer rateless codes supersede power control"
  Abstract: Adaptive transmission schemes are a crucial aspect of the radio design for 5G wireless channels. The paper studies the performance of two classes of adaptive transmission schemes in cellular downlink. One class is based on physical layer rateless codes with constant transmit power and the other uses fixed-rate codes in conjunction with power adaptation. Using a simple stochastic geometry model for cellular downlink, the focus is to investigate the necessity of power control in a rateless coded adaptive transmission scheme. The performance of both rateless and fixed-rate coded adaptive transmission schemes are compared by evaluating the typical user success probability and rate achievable with the two schemes. Based on both theoretical analysis and simulation results, it is clearly shown that physical layer rateless coding simplifies the role of power control in an adaptive transmission scheme.
