Dear Ajit Singh,
in our 5G LLS, we assume that a node transmits with a constant average power, as set in the parameters. Also, with a full buffer assumption (no traffic model), each node always transmits when scheduled. Since the current scheduler is a fixed one, it is not changing with time. Therefore, the power consumption for each node, is the same in each subframe an can easily be calculated. However, I am not sure whether this was what you were looking for.
Also, I am not quite sure, what you mean by including fading effects? Since there is no power control implemented in our simulator, the channel state does not influence the transmit power and therefore energy consumption.
