Abstract

A discret-time model was discussed for transmission scheduling over a fading channel. Arriving data was placed into a transmission buffer with dynamics Sn+1=max{Sn+An+1-Un, A n+1}, where at time n, Sn is the buffer, An is the amount of arriving data and Un is the amount of data removed from the buffer. For this model, the optimal trade-off between the average queueing delay and the long-term average power was characterized in asymptotic regime of large delays. It was shown that one of the policies, called a 'channel threshold policy' essentially obtains the optimal rate of decrease in average delay as the average power increases to infinity.
