Abstract | |||||||||||||||||
| 1 In this paper, we propose a power optimal opportunistic scheduling scheme for a multiuser single hop Time Division Multiple Access (TDMA) system. We formulate the problem of minimizing average transmission power subject to minimum rate constraints for individual users. We suggest a scheme based on stochastic approximation to implement the policy and prove the convergence and stability of this algorithm. We demonstrate through simulations that the algorithm converges to optimal policy in a reasonable number of iterations for it to be practically useful. Our algorithm is applicable for independent and identically distributed (i.i.d.) as well as Markovian channel fading. Finally, we extend the power optimal scheduling algorithm for providing temporal fairness among users. | |||||||||||||||||
