Abstract | |||||||||||||||||
| 1 In this paper, we propose a power optimal opportunistic scheduling scheme for a multiuser sin-gle 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 stochastic approximation based scheme to implement the policy and prove the convergence and sta-bility of this algorithm. We demonstrate through simulations that the algorithm converges to optimal policy in reasonable 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. | |||||||||||||||||
