... bounding constraints. We propose a heuristic solution where in order to get a good starting point we solve the problem by ignoring the bounding constraints (26)and(27). This problem results in output ... strategies to minimize queu- ing delay for single-user single-carrier systems. Similarly dynamic programming was adopted in [22] for scheduling packets over a time-slotted single-user wireless link. Perhaps the ... algorithm gives the remaining power by w aterfilling while the algorithm presented in [8] gives all the remaining resources to the user with highest mean channel gain value. In order to evaluate...
