- Abstract
- This thesis studies joint scheduling and power control in wireless networks. It employs opportunistic scheduling in order to exploit multiuser diversity and adopts CDF-based scheduling (CS). The CS has the advantage of enabling tractable mathematical analysis by predicting scheduling performance based on a control parameter called user weight, which can be adjusted to meet the desired quality of service (QoS). The thesis formulates a problem of jointly deciding user weights and power that minimizes overall uplink transmit power while satisfying the data rate requirement. The formulated problem is not convex but can be decomposed into two subproblems which are convex. According to simulations the proposed scheme turns out to significantly reduce uplink transmit power, when compared with the schemes that perform user scheduling and power control separately.
