We seek to characterize the performance of scheduling policies for wireless systems that are based on Cumulative Density Functions (CDF) of the channels. We first derive optimal scheduling policies for a two-user system under max-sum rate and max-min rate performance criteria subject to the same temporal resource constraints as those under CDF-based(More)
We consider the problem of controlling the user service delays for a system that employs a scheduling scheme based on Cumulative Density Functions (CDF) of user channels in a correlated Rayleigh fading environment. We first formulate and solve this control problem as a Markov Decision Process (MDP) on the system state space formed by the user channel(More)
Abstract We consider the resource allocation problem in cellular networks which support Device-to-Device Communications (D2D). For systems that enable D2D via only orthogonal resource sharing, we propose and analyze two resource allocation policies that guarantee access fairness among all users, while taking advantage of multi-user diversity and local D2D(More)
In this work, we exploit historical channel data via linear programming and machine learning tools to perform opportunistic scheduling for multiuser wireless systems under temporal fairness constraints. We first derive linear program-based scheduling (LPS) algorithms that compute the scheduling decisions from a window of past user metrics. The proposed(More)
We propose two novel methods of service delay control for multiuser wireless systems that employ a scheduling scheme based on the Cumulative Density Function (CDF) of user channels in correlated fading environments. The first method allows for different hard delay deadlines for the users. The second method relaxes the deadline enforcement into(More)
We consider the delay control problem for multiuser opportunistic scheduling policies in wireless systems. First, the user selection behaviors of opportunistic scheduling policies are examined to highlight the delay and resource starvation issues. We then propose and analyze two schemes for delay control and starvation prevention that are both effective and(More)
