Delay control for CDF scheduling with deadlines

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 “soft” deadlines in order to take better advantage of multiuser diversity. Both methods offer excellent performance while still preserving the temporal fair resource allocation property of the CDF scheduling policy.
