In a centralised cooperative relay scenario, a dynamic time slot allocation scheme is proposed to maximise the system throughput of cognitive radio networks by considering variant channel capacities and users' demands. Key parameters and propositions are verified theoretically with extended application cases and constraints, as a significant improvement on the traditional fixed scheme. Performance improvement has been verified by quantitative results.
