High Performance and Low Complexity Scheduling Method for Adaptive Resource Usage in OFDMA Wireless Relay Networks
Abstract:
A method for scheduling transmissions in wireless network includes receiving information ranging from conventional data to real-time streaming applications into a basestation of an OFDMA wireless relay network and scheduling transmission of the information from the basestation by influencing adaptive frame segmentation and access hop reuse in the transmission of the information for achieving higher transmission flow of the information, Where the scheduling is formulated as an integer program, the scheduling includes solving a linear programming relaxation of the integer program and rounding to integral allocations with allocation to at least one of a subset of wireless users and subsets of relays in the network for obtaining frame segmentation and reuse. Where the scheduling is formulated by following a bisection approach to guide adaptation of the frame segmentation, the scheduling determines a subset of users with maximum flow per unit resource for a given frame segmentation and the resulting flow from current and previous scheduling being used to guide adaptation of frame segmentation towards convergence.
