Scheduling for non-real-time services in orthogonal frequency division multiplex (OFDM) systems

摘要

Sub-carriers are allocated among the plurality of users in the OFDM system based on normalized channel gain values. Then, data bits are allocated for transmission on the allocated sub-carriers based on incremental transmission cost values. The channel gain values and the incremental transmission cost values are computed using a calculated fairness factor for each user in the system.
