Limited feedback schemes for downlink OFDMA based on sub-channel groups
Abstract--In a downlink Orthogonal Frequency Division Multiple Access (OFDMA) system, optimally allocating sub-channels across mobile users can require excessive feedback of channe...

Resource allocation in OFDMA downlink with reduced feedback overhead
— Consider the problem of resource allocation on the downlink of a cellular OFDMA system. A fairness constraint is defined by a minimum data rate, a maximum bit-error rate and a...
