In the next generation of wireless communication, adaptive resource allocation techniques will play an important role to improve quality of service and spectral efficiency. In order to employ adaptive fairness scheduling for Multiple-Input Single-Output (MISO) Orthogonal Frequency-Division Multiple Access (OFDMA), the Channel State Information (CSI) belonging to all users is required at the base station. However, the amount of feedback increases with the number of users, transmit antennas and sub-channels. Therefore, it is important to perform a user selection at the receiver side without cooperation among the users and to quantize the CSI. In this paper, the reduced feedback channel designs are examined for MISO-OFDMA systems while providing fairness between the users.
