Adaptive Reduced Feedback Links for Distributed Power Allocation in Multicell MISO-OFDMA Networks

Abstract

For multi-antenna Orthogonal Frequency-Division Multiple Access (OFDMA) based multicell networks, the channel state information (CSI) of all users is required to share among base stations in order to perform distributed power allocation. However, the amount of feedback increases with the number of users, base stations, subcarriers and antennas. Therefore… (More)
