Resource allocation with reducing uplink CQI feedback in OFDMA

Abstract:

According to the features that uplink CQI feedback is high and not fair enough in OFDMA system, the reducing feedback resource allocation algorithm is proposed. Users in the cell center with higher SNR do not need feedback CQI, and users in the cell edge with lower SNR adopt l B feedback when the load is low while the Best-M is adopted and the load is heavy. Meanwhile, according to the Best-M project, the first user preference is proposed. On the premise of ensuring the necessary feedback information of resource allocation, the proposed algorithm trades off between complexity and performance, and meets the users' fairness
