It is now well known that employing channel adaptive signaling in wireless communication
systems can yield large improvements in almost any performance metric. Unfortunately …

In this study we analyze the downlink OFDMA system level performance for three different
channel quality indicator (CQI) reporting schemes. The effect of terminal measurement and …

In this paper we evaluate the performance of channel quality indicator (CQI) reporting
schemes in 3GPP UTRAN long term evolution (LTE) downlink (DL). In LTE, time and …

In a downlink orthogonal frequency division multiple access (OFDMA) system, optimally
allocating sub-channels across mobile users can require excessive feedback of channel …
