Coordinated Multi-point Joint Transmission with Partial Channel Information Feedback
Paper i proceeding, 2013

This paper studies the data transmission efficiency of a coordinated multi-point (CoMP) network in the presence of partial channel state information (CSI). The system throughput is obtained in the case where the base stations are provided with a quantized channel phase information. Assuming slow-fading channels, discussions about the optimal quantization boundaries and adaptive power allocation are presented. Moreover, we demonstrate the equivalency of the quantized CSI scheme with a hybrid automatic repeat request protocol, in terms of throughput. Considerable performance improvement is observed with even a single bit feedback per user.
