Abstract: Recently, codebook-based MIMO precoding has been actively studied since it offers good tradeoff between beam-forming gain and the required amount of feedback information. For the codebook based feedback, the feedback overhead depends on the codebook size. Usually for 4 Tx and 8 Tx codebook, the size can be as big as 64. In this contribution, we propose a differential PMI feedback scheme to reduce the feedback overhead. Also, a codebook reordering for differential PMI feedback is also presented. It is recommended to consider this differential feedback for LTE-A DL MIMO system since it can greatly reduce the PMI feedback overhead.
