PERIODICAL FEEDBACK DESIGN FOR THREE-DIMENSIONAL MULTIPLE-INPUT MULTIPLE-OUTPUT (3D-MIMO)

摘要

Systems, methods, apparatuses, and computer program products for a periodical feedback design for three-dimensional (3D) multiple-input multiple-output (MIMO) are provided. One method includes configuring a channel state feedback into at least two feedback instances with reduced sizes for transmission over one or more physical feedback channels. The channel state feedback may include a codebook index, indices of channel, or precoder quantization. The method may also include encoding codebook index, indices of channel, or precoder quantization of the channel state feedback, and filling the encoded codebook index, indices of channel, or precoder quantization into the at least two feedback instances of the one or more physical feedback channels.
