Abstract:
Non-zero power channel state information reference signals (CSI-RS) are transmitted only on a subsampled pattern of antennas within an antenna array. Based on the transmitted CSI-RS, channel state information is determined for all antennas within the antenna array by, for example, precoder matrix indicator (PMI) interpolation or channel quality indicator (CQI) compensation. The determination of CSI for all antennas within the antenna array may be made by a user equipment receiving the subsampled CSI-RS or a base station transmitting the subsampled CSI-RS.
