More Information
Summary:This disclosure provides an apparatus including processing circuitry that divides a plurality of antenna ports of the apparatus into multiple antenna groups. Each antenna group includes one or more antenna ports that are coherent to each other within the respective group. The antenna ports from different groups are not coherent to each other. The processing circuitry determines, for each antenna group, one or more layers to be transmitted by the respective antenna group. The processing circuitry selects, for each antenna group, one of a plurality of precoder submatrices based on a number of the one or more antenna ports included in the respective antenna group and a number of the one or more layers to be transmitted by the respective antenna group. The processing circuitry constructs one or more precoder matrices for the plurality of antenna ports based on one or more combinations of the selected precoder submatrices.
