Latest Patents
Kari holds a patent for her invention titled "Codebook Design and Structure for Multi-Granular Feedback." This inventive work introduces a method for selecting a first precoding matrix from a first codebook that comprises sets of rank-specific precoding matrices. The invention optimizes the use of these matrices by ensuring that there are fewer matrices associated with higher ranks than with lower ranks, and it specifies that matrices above a certain rank are exclusively diagonal. The selected first precoding matrix serves to choose a rank-specific second precoding matrix from a second codebook, creating a joint precoder tailored to a desired rank. This innovation has implications for efficient information transmission over uplink channels in communication networks.
