Abstract:
A precoding matrix determination method and a precoding matrix determination device are provided. The precoding matrix determination method includes: dividing each of the groups of vertical-dimension beams into a plurality of subgroups of vertical-dimension beams, and dividing each of the groups of horizontal-dimension beams into a plurality of subgroups of horizontal-dimension beams; determining a first stage codebook in accordance with a Kronecker product of each subgroup of vertical-dimension beams acquired by dividing each of the groups of vertical-dimension beams and each subgroup of horizontal-dimension beams acquired by dividing each of the groups of horizontal-dimension beams; and selecting a plurality of columns of beams from the determined first stage codebook using a second stage codebook, and performing phase adjustment to determine a precoding matrix.

Claim (Index 1):
A precoding matrix determination method, comprising:\n determining vertical-dimension beam vectors and horizontal-dimension beam vectors, dividing the vertical-dimension beam vectors into a plurality of groups of vertical-dimension beams, and dividing the horizontal-dimension beam vectors into a plurality of groups of horizontal-dimension beams, every two adjacent groups of vertical-dimension beams comprising at least one vertical-dimension beam not overlapping the other vertical-dimension beams, and every two adjacent groups of horizontal-dimension beams comprising at least one horizontal-dimension beam not overlapping the other horizontal-dimension beams; dividing each of the groups of vertical-dimension beams into a plurality of subgroups of vertical-dimension beams, and dividing each of the groups of horizontal-dimension beams into a plurality of subgroups of horizontal-dimension beams, the number of the subgroups of vertical-dimension beams acquired by dividing any one of the groups of vertical-dimension beams being identical to the number of the subgroups of horizontal-dimension beams acquired by dividing any one of the groups of horizontal-dimension beams; determining a first stage codebook in accordance with a Kronecker product of each of the subgroups of vertical-dimension beams acquired by dividing each of the groups of vertical-dimension beams and each of the subgroups of horizontal-dimension beams acquired by dividing each of the groups of horizontal-dimension beams; and selecting a plurality of columns of beams from the determined first stage codebook using a second stage codebook, and performing phase adjustment to determine a precoding matrix.
