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 5):
The precoding matrix determination method according to  claim 4 , wherein\n X 2 =X 1 , or X 2 =[( X v,1 B 1 )\u2297 X h,1 ( X v,2 B 2 )\u2297 X h,2 L ( X v,q B q )\u2297 X h,q L ( X v,Q B Q )\u2297 X h,Q ], or X 2 =[X v,1 \u2297( X h,1 D 1 ) X v,2 \u2297( X h,2 D 2 ) L X v,q \u2297( X h,q D q ) L X v,Q \u2297( X h,Q D Q )], or X 2 =[( X v,1 B 1 )\u2297( X h,1 D 1 ) L ( X v,q B q )\u2297( X h,q D q ) L ( X v,Q B Q )\u2297( X h,Q D Q )], where B q  represents a m q \u00d7m q  diagonal matrix, D q  represents a l q \u00d7l q  diagonal matrix, m q  represents the number of vertical-dimension beams comprised in the q th  subgroup of vertical-dimension beams of the group X v  of vertical-dimension beams, and l q  represents the number of horizontal-dimension beams comprised in the q th  subgroup of horizontal-dimension beams of the group X h  of horizontal-dimension beams.
