Abstract
BF weight vector determination is executed for each of M number of streams. In a first stage, by repeating switching of transmission BF weight (transmission beam) candidates in a small base station, a transmission BF weight vector with the best reception quality in a user apparatus UE is selected from among tried transmission BF weight vectors. In a second stage, by repeating switching of reception BF weight (reception beam) candidates in the user apparatus, a reception BF weight vector with the best reception quality in the user apparatus UE is selected from among tried reception BF weight vectors.
