CA 2740814

A base station apparatus includes multiple antennas including M physical antennas (#1, #3, #5, #7) of a first group and M physical antennas (#2, #4, #6, #8) of a second group; a reference signal multiplexing unit which multiplexes at least M types of reference signals (P#1-P#4) to resource blocks of a downlink signal; and a transmitting unit which wirelessly transmits the downlink signal. The M types of reference signals are multiplexed to a first resource block and a second resource block in the same arrangement pattern. The M types of reference signals (P#1-P#4) within the first resource block are transmitted from the physical antennas (#1, #3, #5, #7) of the first group. The M types of reference signals within the second resource block are transmitted from the physical antennas (#2, #4, #6, #8) of the second group.

L'invention porte sur un appareil de station de base qui comprend une pluralité d'antennes physiques comprenant un premier groupe de M antennes physiques (N°1, N°3, N°5, N°7) et un second groupe de M antennes physiques (N°2, N°4, N°6, N°8); une unité de multiplexage de signaux de référence qui multiplexe au moins M sortes de signaux de référence (P n°1 à P n°4) dans des blocs de ressource de signaux descendants; et une unité d'émission qui émet de façon sans fil les signaux descendants. Les M sortes de signaux de référence sont multiplexés dans des premier et second blocs de ressource dans le même motif d'agencement. Les M sortes de signaux de référence (P n°1 à P n°4) dans le premier bloc de ressource sont émis par le premier groupe d'antennes physiques (N°1, N°3, N°5, N°7). Les M sortes de signaux de référence dans le second bloc de ressource sont émis par le second groupe d'antennes physiques (N°2, N°4, N°6, N°8).
