WIRELESS COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, TRANSMISSION METHOD, AND ESTIMATION METHOD

摘要

A base station (110) is provided with an antenna group (112) arranged two-dimensionally in the horizontal direction and the vertical direction. The base station (110) transmits reference signals using a plurality of antennae (113) aligned in the horizontal direction, and second antennae (115) arranged in the vertical direction in the position of a first antenna (114) which is one of the plurality of antennae (113). A mobile station (120) estimates, on the basis of each of the reference signals transmitted by the plurality of antennae (113) and the second antennae (115), the channel states of antennae (116) in the antenna group (112) which are different to the plurality of antennae (113) and the second antennae (115).
