BASE STATION, MOBILE STATION, REFERENCE SIGNAL TRANSMISSION METHOD, AND CHANNEL QUALITY MEASUREMENT METHOD

摘要

A base station that communicates with a mobile station by using a plurality of antenna ports includes a mapping information communication unit configured to generate mapping of reference signals for measuring channel state information of the antenna ports by combining, within a resource block, mappings of reference signals for measuring the channel state information, the mappings being defined for a predetermined number or less of the antenna ports, and configured to communicate information indicating the generated mapping to the mobile station; a multiplexer configured to multiplex the reference signals for measuring the channel state information in one or more resource elements in the resource block in accordance with the generated mapping; and a transmitter configured to transmit the reference signals for measuring the channel state information.
