MAPPING AND SIGNALING OF COMMON REFERENCE SYMBOLS FOR MULTIPLE ANTENNAS

摘要

A method, a network base station, and a user communication device for transmitting data on an orthogonal frequency-division multiplexing carrier are disclosed. An antenna array may transmit a signal decodable by a legacy user communication device designed for compatibility with a legacy set of transmission antennas. A processor 210 may encode a subframe of the signal with a legacy set of common reference symbols and a supplemental set of common reference symbols referring to the antenna array.
