8-TRANSMIT ANTENNA REFERENCE SIGNAL DESIGN FOR DOWNLINK COMMUNICATIONS IN A WIRELESS SYSTEM

摘要

Systems and methods are disclosed for mapping reference signals for antenna ports in a plurality of resource blocks among resource blocks in a subframe within an orthogonal frequency division multiplexing (OFDM) communication system. This method includes selecting at least one predetermined resource elements for transmitting in the plurality of resource blocks using a first number of antenna ports. This method also includes selecting a second number of antenna ports and mapping a plurality of reference signals relating to the second number of antenna ports using a second number of OFDM symbols.
