Techniques for pilot stream remapping in ofdm wireless communication system

A method for receiving pilot data in a wireless communication system, the method comprising:

• determining a pilot pattern in at least one resource block for a pilot stream;
• and
• receiving the pilot stream based on the determined pilot pattern in the at least one resource block,
• wherein the at least one resource block comprises a plurality of subcarriers and a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols.

A base station apparatus for transmitting pilot data in a wireless communication system, the apparatus comprising:

• a pilot pattern determiner for determining a pilot pattern in at least one resource block for each of one or more pilot streams;
• a subcarrier mapper and an Orthogonal Frequency Division Multiplexing (OFDM) modulator for including the one or more pilot streams in the at least one resource block based on the determined respective pilot pattern;
• and
• a transmitter for transmitting the at least one resource block,
• wherein the at least one resource block comprises a plurality of subcarriers and a plurality of OFDM symbols.

A mobile station apparatus for receiving pilot data in a wireless communication system, the apparatus comprising:

• a receiver for receiving a signal including pilot stream in at least one resource block;
• a pilot pattern determiner for determining a pilot pattern in at least one resource block for the pilot stream;
• and
• an Orthogonal Frequency Division Multiplexing (OFDM) demodulator and a subcarrier demapper for extracting the pilot stream from the at least one resource block based on the determined pilot pattern,
• wherein the at least one resource block comprises a plurality of subcarriers and a plurality of OFDM symbols.
