Abstract:
1. A method for transmitting pilot data in a wireless communication system, the method comprising: determining a pilot pattern in at least one resource block for each of one or more pilot streams; and transmitting the one or more pilot streams based on the determined respective 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, wherein, based on the determined respective pilot pattern, the one or more pilot streams are included in two resource blocks such that they are symmetric in at least one of time and frequency, and wherein the determining of the pilot pattern in the at least one resource block for each of the one or more pilot streams comprises mapping pilot stream k to pilot pattern i based on one of the equations: where f and g each denote a functional operation with the combination of parameters within ( ), N denotes the pilot pattern sets, Cell ID denotes a base station identifier, PRU ID denotes a scheduled resource block identifier for a targeted mobile station, and STID denotes a station identifier of the targeted mobile station.
