Abstract:
1. A method for transmitting a reference signal in a wireless communication system, carried in a transmitter, the method comprising: generating a first sequence and a second sequence; mapping the first sequence to reference symbols in a resource block; mapping the second sequence to the same reference symbols in the resource block; and transmitting a first reference signal (RS) based on the first sequence through a first antenna, and a second RS based on the second sequence through a second antenna, wherein the resource block consists of a plurality of orthogonal frequency division multiplexing (OFDM) symbols and a plurality of subcarriers, each element of the resource block is a resource element, and the reference symbols are resource elements of a specific position in the resource block, and wherein each of the first sequence and the second sequence is mapped to first reference symbols included the reference symbols on a subcarrier basis in one OFDM symbol in the resource block, and is then mapped to second reference symbols included the reference symbols on a subcarrier basis in a next OFDM symbol.
