Abstract
A transmission device in a wireless communication system: maps respective reference signals for a plurality of antennas to frequency resources; and transmits the reference signals on the frequency resources. Mapping the reference signals to the frequency resources comprises mapping the reference signals such that: (i) the frequency difference between a frequency resource ffor a reference signal of an antenna Vand a frequency resource ffor a reference signal of an antenna Vis Δf; and (ii) the frequency difference between the frequency resource fand a frequency resource ffor a reference signal of an antenna Vis Δf, wherein m is an antenna index along a first direction, and n is an antenna index along a second direction orthogonal to the first direction.
