Abstract

An apparatus for a wireless communication system is to transmit a reference signal on a common set of resource elements, REs, the common set of REs used by one or more further apparatuses in the wireless communication system to transmit the reference signal so that the reference signals of the apparatus and of the one or more further apparatuses use the same REs. The reference signal is transmit using OFDM symbols and the same sequence having a zero auto correlation property is applied to each OFDM symbol. A phase correction is applied to an OFDM symbol before transmission, wherein a correction factor of the phase correction depends on a comb factor and a comb offset of the OFDM symbol and is independent of the resource element.
