摘要：
An apparatus and a method are provided by which a plurality of data streams are transmitted and at least one common pilot signal and at least one dedicated pilot signal are transmitted with the plurality of data streams, wherein the number of dedicated pilot signals is set depending on the number of data streams. Moreover, an apparatus and a method are provided by which a plurality of data streams is received, wherein the data streams comprise at least one common pilot signal and at least one dedicated pilot signal, and channel estimation is performed based on the at least one common pilot signal and the at least one dedicated pilot signal.
