| 摘要 |
The embodiments of the invention relate to a transmission method (MET-TA) and transmitter apparatus (TA) for composing a transmit signal. The transmission method contains the step of composing a transmit signal that comprises in a first fraction of a first radio resource element (RRE2, RRE5, RRE7) a first fraction of a first reference signal (P1) superimposed with a data signal (DS2, DSS, DS6), in a first fraction of at least a second radio resource element (RRE6) at least a second fraction of said first reference signal (P1 ), in at least a second fraction of said first radio resource element (RRE2, RRE5, RRE7) a first fraction of at least a second reference signal (P2, P3, P4) superimposed with said data signal (DS2, DS5, DS6) and in at least a second fraction of said at least second radio resource element (RRE6) at least a second fraction of said at least second reference signal (P2, P3, P4). The embodiments of the invention further relate to a method (MET-RA) and receiver apparatus (RA) for channel estimation. The channel estimation method contains the step of estimating a transmission channel (TC) of a receive signal that comprises in a first fraction of a first radio resource element (RRE2, RRE5, RRE7) a first fraction of a first reference signal (P1) superimposed with a data signal (DS2, DS5, DS6), in a first fraction of at least a second radio resource element (RRE6) at least a second fraction of said first reference signal (P1), in at least a second fraction of said first radio resource element (RRE2, RRE5, RRE7) a first fraction of at least a second reference signal (P2, P3, P4) superimposed with said data signal (DS2, DS5, DS6) and in at least a second fraction of said at least second radio resource element (RRE6) at least a second fraction of said at least second reference signal (P2, P3, P4). |
