In a telecommunication network, pilot signals are provided in OFDM (orthogonal frequency division multiplexing) frames to enable the SC-FDMA (the single-carrier frequency division multiple access) concept to work with the OFDMA concept in uplink substantially harmonically, wherein each OFDM frame includes a predetermined plurality of OFDM symbols, and at least one pilot signal is placed in addition to other data and/or signals within at least one existing OFDM symbol of said predetermined plurality of OFDM symbols. |
