Data-transmission method for transmitting data over a subscriber's transmission link uses a reference sequence, a reference process and frequency ranges

摘要

A reference sequence (RS) and a reference process are preset so as to transmit the RS. For transmitting the RS there is a main frequency range (HB), in which a first under-frequency range (UB) is preset that is not to be used during transmission of useful data. A first test signal is generated starting from the RS. A decrease in spectral power intensity is forced for a first signal quota. An independent claim is also included for a device for transmitting data over a subscriber's transmission link.
