METHOD AND ARRANGEMENT FOR TRANSMITTING DATA OVER A RADIO INTERFACE IN A RADIOCOMMUNICATIONS SYSTEM

摘要

The invention relates to a method and arrangement for transmitting data in a downlink direction over a radio interface in a radiocommunications system. To this end, a base station transmits the data in radio blocks in a downlink direction to a radio station according to a time-division multipex method. Returning training sequences are inserted between the radio blocks such that the utilized transmitter power for transmitting the data is not decreased. The radio station carries out a channel estimation with the assistance of the training sequences.
