Abstract (en)

[origin: WO9920011A1] At least two data channels are transmitted via a radio interface in a radio communications system. The data channels can be distinguished by an individual spread code. A midamble with known symbols is transmitted in addition to data symbols in a data channel, the average transmission power of the midamble being greater than that of the data symbols. The invention is especially suitable for use in 3rd generation TD/CDMA mobile radio networks.
