Abstract
In a method for data transmission in a radio communications system, a radio interface is subdivided into time slots for a transmission of bursts. In this case, the data are transmitted in data channels in a time slot, in which data channels can be distinguished by use of individual spread codes. A finite burst containing data symbols and at least one midamble with known symbols is used for data transmission in a data channel. At least one parameter is determined for the traffic conditions of the radio interface, and a ratio of a length of the midamble and a data part with data symbols is adjusted depending on the traffic conditions. The method is suitable in particular for use in 3 generation TD/CDMA mobile radio networks.
