Abstract
In the novel method for data transmission via a radio interface in a radio communications system, at least two data channels are assigned to one connection. Each data channel can be distinguished by an individual spread code. In addition to data symbols, midambles with known symbols are transmitted in a data channel. The number of midambles being used for the connection is less than the number of data channels. The method is particularly suitable for use in TD/CDMA 3rd generation mobile radio networks.
Claims15
A method for data transmission via a radio interface in a radio communications system, which comprises the following steps:
- assigning one connection via a radio interface a given number of at least two data channels, whereby the data channels can be distinguished by an individual spreading code;
- transmitting in the data channels data symbols and, in addition, training sequences with known symbols;
- and
- utilizing for at least two of the data channels of the connection one common training sequence different from training sequences of other connections.
A radio station for data transmission in a radio communications system via a radio interface, comprising:
- a control device for assigning at least two data channels to a connection in a radio communications system;
- wherein each data channel can be distinguished by an individual spreading code, and
- wherein data symbols and, in addition, training sequences with known symbols are transmitted in a data channel;
- a signal processor using for at least two of the data channels of the connection one common training sequence different from training sequences of other connections.
