Abstract: The present invention relates to a method for transmitting data via a physical channel in a communication system, the channel being used by at least one first communication device and one second communication device and transmitting data with a defined bit rate. According to the present invention, the data to be transmitted (TD) is composed of load data (LD) and identification data (ID) for identifying the second communication device, the load data (LD) and identification data (ID) are coded separately from one another, the respective coding (C_LD, C_ID) takes place in such a way that an identical bit rate is achieved after the coding operation for the load data (LD) and the identification data (ID) and the rate is matched to the bit rate that has been defined for the physical channel by a rate matching mode, which defines which bits are punctured or repeated in a data stream. The rate matching model for load data (LD) and identification data (ID) is identical.

The subscriber station estimates the direction of a control vector in an M-dimensional vector space using measurements of the downlink signals, it detects a deviation of the estimated direction from the direction of a reference control vector and transmits information representative of the deviation to the base station. The base station then adapts the weighting vector using the representative information.

In the base stations, the weighting vectors are assigned to the code words in various ways, so that upon receipt of an identical code word, the base stations weight the downlink signal using different weighting vectors.

Abstract: A transmitting device in a mobile communication system is disclosed. In the transmitting device, an encoder receives an information bit stream in a frame, which is as long as an integer multiple of a predetermined value, and generates an information symbol, a first panty symbol, and a second parity symbol by encoding each information bit. An interleaver sequentially arranges the information symbols and the first and second parity symbols by rows in an array with an integer number of rows and an integer number of columns. The interleaver reorders the columns in the array according to a predetermined rule. The interleaver further outputs a plurality of radio frames in a stream, by reading the symbols by going down each column, starting at the leftmost column and proceeding right. Each radio frame has a predetermined size.
