摘要： The invention provides a method of interleaving a source data stream using an interleaver pattern in a transmitter. A mother interleaver pattern and an interleaver parameter are accessed. The mother interleaver pattern is modified using said interleaver parameter. Then, the modified interleaver pattern is applied in the transmitter for interleaving the source data stream. The interleaver parameter used by the transmitter for modifying said mother interleaver pattern differs from the interleaver parameter used simultaneously by at least one other transmitter that transmits data at the same time on the same channel. The invention further provides a corresponding deinterleaving method. By decorrelating the interleaver processes in the different streams, the inter-stream interference is reduced.

摘要： A hybrid ARQ retransmission method in a communication system wherein data packets consisting of identical or partly identical modulation symbols encoded with a forward error correction (FEC) technique prior to transmission are retransmitted based on a repeat request and subsequently bit-level combined on the basis of soft-information values. The calculation of the soft-information values being input into an FEC decoder comprises the steps of calculating and buffering the soft-information values of the most significant bits (MSBs) of each (re)transmitted data packet; combining, for matching modulation symbols, the current soft-information values of the MSBs with the buffered soft-information values of at least one of the previous received transmitted packets; and calculating the soft information for at least some of the remaining bits (XSBs) from the combined soft information values of the MSBs.

摘要： The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal proposed by the invention. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed new control channel signal according to the invention. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.
