Abstract:
1. A method of de-rate matching an initial transmitted packet data between a collection buffer and combining buffer in a receiver, the initial transmitted packet data being rate-matched in a transmitter in a high-speed packet transmission system, comprising the steps of: (a) receiving from the transmitter, high-speed shared common control channel (HS-SCCH) information comprising a predetermined hybrid automatic repeat request (HARQ) parameter associated with packet transmission, and decoding the HS-SCCH information; (b) generating and storing memory information related to a plurality of memory addresses for de-rate matching of the initial transmitted packet to be received according to the decoded HARQ parameter; (c) initializing data stored at memory addresses of the combining buffer including memory addresses for bits punctured during the rate matching; and (d) sequentially storing the initial transmitted packet data output from the collection buffer at memory addresses other than the memory addresses for the punctured bits according to the memory information in the combining buffer.
