Abstract  Abstract

PURPOSE: A base station for scrambling a high speed shared channel is provided to reduce generation of detection having an error by properly separating a scrambling code created for each UE ID. CONSTITUTION: A base station includes a rate 1/2 convolutional encoder(14) which receives a UE ID and generates a rate 1/2 convolutional encoded code. A rate matcher receives a code and generates a rate-matched scrambling code. A mixing unit mixes an encoded HS-SCCH(High Speed-Shared Control CHannel) data and a scrambling code. A 16-bit UE ID is inputted to the rate 1/2 convolutional encoder(14) together with eight 0 bits added at the end of an input stream. As a result, the input stream is XUE1,...,XUE16, 0, 0, 0, 0, 0, 0, 0, 0. After being processed by the rate 1/2 convolutional encoder(14), an output code has 48 bits in length. In order to reduce the length of the code to a preferable 40-bit length, eight bits are cut. After rate matching, the scrambling code has the effective length of 40 bits.
