BASE STATION FOR DESCRAMBLING A HIGH SPEED SHARED CONTROL CHANNEL

摘要

A base station for descrambling a high speed shared control channel is provided to reliably separate scrambling codes generated for each UE(User Equipment) ID(Identification) in order to reduce generation of an erroneous detection by including a 1/2 rate convolution encoder, a rate matching unit and a mixing unit. In order to generate a code used by a base station in order to scramble an HS-SCCH(High Speed-Shared Control Channel), a 1/2 rate convolution encoder performs 1/2 rate convolution encoding on a UE ID to thus process the UE ID. The base station transmits a radio signal which provides payload data transferred through an HS-PDSCH(High Speed-Physical Download Shared Channel) related to the HS-SCCH to the UE. The HS-SCCH includes the first and second parts, and the code is used by the base station in order to scramble only the first part of the HS-SCCH.
