Abstract

A method of transmitting and receiving information about successive orthogonal codes assigned to user data for spreading on a control channel before transmission of the user data on a plurality of code channels in an HSDPA (High Speed Data Packet Access) communication system. A Node B determines an offset between a starting orthogonal code among the assigned orthogonal codes and the first of a plurality of successive orthogonal codes available to the HSDPA communication system, determines the number of the assigned orthogonal codes counted from the starting orthogonal code being the number of the code channels, forms orthogonal code information indicating the offset and the number of the orthogonal codes, and transmits the orthogonal code information to a UE.
