Abstract:
1. A method of transmitting information about successive orthogonal codes assigned to user data for spreading on a control channel before transmitting the user data on a plurality of code channels to a UE (User Equipment) in a Node B of an HSDPA (High Speed Data Packet Access) communication system, the method comprising the steps of: determining an offset between a starting orthogonal code among a assigned orthogonal codes and a first of a plurality of successive orthogonal codes available to the HSDPA communication system; determining a number of the assigned orthogonal codes counted from the starting orthogonal code being a number of the plurality of code channels; and forming orthogonal code information indicating the offset and the number of the orthogonal codes and transmitting the orthogonal code information to the UE.
