Embodiment Construction

[0060] The preferred embodiments of the present invention will be described below with reference to the drawings. In the following description, well-known functions or configurations are not described in detail because they may obscure the present invention with unnecessary details.

[0061] The present invention provides a method, which can ensure the compatibility between HSDPA UE / Node B and non-HSDPA Node B / UE. For this purpose, a new UL-DPCH and a new DL-DPCH should be defined, and transmitters and receivers operating on the new UL-DPCH and DL-DPCH should also be provided.

[0062] First, a method for transmitting uplink HSDPA control information and a structure of UL-DPCCH carrying HSDPA control information are provided. In addition to the regular UL-DPCCH, or multiple new UL-DPCCHs are configured to support HSDPA.

[0063] Generally speaking, all OVSF (Orthogonal Variable Length Spreading Factor) codes can be used for UEs, which means that channelization codes are sufficient...
