Patent ID: 7903618

Claim:
A method for transmitting enhanced packet data in a mobile communication system, the method comprising the steps of: generating a dedicated physical control channel (DPCCH) using an Orthogonal Variable Spreading Factor (OVSF) code (256,0) and a quadrature-phase (Q) channel; generating a dedicated physical data channel (DPDCH) using an OVSF code (SF DPDCH , SF DPDCH /4) and an in-phase (I) channel, where SF DPDCH denotes a spreading factor of the DPDCH; generating an E-DPCCH using an OVSF code (SF E-DPCCH , 1) and the I channel, where SF E-DPDCH denotes a spreading factor of an OVSF code to be allocated to a dedicated control channel (E-DPCCH) for supporting transmission of enhanced uplink packet data; and generating an E-DPDCH using an OVSF code (SF E-DPDCH , SF E-DPDCH /2) and the Q channel, where SF E-DPDCH denotes a spreading factor of an OVSF code to be allocated to a dedicated data channel (E-DPDCH) for supporting transmission of the enhanced uplink packet data.
