Patent ID: 7907575

Claim:
A method for simultaneously transmitting a plurality of uplink channels including a Dedicated Physical Data Channel (DPDCH), a Dedicated Physical Control Channel (DPCCH), a High Speed—Dedicated Physical Control Channel (HS-DPCCH) and one or more Enhanced Dedicated Physical Data Channels (E-DPDCHs) by a user equipment (UE) to a base station, when a High Speed—Downlink Shared Channel (HS-DSCH) is configured for the UE, the method comprising: multiplying each of channelization codes denoted by Cch,SF,k, and generated as Orthogonal Variable Spreading Factor (OVSF) codes, to each of the plurality of uplink channels, wherein “SF” is a spreading factor and “k” is a channelization code number; mapping each of the plurality of uplink channels to an I branch or Q branch; and transmitting the plurality of uplink channels, multiplied by each of the channelization codes and mapped to the I branch or the Q branch, to the base station, wherein the DPCCH is mapped to the Q branch, and a channelization code of Cch,256,0 is multiplied to the DPDCH, wherein the DPDCH is mapped to the I branch, and a channelization code of Cch,SF,SF/4 is multiplied to the DPDCH, wherein the HS-DPCCH is mapped to the Q branch, and a channelization code of Cch,256,64 is multiplied to the HS-DPCCH, and wherein, when one E-DPDCH is transmitted, the E-DPDCH is mapped to the I branch, and a specific channelization code, other than the Cch,SF,SF/4 and the Cch,256,64, is multiplied to the E-DPDCH.
