Abstract:
1. A method for simultaneously transmitting a plurality of uplink channels including a Dedicated Physical Data Channel (DPDCH), a Dedicated Physical Control Channel (DPCCH), and one or more Enhanced Dedicated Physical Data Channel (E-DPDCH) by a user equipment (UE) to a base station, when a High Speed-Downlink Shared Channel (HS-DSCH) is not 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 a 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, and wherein, when one E-DPDCH is transmitted, the E-DPDCH is mapped to the Q branch, and a specific channelization code, other than the Cch, 256, 0 and the Cch, SF, SF/4, is multiplied to the E-DPDCH.
