The mobile station of claim 59, wherein the mobile station uses the data channels such that at least the first one of the data channels and the third one of the data channels are coupled to an in-phase branch; the mobile station uses the data channels and the at least one control channel such that at least the second one of the data channels and the at least one control channel are coupled to a quadrature-phase branch. 61. The mobile station of claim 60, wherein the mobile station uses the data channels such that the fourth one of the data channels is coupled to the quadrature-phase branch. 62. The mobile station of claim 61, wherein the mobile station uses the data channels such that the fifth one of the data channels is coupled to the in-phase branch, and the mobile station uses the data channels such that the sixth one of the data channels is coupled to the quadrature-phase branch. 63. The mobile station of claim 59, the one or more processors further programmed to: allocate the first one of the data channels and the third one of the data channels to an in-phase branch; and allocate the at least one control channel and the second one of the data channels to a quadrature-phase branch. 64. The mobile station of claim 63, the one or more processors further programmed to: allocate the fourth one of the data channels to the quadrature-phase branch. 65. The mobile station of claim 64, the one or more processors further programmed to: allocate the fifth one of the data channels to the in-phase branch, and allocate the sixth one of the data channels to the quadrature-phase branch. 66. The mobile station of claim 50, the one or more processors further programmed to: generate C4,1 and C4,3. 67. The mobile station of claim 59, the one or more processors further programmed to: generate C4,1, C4,3, and C4,2.
