A TFCI transmission scheme using optimal TFCI transmission bit patterns for the DPCH and DSCH in the hard split mode of the W-CDMA standard. The DPCH TFCI bits (TFCI1) and the DSCH TFCI bits (TFCI2) are mapped to their corresponding bit positions and then transmitted such that TFCI code word errors are minimized and communication reliability is improved. When the TFCI1 to TFCI2 ratio is 5:5, the TFCI transmission bit pattern has alternating TFCI1 and TFCI2 bits. For other ratios, such as 1:9. 2:8, 3:7, and 4:6, the bit patterns are obtained by considering situations where the number of TFCI bits is 6 or 7, while bit patterns for respective conjugate ratios (9:1, 8:2, 7:3, and 6:4) are obtained by reversing all 0 and 1 bits of the previously obtained bit pattern for that ratio.
