Claim:
A terminal apparatus that transmits control information in a plurality of layers, the apparatus comprising: a determining section that determines an amount of resource of the control information in the plurality of layers; and a transmission section that transmits the control information based on the amount of the resource of the control information, wherein the amount of the resource Q CW#0+CW#1 of the control information is determined by equation 1: ⁢ ( Equation ⁢ ⁢ 1 ) Q CW ⁢ #0 + CW ⁢ #1 = ⌈ ( O + P ) · L CW ⁢ #0 + L CW ⁢ #1 ∑ r = 0 C CW ⁢ #0 - 1 ⁢ K r CW ⁢ #0 M CW ⁢ #0 sc PUSCH - initial · N CW ⁢ #0 symb PUSCH - initial × L CW ⁢ #0 + ∑ r = 0 C CW ⁢ #1 - 1 ⁢ K r CW ⁢ #1 M CW ⁢ #1 ⁢ sc PUSCH - initial · N CW ⁢ #1 ⁢ symb PUSCH - initial × L CW ⁢ #1 · β offset PUSCH L ⌉ where O indicates the number of bits in the control information, P indicates the number of error correction bits added to the control information, β offset PUSCH indicates an amount of offset, L indicates the number of the plurality of layers, L CW#0 and L CW#1 each indicate the number of layers assigned to a corresponding one of code words # 0 and # 1 , M CW#0SC PUSCH-initial and M CW#1SC PUSCH-initial indicate physical uplink shared channel (PUSCH) transmission bandwidths for the code words # 0 and # 1 , respectively, N CW#0symb PUSCH-initial and N CW#1symb PUSCH-initial each indicate the number of transmission symbols for a corresponding one of the code words # 0 and # 1 , K r CW#0 and K r CW#1 each indicate the number of bits in each code block r for a corresponding one of the code words # 0 and # 1 , and C CW#0 and C CW#1 each indicate the number of code blocks into which a data signal in a corresponding one of the code words # 0 and # 1 is divided.
