Abstract
This invention is applied to a communication apparatus that uses one or more code words to transmit or receive appropriate information on a PUSCH. Assuming that the i-th code word CW_i is used alone to transmit the appropriate information, the communication apparatus of the invention uses a Formula (1) to calculate the number of resources Q′_i. When one or more code words are used to transmit the appropriate information, the communication apparatus uses a Formula (2) to calculate the number of resources Q′. Q i ′ = ⌈ O · M sc PUSCH - initial · N symb PUSCH - initial · β offset PUSCH ∑ r = 0 C - 1 K r ⌉ ( 1 ) Q ′ = min ( max ( ⌈ ( ∑ i 1 Q i ′ ) - 1 ⌉ , ⌈ O Q m UCI ⌉ ) , 4 · M sc PUSCH ) ( 2 )
