Method and apparatus for transmitting uplink control information
Provided are a method and apparatus for determining the number of coded modulation symbols for uplink control information (UCI) when transmitting, in a wireless communication system, the UCI via a transport block processing over multiple slots (TBoMS) PUSCH to which TBoMS has been applied. The number of coded modulation symbols for the UCI is determined on the basis of the total number of bits being transmitted via the TBoMS PUSCH, and a value obtained by multiplying the number (Z) of slots configured for the TBoMS PUSCH by the sum of the number of resource elements that can be used for the transmission of the UCI in OFDM symbols for the TBoMS PUSCH in one slot through which the UCI is transmitted, from among the multiple slots.
