Abstract
Method and apparatus are provided for determining a power or a number of repetitions for a physical uplink control channel (PUCCH) transmission that includes a number of uplink control information (UCI) bits. A power for the PUCCH transmission is determined based on an adjustment factor that uses different functions depending on the number of UCI bits or based on a type of the UCI bits. A number of repetitions for the PUCCH transmission that is with a spatial filter over a number of symbols is determined from a reference number of repetitions and one or more of a reference number of UCI bits, a reference number of symbols, or a reference spatial filter.
