Abstract:
1. A method of controlling transmission power by a terminal in a wireless communication system, the method comprising: determining transmission power of a physical uplink control channel (PUCCH); determining transmission power of at least one first uplink shared channel (PUSCH) to which an uplink control information (UCI) is not mapped by scaling down the transmission power thereof among a plurality of PUSCHs on the basis of maximum transmission power of the terminal and the transmission power of the PUCCH; determining transmission power of at least one second PUSCH to which the UCI is mapped among the plurality of PUSCHs; and transmitting the UCI and uplink (UL) data through the PUCCH, the at least one first PUSCH, and the at least one second PUSCH, wherein the at least one first PUSCH and the at least one second PUSCH are allocated to a plurality of UL component carriers (CCs).
