METHOD AND APPARATUS FOR CONTROLLING TRANSMISSION POWER IN WIRELESS COMMUNICATION SYSTEM
First Claim
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).

Abstract
Provided is a method and apparatus for controlling transmission power in a wireless communication system. A terminal sets transmission power of a physical uplink control channel (PUCCH). Among a plurality of physical uplink shared channels (PUSCHs), at least one PUSCH to which uplink control information (UCI) is not mapped is decreased in transmission power based on a maximum transmission power of the terminal and the transmission power of the PUCCH, and transmission power of at least one second PUSCH, of the plurality of PUSCHs to which UCI is mapped, is set. At this time, the UCI and uplink data are transmitted through the PUCCH, the at least one first PUSCH, and the at least one second PUSCH; and the at least one first PUSCH and the at least one second PUSCH are allocated to component carriers (CCs) of a plurality of uplinks (ULs).

10. A terminal in a wireless communication system, the terminal comprising:
-
a radio frequency (RF) unit for transmitting or receiving a radio signal; and a processor coupled to the RF unit, wherein the processor is configured for; 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). - View Dependent Claims (11, 12, 13, 14)
