Abstract
Disclosed is a method for performing, by a UE, carrier aggregation (CA) via a first carrier wave and a second carrier wave, on the basis of switching of a transmission chain, in a wireless communication system according to various embodiments. Disclosed are the method and apparatus therefor, the method comprising the steps of: reporting a first power headroom report (PHR) for the first carrier wave and a second PHR for the second carrier wave; receiving transmission chain switching information for changing a setting of a transmission chain for each of the first carrier wave and the second carrier wave; and assigning first transmission power for the first carrier wave and second transmission power for the second carrier wave, wherein one or more transmission chains are assigned to the second carrier wave via the transmission chain switching information, and when a power control value set for the second carrier wave is greater than first maximum output power of the one or more transmission chains, the second transmission power can be assigned on the basis of the number of all transmission chains for performing the CA and the number of the one or more transmission chains.
