METHOD AND APPARATUS OF CONRTOLLING TRANSMISSION POWER IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A power transmission controlling method in a wireless communication system is provided to properly allocate transmission power to a UL channel in case a terminal restricts maximum transmission power. CONSTITUTION: A terminal sets up the transmission power of a PUCCH(Physical Uplink Control Channel)(S300). The terminal reduces the transmission power of 1 PUSCH in order for UCI(Uplink Control Information) not to be mapped(S310). The terminal sets up the transmission power of 2 PUSCH(S320). The terminal transmits UL(UpLink) data through 1 PUSCH and 2 PUSCH(S330).
