METHOD AND APPARATUS FOR TRANSMITTING UPLINK SIGNALS IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for transmitting first and second physical uplink channels by a user equipment (UE) in a carrier aggregation based wireless communication system, the method comprising:
- performing a procedure for transmitting the first physical uplink channel in subframe #n of a first cell; and
performing a procedure for transmitting the second physical uplink channel signal in subframe #n of a second cell,wherein if a sum of transmit power of the first physical uplink channel and transmit power of the second physical uplink channel exceeds a predetermined maximum transmit power set for the UE and if the first and second physical uplink channels include uplink control information (UCI) having same priority, a transmit power of one of the first and second physical uplink channels transmitted in a cell having a lower cell priority is reduced.

Abstract
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for a terminal controlling uplink power in a carrier aggregation-based wireless communication system, comprising the steps of: configuring a first cell and a second cell; transmitting a first PUCCH signal from subframe #n in the first cell; and transmitting a second PUCCH signal from subframe #n in the second cell, wherein when the sum of transmit power of the first PUCCH signal and transmit power of the second PUCCHJ signal exceeds a predetermined maximum transmit power configured to the terminal, the transmit power of the PUCCH signal having a lower priority from among the first UCCH signal and the second PUCCH signal is reduced or the transmission is dropped.

6. A user equipment (UE) in a carrier aggregation based wireless communication system, the UE comprising:
-
a radio frequency (RF) unit; and a processor, wherein the processor is configured to perform a procedure for transmitting a first physical uplink channel in subframe #n of a first cell, and to perform a procedure for transmitting a second physical uplink channel in subframe #n of a second cell, wherein if a sum of transmit power of the first physical uplink channel and transmit power of the second physical uplink channel exceeds a predetermined maximum transmit power set for the UE and if the first and second physical uplink channels include uplink control information (UCI) having same priority, a transmit power of one of the first and second physical uplink channels transmitted in a cell having a lower cell priority is reduced. - View Dependent Claims (7, 8, 9, 10)
