Patent ID: 8705397

Claim:
A method of transmitting signals at a user equipment (UE) of a wireless communication system, the method comprising: determining, by the UE, a first transmission (Tx) power P n of a physical uplink channel when transmission (Tx) timings of plural physical uplink channels coincide at a subframe, the plural physical uplink channels including the physical uplink channel; adjusting, by the UE the first Tx power P n to obtain a second Tx power P n ′ of the physical uplink channel; and transmitting, by the UE, the physical uplink channel using the second Tx power P n ′, wherein P n ′ is set as follows: if (P n −P MIN )>X, then P n ′ is set as P MIN +X, if (P n −P MIN )<=X, then P n ′ is set as P n , wherein P MIN is a minimum Tx power among Tx powers of the plural physical uplink channels, and X is a predetermined value, and wherein P n is not a maximum Tx power among the Tx powers of the plural physical uplink channels.
