Abstract:
1. A method of reducing transmission power, the method performed by a user equipment and comprising: performing maximum power reduction (MPR) on maximum output power for transmission with non-contiguous resource allocation in a single component carrier; and transmitting a signal based on the MPR, wherein the MPR is performed differently depending on a resource allocation ratio A, wherein the resource allocation ratio A is defined as a ratio between N RB agg and N RB alloc , wherein the N RB agg is a channel band represented as the number of resource blocks (RBs), and the N RB alloc represents the total number of RBs simultaneously transmitted, wherein the MPR is determined according to a following equation: MPR=CEIL {M A , 0.5}, the CEIL is a function of rounding up by 0.5, and wherein the M A is a value determined according to following equations: M A =(8.0-10.12*A) when 0<A≦0.33, M A =(5.67-3.07*A) when 0.33<A≦0.77, and M A =(3.31) when 0.77<A≦1.0.
