Abstract:
1. A method for transmitting a power headroom report (PHR) by a user equipment (UE) in a communication system supporting a plurality of component carriers, the method comprising: transmitting, to an eNode B (eNB), a power headroom report (PHR) related to the plurality of component carriers configured for the UE, wherein the power headroom report (PHR) includes a first type power headroom (PH) and a second type power headroom (PH), wherein, while the first type power headroom (PH) is calculated for a power headroom report (PHR) related to a primary component carrier (PCC) and a non-PCC, the second type power headroom (PH) is calculated for a power headroom report (PHR) related to only the PCC, wherein the first type power headroom (PH) includes: wherein the second type power headroom (PH) includes a difference between (a) a value which is calculated using the PUSCH power value of the PCC and a physical uplink control channel (PUCCH) power value of the PCC and (b) the UE maximum output power value configured for the PCC.
