Terminal device for transmitting a power headroom report in a multi-carrier communication system, and method for same

A user equipment for transmitting a power headroom report (PHR) in a communication system supporting a plurality of carriers, the user equipment comprising:

• a transmitter configured to transmit, to the eNode B, a power headroom report (PHR) related to the plurality of carriers configured for the UE,
• wherein the power headroom report (PHR) comprises 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 carrier and a non-primary carrier, the second type power headroom (PH) is calculated for a power headroom report (PHR) related to the primary carrier other than the non-primary carrier,
• wherein the first type power headroom (PH) is calculated for a physical uplink shared channel (PUSCH) transmission,
• wherein the second type power headroom (PH) is calculated for a simultaneous transmission of a physical uplink control channel (PUCCH) and the PUSCH,
• wherein the power headroom report (PHR) further comprises information indicating at least one carrier index related to the first type power headroom (PH),
• wherein a maximum UE output power is configured per carrier, the second type power headroom (PH) is calculated based on a maximum UE output power for the primary carrier, and
• wherein the power headroom report (PHR) is transmitted as a type of MAC Control Element.

A method for receiving a power headroom report (PHR) by an eNode B in a communication system supporting a plurality of carriers, the method comprising:

• receiving, to the eNode B, a power headroom report (PHR) related to the plurality of carriers configured for the UE,
• wherein the power headroom report (PHR) comprises 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 carrier and a non-primary carrier, the second type power headroom (PH) is calculated for a power headroom report (PHR) related to the primary carrier other than the non-primary carrier,
• wherein the first type power headroom (PH) is calculated for a physical uplink shared channel (PUSCH) transmission,
• wherein the second type power headroom (PH) is calculated for a simultaneous transmission of a physical uplink control channel (PUCCH) and the PUSCH,
• wherein the power headroom report (PHR) further comprises information indicating at least one carrier index related to the first type power headroom (PH),
• wherein a maximum UE output power is configured per carrier, the second type power headroom (PH) is calculated based on a maximum UE output power for the primary carrier, and
• wherein the power headroom report (PHR) is transmitted as a type of MAC Control Element.
