Abstract: A method is described for receiving a physical signal by a communication apparatus in a wireless communication system supporting carrier aggregation of a first component carrier and a second component carrier. The communication apparatus receives a physical downlink control channel (PDCCH) signal on the first component carrier. The communication apparatus also receives a physical downlink shared channel (PDSCH) signal corresponding to the PDCCH signal on the second component carrier. The first component carrier is different from the second component carrier.

Abstract: A method and device for transmitting a power headroom report (PHR) by a user equipment (UE) in a communication system supporting a plurality of carriers. The method includes transmitting, to an eNode B (eNB), a power headroom report (PHR) related to the plurality of carriers configured for the UE. The power headroom report (PHR) comprises a first type power headroom (PH) and a second type power headroom (PH). 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 only the primary carrier. The second type power headroom (PH) is calculated for case of simultaneous transmission of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH).
