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).

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. A starting orthogonal frequency division multiplexing (OFDM) symbol for receiving the PDSCH signal is determined according to information received via a radio resource control (RRC) signal.

Abstract: Disclosed are a repeater for receiving signals from a base station in a wireless communication system, and a signal receiving method. The base station reports, to each repeater, information on the aggregation level of a relay-control channel element (R-CCE) of a relay-physical downlink control channel (R-PDCCH) via an explicit signaling method or implicit signaling method. In the event the base station reports via an explicit signaling method, the repeater receives, from the base station, information on the aggregation level of R-CCE which is a transmission unit of R-PDCCH, wherein the information contains control information for the repeater. Then, the repeater decodes an R-PDCCH region on an R-CCE aggregation level basis in accordance with the received R-CCE aggregation level information.

Abstract: A method for transmitting, by a base station, signals in a communication system. Control information for a subsidiary carrier band is transmitted to a mobile station via a primary carrier band. Data is transmitted to the mobile station via the subsidiary carrier band based on the control information and via the primary carrier band. Furthermore, the primary carrier band is a carrier frequency band which the mobile station initially attempts to access or via which information of a carrier aggregation configuration is transmitted. Additionally, the control information includes a logical index assigned to the subsidiary carrier band for the mobile station and a physical index of a frequency allocation band used as the subsidiary carrier band. The physical index corresponds to one of plural absolute frequency band indexes assigned to frequency allocation bands available in the communication system.
