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: 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.
