Abstract: A method is provided for receiving a downlink control channel in a wireless communication system. A user equipment performs a blind decoding in a first search space on the cell to find a first Physical Downlink Control Channel (PDCCH). The user equipment receives a Radio Resource Control (RRC) message including information on a second search space for monitoring a second PDCCH and identity information, and performs a blind decoding in the second search space on the cell to find the second PDCCH. The first PDCCH is demodulated based on a physical cell identity of the cell, and the second PDCCH is demodulated based on the identity information instead of the physical cell identity.

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.

Abstract: A method is provided for receiving aperiodic channel state information (CSI). A base station (BS) transmits, to a user equipment (UE), an uplink downlink control information (DCI) format. The BS receives, from the UE, aperiodic CSI through a physical uplink shared channel (PUSCH) if the BS triggers an aperiodic CSI report using a CSI request field included in the uplink DCI format. The CSI request field is either a 1-bit field or a multi-bit field. When the UE is configured with only one cell, the 1-bit field is included in the uplink DCI. When the UE is configured with more than one channel state information-reference signal (CSI-RS), the multi-bit field is included in the uplink DCI.
