摘要:
The present invention relates to a method and device for monitoring the control channel in a multiple carrier system. A terminal determines an extended search space comprising a plurality of sub-search spaces, and each of the plurality of sub-search spaces corresponds to at least one of a plurality of scheduled component carriers. The terminal monitors a downlink control channel for the scheduled component carrier corresponding to each of the plurality of sub-search spaces. At least one of the plurality of sub-search spaces is a shared sub-search space corresponding to at least two of the plurality of scheduled component carriers.

A method and apparatus of transmitting a reference signal in a wireless communication system is provided. Demodulation Reference Signals (DMRSs) for a plurality of respective antennas is generated. The DMRSs are mapped to a resource region, and transmitted through the respective corresponding antennas. The DMRSs are multiplexed using at least one of frequency division multiplexing (FDM), code division multiplexing (CDM), and time division multiplexing (TDM) methods and mapped in the resource region. Also, a position of an orthogonal frequency division multiplexing (OFDM) symbol to which the DMRSs are mapped in the resource region is an OFDM symbol to which a physical downlink control channel (PDCCH) and a legacy cell-specific reference signal (CRS) are not mapped.

A method and apparatus for transmitting data performed by at least one base station (BS) in a wireless communication system is provided. First signals are respectively mapped to a first Orthgonal Frequency Division Multiplexing (OFDM) symbol of a first BS and a second BS, and are transmitted. A second signal, having a θ shifted phase of the first signal, is mappped to a second OFDM symbol, and is transmitted by the first BS. The respective first signals and the second signal are transmitted in a same subcarrier in a frequency domain.

A method of transmitting broadcasting information or system information to user equipments in an idle mode or a sleep mode in a radio access system is disclosed. The method of transmitting broadcasting information to a user equipment in an idle mode includes receiving information related to the idle mode, decoding a control channel assigned to a first paging subframe according to the information related to the idle mode, and receiving the broadcasting information via a second paging subframe indicated by the control channel regardless of the information related to the idle mode, if the decoding of the control channel is successful.

Disclosed are a base station apparatus and a repeater apparatus for transceiving signals in a wireless communication system. The repeater apparatus comprises: a receiver which receives a signal from a base station through a first region of a first downlink subframe in a component carrier that supports first and second wireless communication schemes; and a transmitter which transmits, through a second region of the first downlink subframe, a signal to one or more terminals of one or more first type of terminals which use the first wireless communication scheme and one or more second type of terminals which use the second wireless communication scheme, simultaneously with said reception of the signal. Here, the first region and the second region are multiplexed in the first downlink subframe in accordance with a frequency division multiplexing (FDM) scheme.

Provided are a cell searching method and an apparatus in a multi-carrier system. A terminal acquires a first physical cell identity (PCI) for a first downlink component carrier, and acquires an expanded PCI for a second downlink component carrier. A first downlink reference signal through the first downlink element carrier is transmitted on the basis of the PCI, and a second downlink reference signal through the second downlink component carrier is transmitted on the basis of the expanded PCI.

Disclosed are an apparatus and method for transmitting/receiving control information in a wireless communication system that supports carrier aggregation. According to the present invention, a processor of a base station device that transmits control information configures a component carrier type for each of a plurality of downlink component carriers (DL CCs) in accordance with whether or not each of the plurality of DL CCs can support a relay PDCCH (R-PDCCH), which is a downlink control channel dedicated to a relay node. A transmitting antenna transmits information on the type of each of the configured DL Cs to the relay node.
