摘要:
The present invention relates to a method and device for monitoring the control channel in a multicarrier system. Each of a plurality of sub-search spaces corresponds to each of a plurality of scheduled component carriers. The terminal monitors a downlink control channel for a scheduled component carrier corresponding to each of the plurality of sub-search spaces. Each of the plurality of sub-search spaces is defined displaced to the extent that they are offset from each other.

Provided are a synchronization acquisition method and apparatus in a multi-carrier system. A terminal acquires the synchronization for a first downlink component carrier by detecting a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in the first downlink component carrier. The terminal acquires the synchronization for a second downlink component carrier by detecting a reference signal in the second downlink component carrier.

Disclosed are a terminal device for receiving a signal in a wireless communication system for supporting a plurality of component carriers and a method thereof. In the terminal device for receiving the signal in the system for supporting the component carriers, a receiver receives a Physical Downlink Control Channel (PDCCH) including control information of a first type component carrier from a base station or a relay. A processor performs a decoding operation or controls an operation in a slip mode on the basis of control information included in a PDCCH in a second type component carrier after a time corresponding to a particular time offset value passes from a transmission time point of the PDCCH.

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.

摘要:
The present invention relates to a wireless communication system. Specifically, the invention relates to a method for configuring a component carrier at a base station in a wireless communication system, comprising the steps of determining whether initial access is permitted to a user equipment with respect to a downlink component carrier; and transmitting a synchronization channel signal and a broadcast channel signal to at least one user equipment via the downlink component carrier, wherein the initial access permission is applied to said at least one user equipment by modifying at least one of the synchronization channel signal and the broadcast channel signal.

摘要:
A method for identifying a MBSFN (Multimedia Broadcast multicast service Single Frequency Network) subframe at a user equipment (UE) in a wireless communication system is disclosed. Receiving module may receive receiving a subframe type information from an base station (BS). Receiving module may receive type information of the MBSFN subframe. The identifying module may identify an index of a MBSFN subframe based on the received subframe type information. The identifying module may identify a type of the MBSFN subframe based on the received type information of the MBSFN subframe. Decoding module may decode only a physical control channel region of the MBSFN subframe based on the identified type of the MBSFN subframe. Alternatively, Decoding module may decode the MBSFN subframe if the identified type of the MBSFN subframe is a decodable type or a known type.
