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.

Disclosed is a terminal device for transmitting a power headroom report (PHR) in a multi-carrier communication system, and a method for same. The terminal device for transmitting a power headroom report (PHR) in a multi-carrier communication system comprises a transmitter and a processor. The transmitter transmits, to a base station, a power headroom report for one or more active component carriers allocated to user equipment from among multiple carriers. The processor controls the transmitter such that the transmitter transmits the power headroom report including a first type of power headroom information calculated using the power value of a physical uplink shared channel (PUSCH) of the main component carrier among the active component carriers, and a second type of power headroom information calculated using the power value of the PUSCH and the power value of a physical uplink control channel (PUCCH) of the main component carrier.

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.
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.
