  • Patent number: 9178670
    Abstract: In the transmission of user data for a user equipment and control information on the user data to the user equipment using a plurality of carrier waves by a base station in a wireless communication system, the control information can be transmitted over a portion of the plurality of carrier waves, and carrier waves over which only the user data is transmitted can be generated without the control information. Here, the base station transmits, at a certain number of subframes following the subframes at which the control information is transmitted, the user data over the carrier waves to which only the user data is allocated. Thus, the user equipment can minimize the buffering of the user data during the detection of the control information, and decode the user data.

  • Publication number: 20150146609
    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.
