    摘要: A method of performing hybrid automatic repeat request (HARQ) by a source station in a wireless communication system is provided. The method includes: transmitting data to a destination station at a transmission start time; receiving an acknowledgment (ACK) or negative-acknowledgement (NACK) signal for the data from the destination station after a first transmission time interval elapses from the transmission start time; and upon receiving the NACK signal, retransmitting the data after a second transmission time interval elapses from the transmission start time, wherein the second transmission time interval is one transmission time interval selected from a plurality of predetermined transmission time intervals. Accordingly, the wireless communication system can perform a heterogeneous HARQ process in which an HARQ period, an ACK/NACK transmission start time, and the like are different.

    摘要: A signal transmission method is provided, wherein, when a transmitter transmits a signal to a receiver, a transmitter processor multiplexes a plurality of data for a plurality of connections to be transmitted to one specific receiver, and constitutes a multiplexed medium access control (MAC) packet data unit (PDU) containing a MAC header part for receiving the multiplexed data, and a MAC PDU payload containing the multiplexed data, and the transmitter transmits the multiplexed MAC PDU to the specific receiver. The MAC header part includes a first header part containing a generic MAC header, and a second header part containing an extended header indicator serving as a 1-bit indicator for indicating the existence of an extended header (EH) for each flow ID for each of the plurality of connections. The MAC header part further includes a third header part which selectively contains the extended header for each flow ID in accordance with the extended header indicators for each flow ID.

    摘要: 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: 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.
