    摘要: The present invention provides a method and device for effecting uplink HARQ (hybrid automatic repeat request) on a wireless communications system. A terminal receives HARQ setting data from a base station. If the terminal receives a NAC signal for an initial transmission block, the transmission characteristics of a retransmission block for the initial transmission block are adjusted on the basis of the HARQ setting data.

    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: The present invention relates to a method for monitoring a control channel and an apparatus thereof. A reference carrier is set, and then the multi-carrier sends blind decoding area information based on the reference carrier to monitor a control channel. A terminal monitors the control channel based on the blind decoding area information. The terminal performs blind decoding only for a component carrier required, and thus reduces power consumption and reception complexity.
