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:
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.

The present invention relates to a method and to an apparatus for random access in a wireless communication system to which carrier aggregation is applied. According to one aspect of the present invention, a method in which a base station supports random access of a terminal in a wireless communication system that supports carrier aggregation, comprises a step in which the base station allocates, to the terminal, a dedicated PRACH preamble for a second random access in an uplink component carrier (hereinafter, referred to as UL CC) which is additionally allocated or the configuration of which is changed after a first random access, and receives the dedicated PRACH preamble from the terminal.
摘要:
A wireless device and method for a multiple carrier system are provided. The wireless device comprises a carrier management unit for determining at least one of a plurality of carriers as a reference carrier for monitoring a control channel and a control channel unit for monitoring the control channel over the reference carrier, wherein the carrier management unit switches the reference carrier to at least one of remaining carriers of the plurality of carriers. Accordingly, control channel traffic can be prevented from concentrating on a particular carrier, and a diversity gain can be achieved.
