A method of receiving a control signal by a user equipment in a wireless communication system is disclosed. The present invention includes receiving control regions including the control channel relevant to each of a plurality of component carriers via a plurality of component carriers and detecting the control channel for the user equipment by performing blind decoding by a unit of CCE (control channel element) aggregated at a preset level in a search space included in the control regions. And, start positions of the search spaces in the plurality of component carriers is in a certain relationship. Moreover, the preset level is identically set for each of the plurality of component carriers.

The present invention relates to a wireless communication system supporting carrier aggregation. More specifically, the present invention relates to a method in which a terminal transmits ACK/NACK and to a device therefor; and relates to a method comprising the steps of: receiving one or more items of data simultaneously on a plurality of carriers; generating an ACK/NACK payload comprising one or more items of ACK/NACK information about the one or more items of data; and transmitting the ACK/NACK payload, wherein the position of each item of ACK/NACK information in the ACK/NACK payload corresponds to respective carriers, and the present invention relates to a device for the method.
摘要:
A method and apparatus for requesting uplink resources in a wireless communication system is provided. A user equipment determines whether a scheduling request for requesting uplink resources is triggered. If the scheduling request is triggered, the user equipment transmits a first set of frequency domain sequences and a second set of frequency domain sequences in a subframe.

A method of transmitting uplink control signals in a wireless communication system includes preparing a ACK/NACK resource for transmitting the ACK/NACK signal for HARQ of downlink data on an uplink control channel, preparing a scheduling request resource for transmitting a scheduling request and the ACK/NACK signal on the uplink control channel in one subframe, and transmitting the ACK/NACK signal on the uplink control channel configured by the scheduling request resource for the positive transmission of the scheduling request and transmitting the ACK/NACK signal on the uplink control channel configured by the ACK/NACK resource for negative transmission of the scheduling request.
摘要:
A method of transmitting a scheduling request which is used to request a radio resource for uplink transmission includes configuring an uplink control channel for transmission of a scheduling request in a subframe, the subframe comprising two consecutive slots, a slot comprising a plurality of single carrier-frequency division multiple access (SC-FDMA) symbols, the scheduling request being carried by presence or absence of transmission of the uplink control channel, and transmitting the scheduling request on the uplink control channel.
