摘要:
Disclosed is a method for setting a carrier indication field indicating an element carrier in a multi-carrier system using a plurality of element carriers. The method includes: transmitting a value of a carrier indication field (CIF) and first CIF setting information that indicates a first mapping relationship between element carriers; transmitting downlink control information (DCI) including a carrier indication field; and transmitting a value of a CIF and second CIF setting information that indicates a second mapping relationship between element carriers, wherein the carrier indication field is a field indicating any one of the plurality of element carriers, and at least one element carrier is mapped with the same carrier indication field value in the first and second mapping relationships.

The present invention relates to a method in which a terminal transmits uplink control information in a wireless communication system using multiple carriers. The method comprises the following steps: receiving, from a base station, indication information that indicates whether or not to use multiple uplink control resources; determining a first uplink control resource on the basis of a specific control channel element (CCE) index of the CCE received from the base station; and, if the indication information indicates to use multiple uplink control resources, applying a predetermined rule to the specific CCE index to determine a second uplink control resource.

The present invention relates to a method in which a terminal transmits a sounding reference signal in a wireless communication system. Specifically, the method includes: receiving sounding reference signal setting information from a base station; and transmitting the sound reference signal to the base station on the basis of the sounding reference signal setting information, wherein an upstream link signal based on the sounding reference signal is transmitted over an upstream link control channel, and a frequency band corresponding to an upstream link data channel and a frequency band corresponding to an upstream link control channel are allocated as frequency resources for the sounding reference signal.

Provided are an apparatus and method of performing an uplink hybrid automatic repeat request (HARQ) in a wireless communication system. A terminal transmits a transport block to a base station via a physical uplink shared channel (PUSCH) using uplink resource allocation and receives an ACK/NACK signal for the transport block from the base station via a physical hybrid-ARQ indicator channel (PHICH). A PHICH resource used for transmitting the PHICH is identified from a PUSCH resource used for transmitting the PUSCH, and the PUSCH resource is mapped to the PHICH resource according to an uplink element carrier through which the transport block is transmitted.

The present invention relates to a wireless communication system, and more particularly, discloses a method and apparatus in which a relay allocates carriers on a backhaul link and an access link in a multi-carrier wireless communication system. The method in which the relay allocates resources in a multi-carrier wireless communication system in accordance with one embodiment of the present invention, comprises: determining a subframe pattern allocated on a first uplink component carrier to enable a backhaul uplink transmission from the relay to a base station; determining a subframe requiring reception of an access uplink from user equipment to the relay on the first uplink component carrier in accordance with a synchronous HARQ operation; and transmitting resource allocation control information containing carrier switching indicating information to the user equipment in the event the subframe requiring reception of an access uplink is determined to be the same as the subframe allocated for backhaul uplink transmission on the first uplink component carrier.
