The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus in which a base station transmits a signal to a relay in a wireless communication system. A method in which a terminal receives a downlink signal in a wireless communication system that supports carrier aggregation comprises: a step of receiving, on a first carrier, a physical downlink control channel (PDCCH) having no carrier indication information; and a step of receiving a physical downlink shared channel (PDSCH) using the scheduling information carried on the PDCCH, wherein the PDSCH is received on the first carrier in the event the PDCCH is a non-semi-persistent scheduling (SPS) PDCCH, and the PDSCH is received on a second carrier different from the first carrier in the event the PDCCH is an SPS PDCCH.

The present invention relates to a method and apparatus in which a base station transmits a physical ARQ channel (PHICH) in a wireless communication system. More particularly, the present invention relates to a method and apparatus for transmitting a PHICH, wherein the method comprises the following steps: generating a plurality of hybrid of ARQ (HARQ) indicators: channel-coding the plurality of HARQ indicators into a single HARQ codeword; and transmitting the HARQ codeword via the PHICH, wherein the value of a portion of the HARQ codeword indicates individual value of each of HARQ indicators, and the value of the rest of the HARQ codeword indicators a value of joint operation of the plurality of HARQ indicators.
摘要:
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving a physical downlink control channel (PDCCH); receiving a physical downlink shared channel (PDSCH) indicated by the PDCCH; and transmitting ACK/NACK for the PDSCH via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the number of aggregated carriers into account.
