    摘要: 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.

    摘要: Disclosed is a communication method in a multi-carrier system, including: allocating radio resources for transmitting signals to a middle guard band; and transmitting the signals through the radio resources; wherein the middle guard band is a frequency band positioned between used bands of a plurality of carriers, respectively, within an aggregated carrier formed by aggregating the plurality of carriers and a unit allocating the radio resources of the middle guard band is different from a unit allocating the radio resources of the used bands. A multi-carrier system uses the guard bands between the carriers to improve channel estimation performance or increase efficiency of radio resources.

    摘要: A method of transmitting control information in a carrier aggregation system is provided. The method includes: transmitting bandwidth information of a component carrier; configuring downlink control information including an additional indication field and an information field; mapping the downlink control information in any one of containing units having a plurality of predetermined different bit sizes in accordance with the bandwidth information; and transmitting the downlink control information mapped to any one of the containing units, wherein the information field is any one of a plurality of control information formats applicable to the component carrier, and the additional indication field includes information indicating a specific control information format to which the information field corresponds among the plurality of control information formats. Accordingly, the number of blind decoding attempts of a user equipment can decrease in a carrier aggregation system. Therefore, power consumption of the user equipment can decrease, and a decoding rate can increase.
