    摘要: Disclosed is a method for transmitting a sounding reference signal from a terminal to a base station in a radio communication system. More specifically, the method comprises the steps of: receiving downlink control information from a base station; checking a flag bit included in said downlink control information; checking an interpretation bit is included in said downlink control information, when said flag bit indicates an uplink; and transmitting an additional sounding reference signal and/or an uplink common channel based on said interpretation bit.

    摘要: The present invention provides a method and apparatus for performing a HARQ in a wireless communication system. In the method for performing a HARQ according to the present invention, a terminal transmits an uplink data over a PUSCH (Physical Uplink Shared Channel); and receives an ACK/NACK (Acknowledgement/Non-Acknowledgement) signal over a Physical Hybrid-ARQ Indicator Channel (PHICH) corresponding to the PUSCH, with the signal indicating whether the uplink data is received through a plurality of layers. Here, downlink resources to which a PHICH is mapped for each of the plurality of layers do not overlap each other. Those downlink resources to which a PHICH is mapped for each of the plurality of layers can be determined based on different cyclic shift values that are allocated to the plurality of the layers, respectively.

    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.
