Method for allocating resources for HARQ ACK/NACK signal transmission, and method and apparatus for HARQ ACK/NACK signal transmission using same

A resource allocation method comprising:

• transmitting higher layer signaling allocating a size k of resource sets used for transmission of a physical uplink control channel (PUCCH) to a mobile station (MS), to the MS;
• transmitting a physical downlink control channel (PDCCH) including transmission power control (TPC) information explicitly indicating a specific resource and at least one physical downlink shared channel (PDSCH) in the resource sets to the MS through at least one downlink component carrier;
• and
• receiving a Hybrid Automatic Repeat reQuest Acknowlegement/Not-Acknowlegement (HARQ ACK/NACK) signal with respect to the at least one physical downlink shared channel (PDSCH) mapped to the specific resource from the MS,
• wherein the size k is variably allocated according to a format of the physical uplink control channel (PUCCH) within a maximum number of resources that are allocated to the MS, and k is an integer greater than zero.

A mobile station (MS) comprising:

• a transceiver configured to receive higher layer signaling allocating a size k of resource sets used for transmission of a physical uplink control channel (PUCCH) to a mobile station (MS), from a base station (BS), to receive a physical downlink control channel (PDCCH) including transmission power control (TPC) information explicitly indicating a specific resource and at least one physical downlink shared channel (PDSCH) in the resource sets from the BS through at least one downlink component carrier;
• and to transmit a Hybrid Automatic Repeat reQuest Acknowlegement/Not-Acknowlegement (HARQ ACK/NACK) signal with respect to the at least one physical downlink shared channel (PDSCH) to the BS;
• a storage configured to store information associated with the higher layer signaling;
• and
• a controller configured to provide control to map the HARQ ACK/NACK signal to the specific resource,
• wherein the size k is variably allocated according to a format of the physical uplink control channel (PUCCH) within a maximum number of resources that are allocated to the MS, and k is an integer greater than zero.
