Methods and apparatus are described for a User Equipment (UE) to transmit and for a base station to receive a Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) signal in a resource of a Physical Uplink Control CHannel (PUCCH). The HARQ-ACK signal is transmitted from the UE in response to a detection of a PDCCH transmitted from the base station and conveying a DCI format that, depending on the PDCCH type, can include a HARQ-ACK PUCCH Resource Offset (HPRO) information field. The UE and the NodeB determine the PUCCH resource depending on the PDCCH type and, if the DCI format includes the HPRO, also depending on a PDCCH transmission type.
