HARQ-ACK signal transmission in response to detection of control channel type in case of multiple control channel types
First Claim
1. A method of a user equipment (UE) for transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) signal on a physical uplink control channel (PUCCH), the method comprising:
- receiving, by the UE, downlink control information (DCI) on a physical downlink control channel (PDCCH) using control channel elements (CCEs), wherein the DCI comprises a HARQ-ACK PUCCH resource offset (HPRO) information field;
determining, by the UE, a PUCCH resource, nPUCCH, as nPUCCH=nECCE+f(HPRO)+NPUCCHE, wherein nECCE is a first CCE of the CCEs used for receiving the DCI on the PDCCH, f(HPRO) is a mapping function that provides an integer based on the HPRO information field, and NPUCCHE is an offset assigned to the UE from a base station via higher layer signaling; and
transmitting, by the UE, the HARQ-ACK signal associated with the DCI based on the determined PUCCH resource.

Abstract
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.
