Claim:
1. A method for a user equipment (UE) to transmit a control signal using a first sequence or a second sequence in response to a detected control channel, the method comprising: identifying, through higher layer signaling, a configuration for the UE that informs about the first sequence; determining a resource for control signal transmission from a sum of a lowest control channel element (CCE) index of the detected control channel and either a first offset or a second offset based on the identified configuration; and transmitting the control signal in the resource using the first sequence or the second sequence based on the identified configuration, wherein the control signal is transmitted using the first sequence, if the configuration informs about the first sequence and a first resource, and wherein the first offset is UE-specific and the second offset is cell-specific.
