Abstract:
1. A method for a user equipment (UE) to dynamically transmit a control signal using a first sequence or a second sequence in response to a detected control channel including control channel elements (CCEs), the method comprising the steps of: assigning first resources, for transmissions of dynamic control signals using the first sequence, or second resources, for transmissions of dynamic control signals using the second sequence; determining a first resource in the first resources for the control signal transmission from a sum of a lowest CCE index of the detected control channel and a first offset if the first sequence is used; determining a second resource in the second resources for the control signal transmission from the sum of the lowest CCE index of the detected control channel and a second offset if the second sequence is used; and transmitting the control signal in the first resource or in the second resource.
