Abstract
Method and apparatus for a User Equipment (UE) determining a resource for a transmission of a control signal in response to a detected control channel including Control Channel Elements (CCEs) where transmission of the control signal is with a first sequence or with a second sequence if a first resource or a second resource is used respectively. The first resource is determined from the CCE index while the second resource is determined from a group of consecutive CCE indexes. The UE is also signaled a bit-map associating the subframe of the control channel detection with the use of a first resource or of a second resource.

Claim
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.
