Abstract: Methods and User Equipment (UE) apparatuses are provided for transmitting Reference Signals (RSs). A method includes receiving a cell-specific sequence-hopping parameter; receiving a UE-specific sequence-hopping parameter; determining a reference signal sequence based on the UE-specific sequence-hopping parameter; and transmitting the reference signal based on the determined reference signal sequence. Sequence hopping does not apply to the reference signal sequence if the cell-specific sequence-hopping parameter indicates that the sequence hopping is enabled and the UE-specific sequence-hopping parameter indicates that the sequence hopping is disabled.

Abstract: Methods and apparatuses are provided for determining a resource for an acknowledgement signal in a wireless communication system. A transceiver of a user equipment (UE) receives a parameter associated with one or more resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth. A controller of the UE determines an RB for transmission of the acknowledgement signal, based on the parameter. The transceiver transmits the acknowledgement signal on the determined RB. The RB for the transmission of the acknowledgement signal is not more outer than the one or more RBs for periodic transmission of the CQI signal in the operating bandwidth.

Abstract: A device and method for handling HARQ feedback in a mobile communication system are disclosed. The HARQ feedback handling method includes: analyzing a control message from a base station to recognize presence of HARQ feedback relationships between downlink carriers and uplink carriers; determining an uplink carrier (a downlink carrier) to support HARQ feedback in response to downlink traffic (uplink traffic) sent through a downlink carrier (an uplink carrier); and sending (receiving) HARQ feedback through the determined uplink carrier (downlink carrier).
