Abstract: A method for transmitting uplink signals, which include ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals, is disclosed. The method comprises serially multiplexing the control signals and the data signals; sequentially mapping the multiplexed signals within a specific resource region in accordance with a time-first mapping method, the specific resource region including a plurality of symbols and a plurality of virtual subcarriers; and arranging the ACK/NACK signals at both symbols near symbols to which a reference signal of the plurality of symbols is transmitted. Thus, the uplink signals can be transmitted to improve receiving reliability of signals having high priority.

Abstract: A method of performing HARQ performed by a user equipment (UE) is provided. The method includes receiving a bundling indicator which indicates the number of bundled downlink subframes, determining whether at least one bundled downlink subframe is missed by comparing the bundling indicator with the number of detected bundled downlink subframes, generating a representative ACK/NACK signal when no bundled downlink subframe is missed, and transmitting the representative ACK/NACK signal on an uplink channel. Recovery capability is maximized and the packet loss is reduced in such a situation that less number of ACK/NACK signals are fed back than that of downlink packets.

Abstract: A user equipment receives configuration information from a base station in a wireless communication system. Radio signals carrying configuration control information are received by a user equipment (UE) that includes an ACK/NACK feedback mode indicator. The UE also receives downlink subframes. The ACK/NACK feedback mode indicator is processed to determine if the ACK/NACK feedback mode indicator indicates the user equipment should (a) send an ACK/NACK signal in a one-to-one mapping between a downlink subframe and a corresponding uplink ACK/NACK signal or (b) send an ACK/NACK signal in an N-to-one mapping between N downlink subframes, where N is an integer greater than one, and a corresponding single uplink ACK/NACK signal. One or more ACK/NACK signals is transmitted in accordance with the determination of the processor.

Abstract: Methods and apparatus for performing HARQ performed by a user equipment (UE) are provided. A bundling indicator is received which indicates the number of bundled downlink subframes, and a determination is made whether at least one bundled downlink subframe is missed by comparing the bundling indicator with the number of detected bundled downlink subframes. A representative ACK/NACK signal is generated when no bundled downlink subframe is missed, and the representative ACK/NACK signal is transmitted on an uplink channel. Recovery capability is maximized and packet loss is reduced so that fewer ACK/NACK signals are fed back than downlink packets.
