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.

Abstract: Methods and apparatuses are disclosed for providing control and data information in communication systems. A method performed by a user equipment (UE) in a wireless communication system includes identifying first offset information; determining a size of uplink data for the UE; and transmitting, to a base station in the wireless communication system, the uplink data with at least one of acknowledgement/non-acknowledgment (ACK/NACK) information and channel quality indicator (CQI) information on a physical uplink shared channel (PUSCH). A number of ACK/NACK repetition is determined based on the first offset information and the size of the uplink data.

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: Methods and apparatus are provided for a User Equipment (UE) configured to have multiple cells in a DownLink (DL) of a Time Division Duplex (TDD) communication system so as to determine a power of an acknowledgement signal that the UE transmits in a control channel and to determine a number of acknowledgement information bits that the UE multiplexes with data information bits in a data channel. A transmission power of the control signal is determined based on DL Assignment Index (DAI) Information Elements (IEs) in DL Scheduling Assignments (SAs) that the UE detects through multiple transmission time intervals and through the multiple configured DL cells. The number of acknowledgement information bits in the data channel is determined based on a DAI IE of an UpLink (UL) SA associated with the transmission of the data channel.

Abstract: Methods and apparatuses are described for transmitting acknowledgement information in a communication system. A method includes receiving one or more data TBs in one or more downlink data channels over TTIs; generating acknowledgement information comprising four acknowledgement bits, jointly representing a state of reception results for the plurality of data TBs, if the UE is configured for reception of the downlink data channels from two cells, a number of the TTIs is three or four, and a number of the data TBs is greater than a number of the acknowledgement bits; generating acknowledgement information respectively representing a reception result for each data TB by a corresponding acknowledgement bit, if the UE is configured for reception of the downlink data channels from a single cell or two cells, and a number of the TTIs is one or two; encoding the acknowledgement bits; multiplexing the encoded acknowledgement bits with uplink data; and transmitting the multiplexed acknowledgement bits and the uplink data on an uplink data channel.

Abstract: A method for receiving an acknowledgement signal by a base station in a wireless communication system and a base station are provided. The method includes transmitting information associated with transmission of a periodic channel quality indication (CQI) signal in an operating bandwidth; receiving a dynamic acknowledgement signal by using a first frequency resource in response to transmission of a downlink data signal, wherein a resource block (RB) allocated for the dynamic acknowledgement signal is determined based on the transmitted information; and receiving a periodic acknowledgement signal by using a second frequency resource in response to transmission of a downlink data signal, wherein the second frequency resource is allocated between the first frequency resource and a third frequency resource allocated for the periodic CQI signal.
