Abstract: A method and an apparatus method are provided for transmitting uplink information including acknowledgement information in a wireless communication system. The method includes determining whether transmission of acknowledgement information overlaps with transmission of uplink data in a time domain; multiplexing the uplink data and the acknowledgement information, in case that the transmission of the acknowledgement information overlaps with the transmission of the uplink data in the time domain; and transmitting the multiplexed uplink data and acknowledgement information to a base station. The acknowledgement information is located adjacent to a pilot for the uplink data, and the pilot is used for demodulation of the uplink data.

Abstract: A method and an apparatus method are provided for transmitting uplink information including acknowledgement information in a wireless communication system. The method includes coding, by a terminal, uplink data and the acknowledgement information by using different coding schemes respectively; multiplexing, by the terminal, the coded uplink data and the coded acknowledgement information into the uplink information; and transmitting, by the terminal, the uplink information using resources. At least a portion of the uplink data is transmitted based on a first resource and the acknowledgement information is transmitted based on a second resource. The first resource and the second resource are adjacent to each other with respect to a time domain and a frequency domain. The acknowledgement information is located immediately adjacent to a pilot for the uplink data, and the pilot is used for demodulation of the uplink data.

Abstract: Methods and apparatuses are provided for transmitting a signal using a sequence in a wireless communication system. A first sequence used to transmit a first signal in a first channel is determined by performing group-hopping using a pseudo-random pattern over a first group of sequences. A second sequence used to transmit a second signal in a second channel is determined by performing the group-hopping using the pseudo-random pattern over a second group of sequences.

Abstract: Methods and apparatuses are provided for wireless communications. Configuration information comprising a resource start offset is received. Downlink control information (DCI) transmitted using a first antenna port of a base station is received on an enhanced physical downlink control channel (EPDCCH) using at least one of control channel elements (CCEs). A resource of a physical uplink control channel (PUCCH) is determined based on a first CCE of the at least one of the CCEs, the first antenna port, information in the DCI, and the resource start offset in the configuration information, in response to a transmission type of the EPDCCH being localized transmission. A hybrid automatic repeat request acknowledgement (HARQ-ACK) signal is transmitted on the resource to the base station

Abstract: Methods and apparatuses are described for transmitting acknowledgement information in response to a plurality of data TBs received on one or more downlink data channels over TTIs by a UE in a TDD communication system. A method includes generating acknowledgement information comprising four acknowledgement bits, jointly representing a state of reception results for the plurality of data TBs, if a first condition applies, wherein 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 a second condition applies; 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: Methods and apparatuses are provided for transmitting a set of acknowledgement (ACK) bits, by a user equipment (UE). A first subset of ACK bits is transmitted. A second subset of ACK bits is transmitted. The first subset of ACK bits is a response to a reception of one or more scheduling assignments (SAs) for a first cell group, and the second subset of ACK bits is a response to a reception of one or more SAs for a second cell group. The first subset of ACK bits is different from the second subset of ACK bits. A union of the first subset of ACK bits and the second subset of ACK bits is the set of ACK bits that the UE transmits in a subframe.
