Abstract: Methods and apparatus are provided for the transmission of physical downlink control signaling. In one method, a User Equipment (UE) receives information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) from a base station. Based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling, the UE determines a starting orthogonal frequency division multiple (OFDM) symbol on which EPDCCH transmission starts. The UE receives control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.

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

Abstract: A method apparatus and system for efficiently transmitting and receiving channels are provided in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM). A multiplexing scheme differs according to a channel when a transmitter transmits a packet data channel, a common control channel and a control channel designated for a particular user. Uncoded 1-bit information is broadly dispersed in frequency and time domains using multiplexing technology for maximizing diversity gain in a channel for transmitting information of at least one bit to a particular user like an acknowledgement (ACK) channel. The transmitter converts a sequence obtained by multiplexing multiple bits to be transmitted to a plurality of users to parallel signals, and broadly disperses the parallel signals in the time and frequency domains. When the uncoded 1-bit information is transmitted, reception reliability is improved because channel coding and transmission are efficiently performed using a small amount of resources.

Abstract: Methods and apparatuses are provided for wireless communication. First offset information and second offset information are identified. A size of uplink data for a user equipment (UE) is identified. The uplink data is transmitted 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 symbols for the ACK/NACK information is determined based on the first offset information and the size of uplink data. A number of symbols for the CQI information is determined based on the second offset information and the size of uplink data.

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.
