    Abstract: A method and apparatus are provided for transmitting a synchronization signal for cell search in an Orthogonal Frequency Division Multiplexing (OFDM) communications system. The method includes identifying a primary synchronization sequence; identifying a secondary synchronization sequence associated with a cell identifier; mapping the primary synchronization sequence based on center subcarriers in a first OFDM symbol; mapping the secondary synchronization sequence based on the center subcarriers in a second OFDM symbol; transmitting the mapped primary synchronization sequence in the first OFDM symbol; and transmitting the mapped secondary synchronization sequence in the second OFDM symbol. The second OFDM symbol is adjacent to the first OFDM symbol, and the center subcarriers are part of a system bandwidth and a part of the center subcarriers is not used for mapping the secondary synchronization sequence.

    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: A method is provided for transmitting uplink control information by a terminal in a cellular communication system. The method includes receiving system information associated with uplink transmission of a Sounding Reference Signal (SRS) from a base station; determining an orthogonal sequence having a first length or a second length predefined; transmitting uplink control information to which a first orthogonal sequence is applied, if the first orthogonal sequence having the first length is determined; and transmitting uplink control information to which a second orthogonal sequence is applied, if the second orthogonal sequence having the second length is determined. The SRS is selectively transmitted with the uplink control information, based on the received system information, and the uplink control information, to which the first orthogonal sequence having the first length is applied, is transmitted regardless of whether or not the SRS is transmitted in a corresponding slot.
