    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: A method and an apparatus method are provided for transmitting uplink information in a Single Carrier Frequency Division Multiple Access (SC-FDMA) wireless communication system. The method includes determining whether Acknowledgement/Negative Acknowledgement (ACK/NACK) information indicating whether or not downlink data has been received exists to be transmitted, if uplink data exists to be transmitted; multiplexing the uplink data and control information for the uplink data and transmitting multiplexed data including the uplink data and the control information, through a frequency resource allocated for the uplink data, if no ACK/NACK information exists; and multiplexing the uplink data, the control information for the uplink data, and the ACK/NACK information, and transmitting multiplexed data through the frequency resource allocated for the uplink data, if the ACK/NACK information exists. The ACK/NACK information is located adjacent to a pilot for the uplink data.

    Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz˜100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The wireless system deployed in mmWave/cmWave system is expected to employ DL beam sweeping on broadcast control information to provide cell coverage to the UE which would result in excessive signaling overhead.

    Abstract: Methods and apparatus are provided in which data is received from a base station on a downlink data channel. It is determined whether a scheduling type of the downlink data channel is persistent or non-persistent. In case that the scheduling type is non-persistent, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on a first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on the first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is persistent data following the initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource determined based on a second ACK/NACK resource allocation scheme.

    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 is provided for communication between a UE and a Node B in a communication system. The UE generates a Media Access Control-Protocol Data Unit (MAC-PDU) including a first field related to at least one queue ID and a second field related to at least one amount of data to be transmitted, where the data to be transmitted has its priority. The MAC-PDU including the first and second fields is transmitted to the Node B. Grant information is received from the Node B. Data is transmitted to the Node B based on the grant information and the priority. One amount of data in the second field corresponds to one queue ID in the first field.
