Abstract: Methods and apparatus are provided for determining acknowledgement/negative acknowledgement (ACK/NACK) resources at a user equipment (UE) in a wireless communication system. Control information is received on a downlink control channel for data transmission and the control information is decoded. It is determined whether a scheduling type of a data channel for the data transmission is persistent or non-persistent based on the decoded downlink control information. A resource for transmission of an ACK/NACK is determined based on the determined scheduling type of the data channel.

Abstract: Methods and apparatuses are provided for communication between a user equipment (UE) and a node B in a communication system. The UE generates a media access control protocol data unit (MAC PDU) including at least one field related to an amount of data, if the data becomes available for transmission. The MAC-PDU including the at least one field related to the amount of data is transmitted to the node B. Grant information is received from the node B. The data is transmitted to the Node B based on the grant information. Each of the at least one field related to the amount of data corresponds to a respective identifier.

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.
