Abstract: Disclosed is a method for performing a random access by a user equipment (UE), including identifying a path loss and a size of a message that the UE will transmit after a transmission of a preamble, selecting a preamble set from at least two preamble sets based on a first threshold and a second threshold, wherein a first preamble set is selected if the path loss is less than the first threshold and the size of the message is greater than the second threshold, wherein a second preamble set is selected if the path loss is greater than or equal to the first threshold, or the size of the message is less than or equal to the second threshold, selecting a preamble from the selected preamble set, transmitting, to a base station, the selected preamble, receiving, from the base station, a random access response message including resource allocation information in response to the transmission of the selected preamble, and transmitting, to the base station, a radio resource control message based on the resource allocation information.

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. Acknowledgement/negative acknowledgement (ACK/NACK) information for the data is transmitted to the base station. In case that the scheduling type is non-persistent, the ACK/NACK information is transmitted on a first resource determined according to a downlink control channel corresponding to the data. In case that the scheduling type is persistent, the ACK/NACK information for an initial persistent data transmission is transmitted on a second resource determined by using resource information received by high-layer signaling, and the ACK/NACK information for a persistent data retransmission is transmitted on a third resource determined according to the downlink control channel associated with the persistent data retransmission.

Abstract: A method and apparatus are provided for transmitting and receiving control information in a wireless communication system. A method in a base station includes identifying an offset value and a number of control channel candidates corresponding to a number of control channel elements (CCEs) constituting one control channel candidate; determining indexes of control channel candidates based on the identified offset value and the identified number of control channel candidates; and transmitting the control information to the terminal through at least one of the control channel candidates in a downlink control channel. The determined indexes of control channel candidates are spaced by a value determined based on the transmitted number of control channel candidates.

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.
