A method includes transmitting a random access preamble, receiving a random access response as a response of the random access preamble, wherein the random access response comprises an uplink resource assignment and a request for transmission of a Channel Quality Indicator (CQI), and transmitting the CQI in the uplink resource assignment.

Method of performing random access procedure in wireless communication system

A method of a user equipment performing random access in a multi-carrier system comprises receiving mapping information through downlink component carriers, sending a random access preamble through uplink component carriers, and receiving a random access response through a specific downlink component carriers determined based on the mapping information.

Method and apparatus for performing random access in a multi-carrier system

A method for transmitting an uplink control signal includes receiving scheduling information for transmission of the uplink control signal, and transmitting the uplink control signal according to the scheduling information. Various control signals can be transmitted without interference with other control signals while maintaining a single carrier property.

Method for transmitting uplink control signal

A method of controlling a transmit power of an uplink channel is provided. Downlink control information of which Cyclic Redundancy Check (CRC) parity bits are masked with a TPC identifier is received on a downlink control channel. The transmit power of the uplink channel is adjusted based on a TPC command in the downlink control information.

Method of controlling transmit power of uplink channel

A multimode mobile terminal and communication method thereof are discussed, by which communication is enabled using various networks. The method according to an embodiment includes a display unit configured to display a plurality of currently available networks detected by the terminal, each network being a different network type, a user input unit configured to generate a selection signal for a specific network of the plurality of currently available networks in response to a user input, a controller operatively connected to the display unit and user input unit and configured to control communication carried out via the specific network selected via the user input unit, and a wireless communication unit operatively connected to the controller and configured to carry out the communication via the specific network.

Multi-mode mobile terminal and communication method for manual network selection

A method of controlling transmission power in a wireless communication system includes allocating persistent radio resources, and transmitting transmission power control information multiplexed with data via a data channel according to the persistent resources. Transmission power can be simply controlled without reducing the capacity of a control channel according to persistent scheduling.
