## Abstract

Disclosed is a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

## Claims

### Claim 1

A method of operating when a random access response is received, performed in a terminal, the method comprising:
receiving a random access response from a base station; and
adjusting uplink timing synchronization with the base station by using uplink timing synchronization information included in the random access response.
