Abstract: Methods and apparatuses are provided for establishing time alignment by a User Equipment (UE) in a wireless communication system. Information for identifying a dedicated preamble on a downlink control channel is received from a base station. The dedicated preamble is transmitted to the base station based on the information. A response message to the transmitted dedicated preamble is received from the base station on a downlink shared channel. The response message includes a timing adjustment information and information for a Channel Quality Indicator (CQI) report. Time alignment is established based on the timing adjustment information included in the response message. The CQI report based on the information for CQI report is transmitted to the base station.

Abstract: A signal transmission method and apparatus of a user equipment for a mobile communication system is provided for improving data transmission reliability and efficiency by transmitting data based on precise discrimination of the uplink transmission resource assignment messages indicative of initial transmission and retransmission. A signal transmission method of a user equipment for a mobile communication system receives an uplink transmission resource assignment message from a base station determines whether a Hybrid Automatic Repeat reQuest (HARQ) buffer is empty, and when the HARQ buffer is empty, transmits to the base station a Media Access Control Protocol Data Unit (MAC PDU) generated with reference to information contained in the uplink transmission resource assignment message.
