METHOD AND APPARATUS FOR PERFORMING DISCONTINUOUS RECEPTION OPERATION BY CONNECTED MODE USER EQUIPMENT IN A MOBILE COMMUNICATION SYSTEM

摘要

Methods and apparatuses are provided for establishing time alignment by a terminal in a mobile communication system. Information for identifying a preamble on a downlink control channel is received from a base station. The preamble is transmitted to the base station based on the information for identifying the preamble. A response message including timing adjustment information, information for a channel quality indicator (CQI) request, and uplink resource information on a downlink shared channel is received from the base station. The time alignment is established based on the timing adjustment information included in the response message. A CQI is transmitted based on the information for the CQI request and the uplink resource information.
