发明名称 RANDOM ACCESS METHOD AND APPARATUS OF UE IN MOBILE COMMUNICATION SYSTEM
摘要 A method and an apparatus for performing random access and uplink transmission of a User Equipment (UE) supporting Carrier Aggregation (CA) are provided. The method includes determining whether a Scheduling Request (SR) is pending, determining, when the SR is pending, whether an uplink transmission resource is available in a current Transmission Time Interval (TTI), determining, when the uplink transmission resource is not available, whether a Physical Uplink Control Channel (PUCCH) resource is configured for transmission of the SR, and initiating, when the PUCCH resource is not configured, a random access process in a primary cell. The random access method and apparatus of the present invention is advantageous to reduce the waste of transmission resources.
