METHOD AND APPARATUS FOR MANAGING UPLINK TIME ALIGNMENT

摘要

PURPOSE: An uplink time synchronization management method and apparatus thereof are provided to manage uplink time synchronization by receiving a random access response from a base station. CONSTITUTION: An RF(Radio Frequency) unit(63) receives a wireless signal. A processor(61) connects to the RF unit. The processor transmits a random access preamble for maintaining the uplink time synchronization. The processor receives a random access response from a base station. The random access response is a response for the random access preamble. [Reference numerals] (51,61) Processor; (52,63) RF unit; (53,62) Memory
