APPARATUS FOR PERFORMING UPLINK SYNCHRONIZATION IN MULTIPLE COMPONENT CARRIER SYSTEM AND METHOD THEREFOR |
摘要 |
There are provided an apparatus for performing uplink synchronization in a multiple component carrier system and a method thereof. The method includes determining whether a timing advance value for adjusting uplink timing of a secondary serving cell is valid, entering a transmission holding mode in which the secondary serving cell holds uplink transmission, and determining a releasing condition of releasing the transmission holding mode is satisfied. The timing advance value is secured and the validity of the timing advance value is determined so that it is possible to prevent uplink interference from being generated due to a difference in timing advance values and to prevent capability from deteriorating due to the uplink interference. |
