METHOD AND APPARATUS FOR HANDLING UPLINK TRANSMISSION START IN WIRELESS COMMUNICATIONS SYSTEM

摘要

A method for processing an uplink transmission start in a wireless communication system and an apparatus thereof are provided to enable a user terminal to use an absolute grant value set by the secondary absolute grant information due to making a serving grant value influenced by the secondary absolute grant information if a variable of primary_grant_available is set to "false" in case that an upper layer does not provide serving grant value information elements and the primary and secondary grant selector information elements when transmission starts in an E_DCH(Enhanced Dedicated Channel). A method for processing an uplink transmission start in a wireless communication system comprises the following several steps. The uplink transmission starts(300). It is expressed that a serving grant value can be influenced by the secondary absolute grant information by setting a variable of primary_grant_available with "false" in case that one specific information element is not received(302). The uplink transmission is terminated(304).
