METHOD AND APPARATUS FOR SWITCHING CHANNEL CONFIGURATION FOR A RADIO BEARER

摘要

A method and apparatus for switching channel configurations for a radio bearer in a wireless communication system is disclosed. The wireless communication system supports one or more different channel types for transporting user data between a wireless transmit/receive unit (WTRU) and a network. The WTRU receives and stores several channel configurations for transport channels (TrCHs) and physical channels in the WTRU. The WTRU maps a radio bearer activating one of the stored channel configurations. Subsequently, the WTRU remaps the radio bearer activating another channel configuration among the stored channel configurations if it is determined that switching a channel configuration is favorable.
