METHOD AND APPARATUS FOR SWITCHING CHANNEL CONFIGURATIONS FOR A RADIO BEARER

摘要

A method and apparatus (fig. 4) for switching channel configurations (#1 and #2) for a radio bearer (RB)in a wireless communication system is disclosed. The wireless communication system supports one or more different channel types (DPCH and HS-PDSCH) for transporting user data between a wireless transmit/receive unit (WTRU) and a network. The WTRU receives and stores several channel configurations (#1 and #2) for transport channels (TrCHs) and physical channels in the WTRU. The WTRU maps a radio bearer activating one (DPCH) f the stored channel configurations (#1 and #2). 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.
