METHOD AND APPARATUS TO REDUCE RADIO RESOURCE OVERHEAD ASSOCIATED WITH INTERMITTENT DATA TRAFFIC

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for a No-TX mode for a wireless transmit/receive unit (WTRU) and a Node B that suspends transmission of power control update and associated signaling through dedicated uplink and downlink channels.SOLUTION: Triggers and signals between a WTRU and a Node B activate and disable a No-TX mode. A radio link is re-established to resume data transmission when the No-TX mode is disabled, and data may also be transmitted during defined transmission opportunities even in the No-TX mode.SELECTED DRAWING: Figure 1
