Method for triggering scheduling information report in enhanced dedicated channel and user equipment

The invention relates to triggering method and user set used to increase dispatching information message in special channel to reduce unnecessary periodicity SI message, increase wireless resource utilization level. While the MAC-e PDU is carrying the SI because of surplus bit number D is not less than 18, the timer of periodically triggering SI message will be newly start-up. In addition, the timer includes T-SING one under the state that the user set doesn't be allowed to transmit data and the T-SIG one under the opposite state.
