Method and device for triggering or reporting a scheduled request in wireless networks

A method for reporting an SR, a UE triggering an SR, the method comprising:

• the UE determining whether UL-SCH resource allocated for a first transmission is available in a current TTI;
• If yes, all SRs waiting for being processed being cancelled;
• if no, the SR being sent on an uplink control channel when it is determined that uplink control channel resource which can be used for sending an SR has been allocated to the UE, and that there is the uplink control channel resource which can be used for sending an SR in the current TTI and a maximum number of SR sending times is not reached.

A device for reporting an SR, comprising:

• a determining module, which is used for determining whether a UE has available UL-SCH resource allocated for a first transmission in a current TTI, and obtaining a determining result;
• a channel determining module, which is used for determining that uplink control channel resource that can be used for sending an SR has been allocated to the UE and there is the uplink control channel resource that can be used for sending an SR in the current TTI when the determining result of the determining module is no;
• an SR sending module, which is used for determining that a maximum number of SR sending times is not reached and sending an SR on an uplink control channel when there is the uplink control channel resource that can be used for sending an SR in the current TTI.
