我看标准上说-
if no UL-SCH resources are available for a transmission in this TTI:
- if the UE has no valid PUCCH resource for SR configured in any TTI: initiate a Random Access procedure (see subclause 5.1) on the PCell and cancel all pending SRs;
- else if the UE has a valid PUCCH resource for SR configured for this TTI and if this TTI is not part of a measurement gap and if sr-ProhibitTimer is not running:
- if SR_COUNTER < dsr-TransMax:
- increment SR_COUNTER by 1;
- instruct the physical layer to signal the SR on PUCCH;
- start the sr-ProhibitTimer.
请问具体什么时候要通过随机接入的方式发送SR？上面的in any TTI怎么理解？
