Apparatuses, methods, and systems are disclosed for efficiently transmitting a SR. One apparatus includes a memory comprising instructions executable by a processor to cause the apparatus to trigger a buffer status report for a first logical channel and trigger a SR for the first logical channel based at least in part on the triggered buffer status report. The instructions are executable by the processor to cause the apparatus determine whether a SR configuration associated with the first logical channel is configured with a set of PUCCH resources for a transmission of a SR on a current active BWP and initiate a RACH procedure for requesting uplink resources if the SR configuration associated with the first logical channel is not configured with the set of PUCCH resources for the transmission of the SR on the current active BWP.
