Claim 14:
15. A method for wireless communication performed by an apparatus of a user equipment (UE) that supports a split data radio bearer (DRB), comprising:
determining that a first amount of data in a UE data buffer is greater than a first threshold;
triggering a first scheduling request (SR) for a first communication link and a second SR for a second communication link in response to determining that the first amount of data in the UE data buffer is greater than the first threshold, wherein the first communication link is a secondary communication link and the second communication link is a primary communication link,
outputting the first SR for transmission to a first base station (BS) via the first communication link;
prior to outputting the second SR for transmission via the second communication link, determining whether a second amount of data in the UE data buffer is less than a second threshold;
determining, after the second SR is triggered for the primary communication link, that the second amount of data in the UE data buffer is less than the second threshold; and
cancelling the second SR at the UE prior to transmission of the second SR to a second BS via the primary communication link in response to determining that the second amount of data in the UE data buffer is less than the second threshold.
