Classification: CPC H | IPC H

Claim 4:
5. 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 primary communication link and the second communication link is a secondary communication link;
outputting the first SR for transmission to a first base station (BS) via the first communication link; and
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 secondary 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 outputting the second SR for transmission to a second BS via the secondary communication link in response to the second amount of data in the UE data buffer being less than the second threshold.
