1. A method for wireless communication performed by an apparatus of a user equipment (UE), comprising:
determining a first amount of data in a UE data buffer;
triggering a scheduling request (SR) for a communication link in response to determining the first amount of data in the UE data buffer;
prior to outputting the SR for transmission to a base station (B S) via the communication link, determining whether a second amount of data in the UE data buffer is less than a threshold,
determining that the communication link does not have scheduled data retransmissions, control messages, or status feedback messages; and
cancelling the SR at the UE prior to outputting the SR for transmission to the BS in response to:
determining that the second amount of data in the UE data buffer is less than the threshold, and
determining that the communication link does not have scheduled data retransmissions, control messages, or status feedback messages.
