Techniques for buffer status report and scheduling request in new radio

A method for wireless communications at a user equipment (UE), wherein the UE supports multiple configured numerologies, multiple configured TTIs, or both, the method comprising:

• determining that spare resources are available in one or more of the multiple configured numerologies, multiple configured TTIs, or both, wherein the spare resources are uplink resources sufficient to include a padding BSR;
• selecting one of the one or more multiple configured numerologies, multiple configured TTIs or both for transmitting a padding BSR to a base station;
• generating a BSR;
• and
• transmitting the BSR to the base station, wherein the transmitting of the BSR includes transmitting a padding BSR over the selected one of the one or more of the multiple configured numerologies or the multiple configured TTIs, or both.

An apparatus at a user equipment (UE) for wireless communications, comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory and configured to execute the instructions to:
• receive new data;
• receive, from a base station, a UL grant smaller than a first configured threshold;
• generate a buffer status report (BSR) for new radio wireless applications;
• and
• transmit the BSR to a base station, wherein to generate the BSR and transmit the BSR occur in response to receiving the new data and the UL grant and having an unserved portion of a last reported data in a corresponding logical channel drop below a second configured threshold, the BSR including information reporting a size of the new data.
