Buffer status reporting for extended reality service

A method, comprising:

• receiving an indication of whether a first buffer status report (“BSR”) format is usable;
• in response to the indication indicating that the first BSR format is usable, determining a buffer size based on a first table that comprises buffer size levels corresponding to a first buffer size field;
• in response to the indication indicating that the first BSR format is not usable, determining the buffer size based on a second table that comprises buffer size levels corresponding to a second buffer size field, the first buffer size field being shorter than the second buffer size field;
• and
• transmitting a BSR based on the buffer size.

A network equipment (NE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and;
• configured to cause the NE to:
• transmit an indication of a buffer status report (“BSR”) format to be used for a BSR;
• and
• receive a BSR according to the BSR format, wherein:
• in response to the indication indicating that a first BSR format is usable, determine a buffer size based on a first table that comprises buffer size levels corresponding to a first buffer size field;
• and
• in response to the indication indicating that the first BSR format is not usable, determine the buffer size based on a second table that comprises buffer size levels corresponding to a second buffer size field, the first buffer size field being shorter than the second buffer size field.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• receive an indication of whether a first buffer status report (“BSR”) format is usable;
• in response to the indication indicating that the first BSR format is usable, determine a buffer size based on a first table that comprises buffer size levels corresponding to a first buffer size field;
• in response to the indication indicating that the first BSR format is not usable, determine the buffer size based on a second table that comprises buffer size levels corresponding to a second buffer size field, the first buffer size field being shorter than the second buffer size field;
• and
• transmit a BSR based on the buffer size.
