Hi Akhilesh,

There is a RRC IE called BSR Prohibit timer . Once UE sends BSR then it starts the BSR timer, until it expires it will not resend the BSR. After expiry UE will send the BSR again.

What is padding BSR and why it is needed? How ever normal BSR also can carry same information but why do we need specific padding BSR?

Hi All,

I have a question related to BSR reporting, BSR trigger is very complicated

Suppose MAC has data of 20 bytes, but Grant received from network is 30 bytes, so will MAC send 20 bytes data + Padding BSR. or 10 bytes padding data,Because as far as i know, if Grant is enough to accommodate BSR as well, MAC will send BSR as well.

Please clarify this doubt.

Thanks

If UE gets more than enough grant to send BSR and enough to send the data , then will UE sends BSR in the SR grant or not ?
