there is something 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.

Thanks. But what if BSR Retranmission keeps happening and eNB didnt give grant?Is there any recovery for this?
Hi Himani thanks for this question. frankly i even didn't about this, read through some documents.
RRC configures MAC with Periodic-BSR timer and retxBSR timer values (Mac-main-config IE).So even after eNB doesn't responds to any BSR, UE will initiate RA or SR.
