Back-Off indicator field indicates time delay between PRACH and next PRACH.
Based on the value received in back-off indicator sub header field, UE performs random access procedure.

at times where eNB suffers from lot of traffic,at that instance if a new UE sends a preamble but enb cant give any resources then eNB ask the UE to perform the RACHing after some time.this is informed to the UE in the form of Back off indicator.based on it UE has to wait for next RAChing procedure
