my UE transmits SR to EnodeB but I have SR fail it means the EnodeB not collecting / recognizing / detecting SR requests from the uplint transmission , what attempts should I do /implement in order to solve that problem? it means that the UE isn’t receiving the Up link grant from EnodeB despite that UE transmits SR to ENODEB - fail in getting uplink scheduling grants … the UE is not getting at all the grants back from the EnodeB.

thanks alot for any help on which approaches should I take in order to figure out why this problem is happen … really weird and I dont know what steps should I take to fix the problem.
