[srslte-users] srsUE attaches successfully but then disconnects

[Samie Mostafavi]

Thank you Ismael and Andre for your comments,
@Ismael why do you think it is related to the srsLTE version? I am gonna
give it a try...

@Andre
Loosing the sync is solved but it is still not working. In the log I have
many instances of this message:
[MAC ] [W] [06918] DL PID 5: Received duplicate TB0. Discarting and
retransmitting ACK (n_retx=3, reset=no)

and on the enb side, it shows:
[MAC]   [eNB 0][PUSCH 0] CC_id 0 684.8 ULSCH in error in round 0, ul_cqi
221, UE_id 0, RNTI ce19 [MAC]
[MAC]   [eNB 0][PUSCH 0] CC_id 0 685.6 ULSCH in error in round 1, ul_cqi
223, UE_id 0, RNTI ce19 [MAC]
[MAC]   [eNB 0][PUSCH 0] CC_id 0 686.4 ULSCH in error in round 2, ul_cqi
225, UE_id 0, RNTI ce19 [MAC]
[MAC]   [eNB 0][PUSCH 0] CC_id 0 687.2 ULSCH in error in round 3, ul_cqi
229, UE_id 0, RNTI ce19 [MAC]
[MAC]   [eNB 0][PUSCH 0] CC_id 0 688.0 ULSCH in error in round 0, ul_cqi
225, UE_id 0, RNTI ce19 [MAC]

Any idea about this?
Best,
Samie
