FAQ's

What is X2-EUTRAN handover and how is it performed?

X2-E-UTRAN Handover is used to hand over a UE from a source eNodeB to a target eNodeB using X2 when the MME and SGW are unchanged. The presence of IP connectivity between the Serving GW and the source eNodeB, as well as between the Serving GW and the target eNodeB is prerequisite and this is where ANR functionality can help.

When a Radio Link Failure (RLF) is detected in LTE?

Radio link failure to be detected upon T310 expiry in the physical layer as part of a procedure called Radio Connection Supervision (RCS), upon random access problem indication from MAC while neither T300, T301, T304 nor T311 is running and finally upon indication from RLC that the maximum number of re-transmissions has been reached

What is Back-off Indicator and how it is used?

Backoff Indicator is a special MAC subheader in MAC CE that carries the parameter indicating the time delay between a PRACH and the next PRACH. If the Random Access Response contains a Backoff Indicator subheader then UE sets the backoff parameter value as indicated by the BI field of the Backoff Indicator subheader and restarts the PRACH preamble transmission procedure.
