how many times rrc connection retransmit if setup get fail
maximum number of re-transmissions is 8.
can you please explain why-8
The maximum number of MSG3 re-transmissions for new connections can be controlled using harqMaxMsg3 from 1…8,step 1 configured for each UE at initial access to a specific cell (see 3GPP TS 36.321)
increasing to Max will improve accessibility due to the additional reliability provided by the extra re-transmissions but The average call setup time may increase due to the connections which previously failed but now establish with an increased number of re-transmissions.
