what does mean by periodicity of sibs and mibs ?

Question

Can someone please explain about the cause "loadBalancingTAUrequired" ?

Answer 1

si_Periodicity tells about the period in terms of radio frames which helps the UE to read the required SIB. The value of this parameter is used for calculating the Radio frame where SI will be received.

You will get good idea of System information mapping.

Please correct me ,If I am wrong.

Answer 2

Periodicity means occurance and following is the schedule -
a) MIB is transmitted at the fixed cycles (every 4 frames starting from SFN 0)
b) SIB1 is transmitted at the fixed cycles (every 8 frames starting from SFN 0).
c) All other SIBs are being transmitted at the cycles specified by SIB scheduling information elements in SIB1

Let me know if you are looking something different.
