Hi All.

We know RRC connection setup brings config of SRB1.
And RRC connection request goes on SRB0.

So which message is responsible to provide the config of srb0?

SRB0 doesn’t need any specific configuration as it uses CCCH channel.

It is mapped to RLC TM mode, that means no RLC configuration is required.

It is not associated with any PDCP entity.
