16.19.3.1 Mobility in RRC_IDLE and RRC_INACTIVE

The same principles as described in 9.2.1 apply to mobility in RRC_IDLE for ATG and the same principles as described in 9.2.2 apply to mobility in RRC_INACTIVE for ATG unless hereunder specified. The gNB reference location of the serving cell and neighbour cell(s) provided in SIB22 can be used for the UE to perform the idle/inactive measurement and mobility.

The UE can determine whether a network is for ATG connectivity implicitly by the existence of cellBarredATG in SIB1.
