Various aspects of the present disclosure relate to a UE that receives a group RRC release message that is based on a group mobility configuration, the group RRC release message intended for communication to a group of multiple UEs. The UE can switch to a RRC inactive state based in part on a determination that a RRC connection suspend configuration directed to the UE is included in the group RRC release message. The UE can switch to a RRC idle state based in part on a determination that the RRC connection suspend configuration is not included in the group RRC release message. A network entity can generate the group RRC release message with the group mobility configuration, and the group RRC release message is intended for communication to the group of multiple UEs. The network entity can then transmit the group RRC release message to the group of multiple UEs.
