1. A method comprising:
receiving, by a user equipment (UE), a first UE identifier (ID) for use when the UE is in a Radio Resource Control (RRC)_Connected active state;
receiving, by the UE, a second UE ID for use when the UE is in a RRC_Inactive state, wherein a bit length of the first UE ID is shorter than a bit length of the second UE ID and the first UE ID and the second UE ID are each a different radio network temporary identifier (RNTI) that are independent of one another, and the RRC-Inactive state is different from the RRC_Connected active state and a RRC_Idle state;
transitioning, by the UE, from the RRC_Connected active state to the RRC_Inactive state;
performing, when the UE is in the RRC_Inactive state, grant free communications using the second UE ID, or using the second UE ID for uplink based measurements;
transitioning, by the UE, from the RRC_Inactive state to the RRC_Connected active state; and
maintaining, by UE, the second ID after transitioning from the RRC_Inactive state to the RRC_Connected active state.
