There are three RRC states; RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED are defined for a 5G NR UE. While RRC_IDLE and RRC_CONNECTED states in NR are almost same as those of LTE, the RRC_INACTIVE states is newly introduced in 5G NR.
Read moreWhat is NRDC in 5G?
NR-DC is a Dual Connectivity configuration using the 5GC, whereby both the master and secondary RAN nodes are 5G gNBs .
Read moreWhat is RRC in LTE?
The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station.
Read moreWhat is RRC connected state in LTE?
RRC Connected State LTE UE monitors control channels associated with shared data channel to determine if the data is scheduled for it or not . The Channel quality feedback information is also provided by the UE after measurements. It also performs neighbor cell measurements of UTRAN,EUTRAN and GSM cells.

RRC stands for Radio Resource Control . I personally define RRC as a common language that should be understood by both Network and UE. As you know, UE and Network is communicating via radio channel.
Read moreWhat is the unique identification used to identify the UE context for RRC inactive state?
In case of suspending the RRC connection the RRC Release message contains a set of suspend configuration parameters. The probably most important one is the I-RNTI , the (RRC) Inactive Radio Network Temporary Identity. … Just NGAP RRC Inactivity Transition Report is sent to the AMF.
Read moreWhat is RRC UE?
In summary, a UE is in RRC_CONNECTED when an RRC connection has been established or in RRC_INACTIVE (if the UE is connected to 5GC) when RRC connection is suspended . If this is not the case, i.e. no RRC connection is established, the UE is in RRC_IDLE state.
