In 5G, One NR Resource Block (RB) contains 12 sub-carriers in frequency domain similar to LTE . In LTE resource block bandwidth is fixed to 180 KHz but in NR it is not fixed and depend on sub-carrier spacing.24 Nis 2019
Read moreWhat is RRC IE?
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.
Read moreWhat is RRC state?
Radio Resource Control ( RRC ) is a layer within the 5G NR protocol stack . It exists only in the control plane, in the UE and in the gNB . The behaviour and functions of RRC are governed by the current state of RRC . In 5G NR , RRC has three distinct states: RRC_IDLE, RRC_CONNECTED and RRC_INACTIVE.6 Mar 2021
Read moreWhat are the difference between RRC IDLE and RRC connected states in LTE?
Differences between LTE RRC states and UMTS RRC States In LTE there is only 2 RRC states i.e. RRC_IDLE and RRC_CONNECTED whereas in UMTS system RRC has a 5 state i.e. IDLE, CELL_FACH, CELL_DCH, CELL_PCH and URA_PCH.
Read moreWhat happens when UE is switched on in 5G?
The UE is notified about the 5G bearer via the RRC Connection Reconfiguration message. The UE then connects to the 5G network while maintaining the connectivity to the 4G network .
