CCE (Control Channel Element) One CCE is made of multiple REGs. Aggregation level It indicates number of allocated CCEs for PDCCH. It can be 1/2/4/8/16. Time domain and frequency domain parameters of CORESET are defined in TS 38.211 document. RRC signaling message consists of following fi...
I-RNTI It is used to identify the UE context in RRC_INACTIVE. 5G NR Network IdentifiersFollowing table-6 defines different types of 5G NR Network identifiers. Network IdentitiesDescription AMF Name It is used to identify an AMF. NCGI (NR Cell Global Identifier) It is used to identify NR...
Key RRC parameters relevant to RedCap device For the 5G gNB, the primary impact from the introduction of RedCap devices is the need to adapt to their specific features during the initialCell campingandRACH processand when the device stays connected. New information elements (IEs) handle those ...
With the data flowing from a UE via a source gNB to the data plane of the 5G Core (User Plane Function / UPF), Radio Resource Control (RRC) signaling is employed to continuously measure and report on signal quality. When the source node detects that a handover...
In 4G (LTE), we use Common Public Radio Interface (CPRI) interface as fronthaul connection, but now, enhanced CPRI (i.e. eCPRI) is becoming an important technology for 5G and Open RAN. The scope of the eCPRI specification is to enable efficient and flexible radio data transmission via a...
With the data flowing from a UE via a source gNB to the data plane of the 5G Core (User Plane Function / UPF), Radio Resource Control (RRC) signaling is employed to continuously measure and report on signal quality. When the source node detects that a handover is required, it...
In the 5G context, the O-RAN Alliance has selected split 7.2x, which lies between the lower part of the physical layer (Low-PHY) and the upper part of the physical layer (High-PHY). The open fronthaul interface between O-DU and O-RU is defined at the 7.2x split. ...

The primary component carrier is numbered zero, for all instances, and the different secondary component carriers are assigned a unique number through the UE specific RRC signalling. This means that even if the terminal or user equipment and the base station, eNodeB may have different...
in the RRC_CONNECTED state to contact the ProSe function. The ProSe authorization is always done on per PLMN basis. However, the UE is not required to registered in the PLMN where it wants to do ProSe communication. In this case, the UE needs to contact the ProSe Function in its HPLMN....
