5G NG Interface Protocol Architecture
The NG user plane interface (NG-U) is defined between the NG-RAN node and the UPF. The transport network layer is built on IP transport and GTP-U is used on top of UDP/IP to carry the user plane PDUs between the NG-RAN node and the UPF. NG-U provides non-guaranteed delivery of user plane PDUs between the… Continue reading 5G NG Interface Protocol Architecture
Separation of gNB-CU-CP and gNB-CU-UP
gNB-CU-Control Plane (gNB-CU-CP): a logical node hosting the RRC and the control plane part of the PDCP protocol of the gNB-CU for an en-gNB or a gNB. The gNB-CU-CP terminates the E1 interface connected with the gNB-CU-UP and the F1-C interface connected with the gNB-DU.
5G NG-RAN Radio Protocol Architecture
The different sublayers used in Radio Protocol Architecture are: Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP) and Service Data Adaptation Protocol (SDAP), Radio Resource Control (RRC) and Non-Access Stratum (NAS). Where: -The physical layer offers to the MAC sublayer transport channels;
5G NG-RAN Architecture
gNB Central Unit (gNB-CU): a logical node hosting RRC, SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that controls the operation of one or more gNB-DUs. The gNB-CU terminates the F1 interface connected with the gNB-DU.
Functional Split between NG-RAN and 5GC
The gNB and ng-eNB host the following functions: -Functions for Radio Resource Management: Radio Bearer Control, Radio Admission Control, Connection Mobility Control, Dynamic allocation of resources to UEs in both uplink and downlink (scheduling);
Ericsson and Intel to Demonstrate 4G + 5G Dynamic Spectrum Sharing at MWC 2019
Ericsson will showcase activation of Ericsson Spectrum Sharing with an Intel 5G device at Mobile World Congress 2019. The demo will show that 4G and 5G traffic can run simultaneously on the same frequency carrier.
5G Tool box in MATLAB: Possibilities and Limitations
MATLAB has introduced its 5G Toolbox, which provides standards compliant waveforms and reference examples for modeling, simulation, and verification of the physical layer of 3GPP 5G New Radio (NR) communications systems. 5G Toolbox can be used to design algorithms and predict end-to-end link performance of systems that conform to the 5G Release 15 standard.
5G Tests, Trials Gain Momentum Across Globe
5G has gathered momentum globally as per latest GSA report. 201 operators, in 83 countries are currently investing in 5G mobile and 5G FWA networks, ~30% increase since mid-2018. Level of commitments include tests, trials, planned and pilot deployments, and launches.
Small Cell In 5G
As the need and dependency on wireless network is increasing, a stronger and faster network is required to cater to the demands of millions. The 5G networks are the next generation of mobile internet connectivity, offering faster speeds and more reliable connections on smartphones and other devices than ever before.
