Qualcomm and ZTE Make 5G Voice Over NR Call
Qualcomm and ZTE have established 5G-enabled Voice over New Radio call. The call was performed in compliance with 3GPP Release 15 specifications over the 2.5 GHz spectrum band (n41) by utilizing a ZTE’s 5G NR base station and a 5G smartphone form factor test device powered by a Qualcomm® Snapdragon™ 5G Modem-RF System.
3GPP Approves List of Release 17 5G New Radio Features and Functions
Earlier this week 3GPP held RAN#86 to discuss and finalize further technology evolution of 5G NR radio. 3GPP has now approved a list of features and detailed functionality that will be part of Release-17.
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;
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.
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.
5GNR Reference Signals Measurement
In 5G new radio (NR) system, reference signal measurement are used to perform cell selection, cell reselection and handover etc. Reference Signal (RS) measurements are further classified into three measurement parameters as given
Ericsson and Qualcomm Complete Interoperability Testing of 5G NR Data Call on 2.6 GHz Band
Ericsson and Qualcomm have completed a non-standalone (NSA) 5G New Radio (NR) data call on 2.6 GHz, adding a new frequency band to those successfully tested for commercial deployment. The bi-directional downlink and uplink data call was made at the Ericsson Lab in Kista, Sweden last December 20.
