Mantra:Service Data Adaptation Protocol (SDAP) facilitates implementation of QoS on the New Radio (NR) interface in 5G.Brief Explanation:Like LTE, the NR radio protocol stack utilizes protocols such as Physical (PHY), Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC). NR significantly enhances some of these protocols […]

Mantra: A 5G gNB can be decomposed into two logical components, gNB-CU and gNB-DU.Brief Explanation. In 5G, the next-generation Node B (gNB) and the User Equipment (UE) communicate with each other using the New Radio (NR) air interface protocol stack. The gNB can be decomposed into gNB-Central Unit (gNB-CU) and gNB-Distributed Unit (gNB-DU). The gNB-CU […]

Mantra: 5G NG-RAN consists of gNBs that utilize NR air interface and even ng-eNBs that utilize LTE air interface but connect to the 5GC.Brief Explanation:Formally, the 5G System (5GS) includes the User Equipment (UE), Next-Generation Radio Access Network (NG-RAN), and the 5G Core (5GC) (also known as Next-Generation Core (NGC)). A typical NG-RAN consists of […]

Mantra:ITU has defined three usage scenarios for 5G services: eMBB, URLLC, and mMTC. Please visit https://thewirelessuniversity.com for past Mantras!Brief Explanation: 5G can offer amazing new services (e.g., holograms and factory automation) or enhance traditional services (e.g., video streaming and video calls) on a massive scale. International Telecommunication Union (ITU) has defined usage scenarios such as enhanced Mobile […]

Mantra: 5G aims to support the connection density of a million IoT devices per square kilometer.Visit https://thewirelessuniversity.com for all past Mantras!Brief Explanation:One of the three usage scenarios for 5G is massive Machine Type Communications (mMTC). Many IoT devices such as smart water meters and smart sensors generate very little amounts of data and are delay-tolerant. 5G […]

Mantra: 5G aims for the peak data rate of 20 Gbps.Brief Explanation:According to ITU’s IMT-2020 requirements, 5G needs to support the peak data rate of at least 10 Gbps and even 20 Gbps in some cases. It would be a while before we experience such data rate in practice. Key factors that contribute to such […]
