A: 5G is based on OFDM (Orthogonal frequency-division multiplexing) , a method of modulating a digital signal across several different channels to reduce interference. 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.
Read moreWhat is MAC PDU in LTE?
LTE MAC PDU is a bit string but octet aligned (i.e multiple of 8 bits) . A MAC PDU header consists of one or more subheaders. Each subheader corresponds to either a MAC SDU, MAC control element or padding. MAC PDU header can have these six elements R/R/E/LCID/F/L.
Read moreWhat is LTE protocol stack?
The protocol stack functions consist of the Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC) . LTE is the latest generation of the 3GPP standards. The LTE standard specifies an IP-only network supporting data rates up to 150 Mbps.
Read moreWhat is RRC and PDCP?
PDCP stands for Packet Data Convergence Protocol . It is a layer of 5G NR radio protocol stack. It is placed top of the RLC Layer and below of the SDAP layer(for user plane) or RRC layer (for control plane) in the Radio Protocol Stack in 5G NR. Due to header compression functionality, it is called as convergence …
Read moreWhat is 5G architecture?
5G Core Architecture The new 5G core, as defined by 3GPP, utilizes cloud-aligned, service-based architecture (SBA) that spans across all 5G functions and interactions including authentication, security, session management and aggregation of traffic from end devices .
Read moreWhat is 5G protocol stack?
5G protocol or NR protocol stack is very much similar to the LTE (4G) protocol stack . Similar to 4G (LTE), depending upon the direction of data to be processed, 5G radio protocol stack has two categories: Control Plane (C-Plane) Stack. User Plane Stack.
