The above mentioned requirements are expected to be met by several advancement in technologies such as (i) new waveforms (termed as 5G NR, the new radio), (ii) millimeter wave technology, (iii) massive multiple antenna technologies (iv) non orthogonal multiple access (v) heterogeneous networks such as small cells and …
Read moreWhat is 5G NR air interface?
5G NR is a new air interface being developed for 5G . An air interface is the radio frequency portion of the circuit between the mobile device and the active base station. The active base station can change as the user is on the move, with each changeover known as a handoff.
Read moreWhat are the air interface differences between LTE 4G and LTE Advanced 5G NR?
4G LTE is the fourth generation of mobile networks enabled by the Long Term Evolution technology that offers peak data rates of 300 Mbps; LTE Advanced is an enhancement added to LTE to introduce carrier aggregation, 256 QAM and higher-order MIMO (8×8 & 4×4) for improving peak data rates to 1 Gbps.
Read moreWhich one of the following is a 5G NR model for air interface channel?
The Ericsson AIR 3246 radio was announced in September 2017 and is set to become commercially available in 2018, the first 5G NR for frequency division duplex (FDD). It supports both 4G/LTE and 5G NR technologies.
Read moreWhat are the key air interface technologies that will enable 5G?
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 5G 3GPP standard interface?
The 3GPP 5G RAN architecture – specified in Release 15 and known as NG-RAN – introduces new terminology, interfaces and functional modules. The NG-RAN consists of a set of radio base stations (known as gNBs) connected to the 5G core network (5GC) and to each other .
Read moreWhat is the rat type for 5G?
5G NR (New Radio) is a new radio access technology (RAT) developed by 3GPP for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G networks. The 3GPP specification 38 series provides the technical details behind 5G NR, the RAT beyond LTE.
