As in 4G, the multiple access of 5G communications is based on orthogonal frequency division multiple access (OFDMA) for both the downlink and uplink directions. However, contrary to what happens in 4G, the OFDMA design is very flexible, since different use cases with different requirements should be addressed.
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.
Read moreIs 3GPP 5G?
3rd Generation Partnership Project (3GPP) members meet regularly to collaborate and create cellular communications standards. Currently, 3GPP is defining standards for 5G . Different groups, each with a specific focus area, make up 3GPP.
Read moreWhat does G 5G mean?
First, the basics: The “G” stands for generation , meaning 5G is the most current generation of cell phone network coverage and speeds. 3G technology created the first networks fast enough to make smartphones practical.
