What is NSA mode?

What is NSA mode?

NSA is a 5G radio access network (RAN) that operates on a legacy 4G LTE core -- known as Evolved Packet Core (EPC) -- and manages control plane functions. NSA includes both a 4G and 5G base station, but the 4G base station takes precedence.

How do I download 3GPP specs?

The 3GPP specs are published as ETSI deliverables, and these are available in PDF form http://www.etsi.org/standards-search. But you can download a free Word viewer (i.e. read only) from the Microsoft web site.

What is Android 3GPP commands?

AT commands are software interface for wireless modules. AT commands are defined as part of 3GPP standard under 3GPP TS 27.007. That implies that all the wireless modules that operate on cellular networks are required to support AT commands.

Which 5G technologies are defined in 3GPP 15?

3GPP Rel. 15 and Industry Improvements. With 3GPP, significant technology improvements, including an entirely new air interface — 5G New Radio (NR) — will follow advances in LTE, LTE-Advanced and LTE-A Pro. Technology will need to adapt to improvements in speed.

Does 5G use OFDM?

The 5G New Radio (NR) standard uses OFDM on both the uplink and downlink. The NR specification is designed with a high degree of flexibility to cover a diverse set of applications.

What is TCP in 5G?

Abstract: In today's data networks, the main protocol used to ensure reliable communications is the transmission control protocol (TCP). The TCP performance is largely determined by the used congestion control (CC) algorithm.

Is 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.

What is split bearer in 5G?

Me: Split bearer is a function to allow the split of data going to gNB from the core side into two paths, the 1st path through the 5G air interface toward the UE and the 2nd one is toward X2 interface with the anchored eNB and then eNB will transfer this data through the 4G air interface to the UE.

How does 5g beamforming work?

Beamforming OverviewBeamforming is used with phased array antennae systems to focus the wireless signal in a chosen direction, normally towards a specific receiving device. This results in an improved signal at the user equipment (UE), and also less interference between the signals of individual UE.

Is LTE full-duplex?

LTE is able to utilise both frequency division and time division, FDD & TDD (TD-LTE) forms of duplex to accommodate the uplink and downlink. LTE can utilise both FDD - frequency division duplex and TDD - time division duplex, often referred to as TD-LTE.
