To enable devices to find a cell when entering a system, as well as to find new cells when moving within the system, a synchronization signal consisting of two parts, the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS), is periodically transmitted on the downlink from each NR cell.
The PSS/SSS, together with the Physical Broadcast Channel (PBCH), is jointly referred to as a Synchronization Signal Block or SS block
The PSS is transmitted in the first OFDM symbol of the SS block and occupies 127 subcarriers in the frequency domain. The remaining subcarriers are empty.
• The SSS is transmitted in the third OFDM symbol of the SS block and occupies the same set of subcarriers as the PSS. There are eight and nine empty subcarriers on each side of the SSS.

The CORESET configuration obtained from the PBCH also defines and activates the initial bandwidth part in the downlink.
The initial active uplink bandwidth part is obtained from the system information scheduled using the downlink PDCCH.
Once connected, a device can be configured with up to four downlink bandwidth parts and up to four uplink bandwidth parts for each serving cell.
On each serving cell, at a given time instant one of the configured downlink bandwidth parts is referred to as the active downlink bandwidth part for the serving cell and one of the configured uplink bandwidth parts is referred to as the active uplink bandwidth part for the serving cell.

There have been two views of what 5G should be:
Hyper connected view
and Next generation radio-access technology
5G is used across three main types of connected services, including enhanced mobile broadband, mission-critical communications, and the massive machine communications.
A defining capability of 5G is that it is designed for forward compatibility the ability to flexibly support future services that are unknown today.
» Read moreThere are several reasons that 5G will be better than 4G:
5G is significantly faster than 4G.
delivering up to 20 Gigabits-per-second peak data rates and more than 100 Megabits-per-second average data rates. 5G has more capacity than 4G.
5G is designed to support a multiple of 100 increase in traffic capacity and network efficiency.

It is a new global wireless standard after first G, 2G, 3G, and 4G networks.
5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.
