Today’s mobile users want faster ...data speeds and more reliable service. The next generation of wireless networks—5G—promises to deliver that, and much more. With 5G, users should be able to download a high-definition film in under a second (a task that could take 10 minutes on 4G LTE). And wireless engineers say these networks will boost the development of other new technologies, too, such as autonomous vehicles, virtual reality, and the Internet of Things.
If all goes well, telecommunications companies hope to debut the first commercial 5G networks in the early 2020s. Right now, though, 5G is still in the planning stages, and companies and industry groups are working together to figure out exactly what it will be. But they all agree on one matter: As the number of mobile users and their demand for data rises, 5G must handle far more traffic at much higher speeds than the base stations that make up today’s cellular networks.

Exclusive: Inside Verizon's 3G and 4G Network | Pocketnow
On the heels of the one-year anniversary of its 4G LTE service [...]
On the heels of the one-year anniversary of its 4G LTE service rollout, Verizon Wireless has granted Pocketnow exclusive access to one of their switches in southeastern Pennsylvania. The switch ...(or Mobile Telephone Switching Office -- MTSO) is a hub of Verizon's network in the Philadelphia tri-state area: it's what connects the towers in the region and processes all voice and data calls. The switch, which is a building filled with miles of fiber optic cable, a battery backup system and a generator system, dozens of servers, and a control room that monitors precise data as it pertains to the performance and stability of the system, is a marvel of engineering and technology.
We also get to witness Verizon's obsession with reliability of their network. Each and every component is redundant within the switch so that if there are any equipment failures or even a natural disaster that disrupts power to the entire facility, Verizon customers are likely to still have service.
We also learn a lot about the difference between Verizon's 3G and 4G network, the latter of which now reaches 200 million people in 190 markets across the U.S., including much of the Philadelphia region. During multiple Q&A session, we learn about the capabilities of Verizon's 4G LTE network, which is only going to increase with further network upgrades.
Thank you to the folks at Verizon Wireless for letting us take a tour of the infrastructure that is responsible for making their network operate. If you want to learn even more about Verizon's network, check out our exclusive tour of their hardware testing lab: http://www.youtube.com/watch?v=7JHXl_rXXRY

Learn about downlink data transmission in 5G New Radio (NR). Explore the Physical Downlink Shared Channel (PDSCH) processing chain which includes LDPC coding, layer mapping, how resource elements are allocated ...for PDSCH transmission, and the different types of PDSCH mapping. A special PDSCH mapping type is used for mini-slots or partially allocated slots, a feature that allows for reduced latency in 5G NR transmission.
We walk you through MIMO precoding, which, although not specified on the downlink, is a critical component of the downlink chain. The example demonstration walks you through PDSCH resource allocation options and mapping in 5G Toolbox and concludes with a quick word on transport block sizes.
Learn about the physical uplink shared channel (PUSCH) and its [...]
Learn about the physical uplink shared channel (PUSCH) and its processing chain, which includes elements already found in the downlink shared channel chain including LDPC coding, modulation schemes, layer mapping, ...and the two types of PUSCH mapping.
The video walks through the significant differences that differentiate the uplink shared channel from the downlink shared channel: the number of layers is limited to 4, there is the possibility of using the optional transform precoding, and MIMO precoding is specified explicitly. The video outlines the two possible types of MIMO precoding: codebook-based precoding and non-codebook-based precoding.

Learn about downlink control information, or DCI, in 5G New Radio. The video walks you through the different types of messages, including downlink assignment and uplink grant, and how they ...are encoded and modulated and then mapped to the 5G New Radio slot via the PDCCH or physical downlink control channel. In the process, you will learn the concepts of resource element groups and control channel elements, the basic units to map control to the OFDM grid.

Explore the concept of control resource sets (CORESETs) and how it applies to downlink control information.
The video looks at the time and frequency structure of a CORESET, and its ...role in downlink control information as the location of the physical downlink control channel (PDCCH). It illustrates the impact of CORESET and PDCCH parameters on the OFDM grid using an interactive example, and it discusses interleaved and non-interleaved mapping. Finally, you will learn how search spaces further reduce the set of blind searches needed for the UE to correctly detect and decode control information.

Learn about physical uplink control channel (PUCCH) and uplink control information (UCI) in 5G New Radio. This video walks through the different types of messages, including HARQ, CQI, and scheduling ...requests. It discusses how they are encoded, modulated, and then mapped to the 5G New Radio slot via the PUCCH or physical uplink control channel. Finally, you’ll learn how control information is used in 5G NR procedures.
Learn about demodulation reference signals or DMRS in 5G New Radio. [...]
Learn about demodulation reference signals or DMRS in 5G New Radio. This video discusses their use in joint precoding and channel estimation. You will also learn about the different settings ...available for DMRS, including time and frequency density and position within a slot.
This includes single-symbol vs. double-symbol, configuration type 1 and 2, mapping type A and B, and additional positions. You will learn how those settings support both single user and MU-MIMO. Finally, this video demonstrates most of those settings with an interactive application written with 5G Toolbox™.
Synchronization Signal Blocks (SSB) in 5G New Radio (NR)
Get an introduction to the synchronization signal block (SSB) in 5G [...]
Get an introduction to the synchronization signal block (SSB) in 5G New Radio (NR). The SSB is comprised of the primary and secondary synchronization signals (PSS and SSS) as well ...as the broadcast channel (BCH), which includes the master information block (MIB).
The PSS enables frame synchronization and, along with the SSS, determination of the physical cell ID. The MIB contains essential pieces of information for a UE trying to get onto the network, such as the location and format of the next piece of information: the system information block type 1 or SIB1. Y
ou’ll learn about the coding and modulation chain for SSB, and what numerologies are applicable. Finally, the video discusses synchronization signal bursts, which are a group of multiple, beamformed SSBs, and their periodicity. The video also shows an example of SSB generation with 5G Toolbox.

This video discusses initial acquisition procedures starting with cell search. By acquiring the primary and secondary synchronization signals (PSS and SSS), you can see the timing and the knowledge of ...the physical cell identity.
The video then discusses physical broadcast channel (PBCH) decoding, how the UE determines the synchronization signal block index with help of the associated demodulation reference signals (DMRS), and the role of the index in initial beamforming acquisition. The master information block, which is carried by the BCH, contains information about the system information block type 1 (SIB1), the next piece of information the UE looks for. The video then illustrates the random access procedure between the UE and the gNodeB, which enables UEs to get onto the network after receiving the SIB1.
