3. THE DIFFERENT GENERATIONS OF MOBILE
COMMUNICATION

4. WHY? SWITCHING FROM 4G TO 5G

5. DRIVERS FOR 5G
• Main drivers for the evolution of mobile networks in the past were mobile voice(2G/3G/Voice
over Long Term Evolution [VoLTE]), messaging (short messaging service [SMS], WhatsApp) and
Internet access(Wideband Code Division Multiple Access[WCDMA], High Speed Packet
Access[HSPA], Long Term Evolution[LTE],) whenever and wherever needed
5G connectivity will impact the following areas
• Real world mobility: the way we travel and experience our travel
• Virtual mobility: the way we can control remote environment
• High performance infrastructure: the way infrastructure supporter us
• 4th industrial evolution: the way we produce and provide goods

6. ITU-R AND IMT 2020 VISION
• (IMT-R) International Telecommunications Union-Radiocommunications manages the
International radio-spectrum and satellite orbit resources
• In September 2015 ITU-R published its recommendation M.2083 constituting a vision for
the IMT-2020 International Mobile Telecommunications 2020 (ITU’s name for the family of
5G standards)
NOTE: IMT-2000 International Mobile Telecommunications 2000 (ITU’s name for the
family of 3G standards)
• The following trends were identified, leading in a later phase to concrete requirements for
the new 5G system defined by 3rd Generation Partnership Project (3GPP)

10. THE 5G USE CASES
In the context of 5G, one is often talking about three distinctive classes of use cases:
1. enhanced mobile broadband (e-MBB)
2. massive machine-type communication (m-MTC)
3. ultra-reliable and low-latency communication (URLLC)

SPECTRUM BAND OCCUPIED BY 5G

13. MOBILITY WITH MM-WAVES FOR 5G
• Millimetre waves
5G specifications are extending the reach of mobile communication by supporting frequency
bands up to 100 GHz. As we move to high frequencies, the wavelength of the signal moves into
the millimetre
• Available mm-Wave frequency bands
The main advantage of moving to mm-Waves is the uncommitted spectrum that can be used for
5G
The frequency bands under consideration are listed below:

14. TIME-DOMAIN FRAME STRUCTURE FOR 5G

15. TIME DOMAIN STRUCTURE
as shown in the frame structure(previous slide)
• In the time domain, NR transmissions are organized into frames of length 10 ms, each of
which is divided into 10 equally sized subframes of length 1 ms.
• A sub- frame is in turn divided into slots consisting of 14 OFDM symbols each, that is, the
duration of a slot in milliseconds depends on the numerology
• On a higher level, each frame is identified by a system frame number (SFN)
