TECHNOLOGY FOCUS

The standardization of 5G New Radio (NR) was complete in 2018 and standard compliant deployments are expected early 2020. NR will provide new services like Enhanced Mobile Broadband, Massive Machine Type Communications and Ultra-Reliable and Low Latency Communications.

New extreme requirements include peak data rates of up to 20 Gbps in downlink / 10 Gbps in uplink and latencies as low as 0.125 ms.

Based on the explanation of the shortcomings of LTE, the physical layer principles of 5G will be introduced. Among others, this includes discussion about the waveform, access scheme, duplex mode, frame structure, coding and modulation. Advanced MIMO schemes, with the use of extensive beam forming, are one essential component for 5G and are explained in detail. This will also result in different design of the various signals, channels and procedures in up- and downlink.

The training will introduce how to cell search, synchronization and broadcast signalling is done as well as random access. Based on its attendance in 3GPP, the trainer will also provide the latest update of 5G standardisation in 3GPP.

COURSE CONTENT

This training will first discuss 5G requirements, deployment scenarios and spectrum assumptions. Based on the explanation of the shortcomings of LTE, the physical layer principles of 5G will be introduced. Among others, this includes discussion about the waveform, access scheme, duplex mode, frame structure, coding and modulation.

Advanced MIMO schemes, with the use of extensive beam forming, are one essential component for 5G and are explained in detail. This will also result in different design of the various signals and procedures in up- and downlink.

The training will introduce how to cell search, synchronization and broadcast signalling is done as well as random access. Resource assignments are done quite differently to ensure ultra-low latency as well as forward compatibility with future phases of 5G.

Based on its attendance in 3GPP, the trainer will also provide the latest update of 5G standardisation in 3GPP.

Combine this course with course No 042 "5G Radio Protocol and Architecture" for the best learning effect. Please note that participants attending both course No 041 and course No 042 will benefit from a reduced total course fee. Book the Bundle course.

WHO SHOULD ATTEND

The course is suitable for engineers that already work 2G/3G or 4G systems and are interested in future evolution towards 5G.

The course is held by a technical expert in the field that is directly involved in 3GPP standardization and provides a hands on up to date background information of the latest trends in this industry. Therefore, it is suitable for all kind of engineers from research, development, planning, deployment, regulation and operation as well as executives, managers and system architects.

Pre-existing knowledge of LTE technology is required for a full understanding of the technical details of 5G NR.
