TECHNOLOGY FOCUS

5G is the next generation radio access technology that is currently in the phase of development and standardization. End of this year first trial will start and commercial deployment of fully standard compliant equipment is expected early 2020. 5G will provide new services like Enhanced Mobile Broadband (eMBB), Massive Machine Type (mMTC) Communications and Ultra-Reliable and Low Latency Communications (URLLC). New extreme requirements include peak data rates of up to 20 Gbps in downlink / 10 Gbps in uplink and latencies as low as 1 ms. 5G shall also enable communication using massive MIMO techniques leveraging beam forming in very high frequency bands > 6GHz (cm-wave, mm-wave). Based on its attendance in 3GPP, the trainer will also provide the latest update of 5G standardisation in 3GPP.  

COURSE CONTENTS

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.
