CONTENTS

The course describes the physical layer design of NR in terms of OFDM numerologies, radio frames, subframes and slot configurations. The course explains the purpose of, and processing of, all physical channels with particular focus on control channels. Reference signals for data demodulation, CSI measurements, sounding and phase tracking are explained. Layer 1 procedures for synchronization, random access, scheduling and HARQ are described in detail.

An overview of NR layer 2 and layer 3 protocols is included for completeness, with particular focus on the role of the RRC protocol in configuring layer 1 parameters.

PREREQUISITES

Reasonably good technical knowledge of the LTE physical layer and the LTE radio protocols is highly recommended but not compulsory.

Note

This course is not delivered with the FoldOut methodology.
