Appendix IVMobile front haul and back haulEditor’s Note: Appendix IV was produced during the FG-IMT 2020 focus group in order to investigate gaps in standardization related to IMT-2020. While the request from SG-13 was to deliver a report outlining standardization gaps, the consensus of the focus group was that the working documents produced and used during the focus group work contained useful information for future work and should be captured. Note, however, the focus group concentrated on producing accurate descriptions of the standardization gaps in the main body of this document; some minor errors may exist in the appendices. They are, however, the output of the focus group but are provided for information only. Editor’s Note: This appendix uses clause references in a form usually associated for normative text. This is maintained for this report to align with references made in the main body of this report. The original text was assuming and Appendix D, not the current Appendix IV This document contains the baseline of Annex D going into the Beijing meeting. Comments discussed on the Oct. 14 teleconference have been addressed. Annex D: Mobile front haul and back haul – Drivers, Challenges, and Solutions
This document contains material relevant to Mobile Front-haul and Mobile Back-haul.
