This document is related to the technical report for this study item "Scenarios and Requirements for Next Generation Access Technologies" [1]. The objective of the study item is to identify the typical deployment scenarios associated with attributes such as carrier frequency, inter-site distance, user density, maximum mobility speed, etc, and to develop requirements for next generation access technologies for the identified deployment scenarios taking into account, but not limited to, the ITU-R discussion on IMT-2020 requirements.
This document contains scenarios and requirements for next generation access technologies, which can be used as not only guidance to the technical work to be performed in 3GPP RAN WGs, but also input for ITU-R to take into account when developing IMT-2020 technical performance requirements.

4 Introduction p. 8
At the 3GPP TSG RAN #70 meeting, the Study Item description on "Scenarios and Requirements for Next Generation Access Technologies" was approved [1].
The justification of the Study Item was that a fully mobile and connected society is expected in the near future, which will be characterized by a tremendous amount of growth in connectivity, traffic volume and a much broader range of usage scenarios. Some typical trends include explosive growth of data traffic, great increase of connected devices and continuous emergence of new services. Besides the market requirements, the mobile communication society itself also requires a sustainable development of the eco-system, which produces the needs to further improve system efficiencies, such as spectrum efficiency, energy efficiency, operational efficiency and cost efficiency. To meet the above ever-increasing requirements from market and mobile communication society, next generation access technologies are expected to emerge in the near future. A study item to identify typical deployment scenarios for next generation access technologies and the required capabilities in each corresponding deployment scenarios should be considered.
5 Objectives p. 8
In order to meet the deployment scenarios and requirements, studies for next generation access technologies should be carried out in at least, but not limited to, the following areas, designs for next generation access technologies RAN should strive for enough flexibility to support current envisaged and future requirements for the different use cases, e.g., from SA1 TR 22.891, i.e., to support for wide range of services.
