This document is related to the technical report for physical layer aspect of the study item "Study on New Radio Access Technology" [2]. The purpose of this TR is to help TSG RAN WG1 to define and describe the potential physical layer evolution under consideration and compare the benefits of each evolution techniques, along with the complexity evaluation of each technique. This activity involves the Radio Access work area of the 3GPP studies and has impacts both on the Mobile Equipment and Access Network of the 3GPP systems. This document is intended to gather all information in order to compare the solutions and gains vs. complexity, and draw a conclusion on way forward. This document will be kept up-to-date via CRs in the future.
