"The present document aims on studying ""DECT-2020: New Radio""@ a new radio interface based on state of the art paradigms able to offer the required data rates@ propagation characteristics and spectrum efficiency@ while maintaining compatibility with the carrier and time structure of the DECT band. The present document is focused on the Physical layer. DECT-2020@ as defined by the present document@ will be based on OFDM and may support space multiplexing (MIMO). The study focuses on: 1) Review of use cases and key application areas for DECT-2020. 2) Identification of methodology@ initial sources@ simulation tools and models. 3) Initial definition of ""DECT-2020: New Radio"" PHY layer@ providing guidance for a following technical specification. 4) Preliminary simulation results and preliminary study on spatial multiplexing (MIMO)."
