Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Digital Enhanced Cordless Telecommunications (DECT). The present document presents a
25、study of a new radio interface named DECT-2020. DECT-2020 is a state of the art radio interface based on OFDM with options for MIMO and is intended as long-term evolution of DECT technology. The present document is focused on the Physical layer. Modal verbs terminology In the present document “shoul
26、d“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Int
27、roduction The current DECT radio interface was designed in the early 1990s and is based on TDMA/TDD with Gaussian Frequency Shift Keying (GFSK) modulation. Although this interface is able to provide a cost-effective solution for cordless telephony applications with an appropriate reuse of the spectr
28、um, it cannot provide the high data rates and bandwidth efficiency required by most modern evolution scenarios. In addition, promising applications such as Audio-Streaming and Wireless Industrial Automation in Internet of Things (IoT) domain introduces Ultra Reliability and Low Latency requirements
29、that have to be taken into account in any technology evolution. IMT-2000 is the term used by the International Telecommunications Union (ITU) for a set of globally harmonised standards for third generation (3G) mobile telecoms services and equipment. 3G services are designed to offer broadband cellu
30、lar access at speeds of 2Mbps, which will allow mobile multimedia services to become possible. DECT is, and will continue to be, one of the IMT-2000 technologies. However, the ITU work continued, first with IMT-Advanced, and it is now going further with IMT-2020. The term IMT-2020 was coined in 2012
31、 by the ITU and means International Mobile Telecommunication system with a target date set for 2020, with the intention of addressing fifth generation (5G) mobile telecoms services and equipment. ETSI ETSI TR 103 514 V1.1.1 (2018-07) 6The ETSI DECT Technical Committee and the industry body DECT Foru
32、m are currently supporting activities to develop DECT to meet the IMT-2020 requirements. This will require major changes to the existing DECT standards, and specifically to the MAC and PHL layers. For the purpose of the present document the terms “DECT-2020“, “DECT-2020 New Radio“, “DECT-2020 NR“ or
33、 “PHL-2020“ have all the same meaning and all of them refer to the new radio interface based on OFDM outlined in the present document. This new radio interface is targeted to meet the IMT-2020 requirements. The terms FP-2020 or PP-2020 refer to FP and PP (respectively) devices supporting DECT-2020.
34、The present document is motivated by recent efforts to identify new ways of utilizing efficiently DECT frequency bands and potentially additional bands. New modes of operation are defined to target a more diverse set of use cases, while addressing 5G requirements for low latency, high spectral effic
35、iency and large numbers of client nodes. ETSI ETSI TR 103 514 V1.1.1 (2018-07) 71 Scope 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,
36、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 an
37、d 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 spa
38、tial multiplexing (MIMO). 2 References 2.1 Normative references Normative references are not applicable in the present document. 2.2 Informative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
