scope:

The present document contains the outcome of a series of initial technical studies focused on the MAC and higher layers of DECT-2020: New Radio Interface (NR). DECT-2020 NR is a state of the art radio interface based on OFDM and supporting MIMO and is able to offer the required data rates, spectrum efficiency and other characteristics to become an IMT-2020 radio interface as defined by ITU-R.

The PHY layer study of DECT-2020 is described in ETSI TR 103 514 [i.26].

The present document does not attempt to close the topic and subsequently, more detailed studies, on the different layers are expected in further project stages.

The material described in the present document contains the outcome of STF 564, an ETSI task force created to perform the initial studies on the field, along with other contributions from the DECT industry.

For the purpose of the present document the terms "DECT-2020", "DECT-2020 New Radio" or "DECT-2020 NR" all have the same meaning, and all of them refer to DECT utilizing the new radio interface based on OFDM as described in ETSI TR 103 514 [i.26] (PHY layer) and in the present document (MAC and higher layers). 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.

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 efficiency and large numbers of client nodes.
