4 Technologies evaluated by the ETSI Evaluation
Group
The ETSI EG focus on evaluating the DECT-2020 NR component RIT of the SRIT proposed by ETSI TC DECT and
DECT Forum in the submission in Contribution IMT-2020/17 (Rev. 1) [i.15].
The ETSI EG and its members have utilized the ITU-R evaluation guidelines in Report ITU-R M.2412-0 [i.3].
The following additional evaluation methodologies to complement the evaluation guidelines have been used:
a) Connection density evaluation of Mesh networking technology requires:
- to select a D2D channel model;
- to define a cost function for the next-hop selection;
- to handle simulation complexity, it is noted that it is hard to drive the technology to an outage rate of 1 %
just by increasing device numbers.
b) The following recommendations by ETSI TC DECT are considered:
- D2D channel models of 3GPP are adopted: 3GPP TR 36.843 [i.10] (p. 39), ETSI TR 138 901 [i.11],
Report ITU-R M.2135-1 [i.4], Table 8-7 (p. 17).
- Cost function is solely the number of hops required to reach RD, FT (BS).
- The evaluation procedure in section 7.1.3 in Report ITU-R M.2412-0 [i.3] aims at finding N' (devices per
TRxP) satisfying a packet outage rate of 1 %. The essence of the criteria is evaluated which is the
connection density of 1 000 000 devices/km with a maximum 1 % outage rate. This ensures that
simulation complexity can be handled.
c) Further, increasing traffic rates as encouraged by Report ITU-R M.2412-0 [i.3] is investigated.

5.2.4.2.1 Frequency bands identified for IMT
Is the proposal able to utilize at least one frequency band identified for IMT in the ITU Radio
Regulations [i.13]?  YES /  NO
Specify in which band(s) the candidate RIT or candidate SRIT can be deployed.
According to information provided in Contribution 5D/1299 [i.14] (characteristic template under
clauses 5.2.3.2.8.3 and 5.2.4.1.1 of self-evaluation), the DECT-2020 NR component aims to operate
in:
• 1 880 MHz to 1 900 MHz
• 1 900 MHz to 1 980 MHz and 2 010 MHz to 2 025 MHz (IMT-2000 FT bands)
• Any other frequency band including above 24,25 GHz
Further frequencies at the 5 GHz band have been considered as possible.
According to published ETSI technical specifications, the following bands are supported by
release 1 of DECT-2020 NR:
Band number Receiving band (MHz) Transmitting band (MHz)
1 1 880 to 1 900 1 880 to 1 900

16 4 800 to 4 990 4 800 to 4 990
17 5 725 to 5 875 5 725 to 5 875

Some of these bands have been identified for IMT (see Recommendation ITU-R  M.1036-6 [i.5]).
The proposed SRIT can support additional IMT frequency ranges due to the component RIT 3GPP
5G NR.
In conclusion, each RIT of the proposal is able to utilize at least one frequency band identified for
IMT in the ITU Radio Regulations [i.13].
5.2.4.2.2 Higher Frequency range/band(s)
Is the proposal able to utilize the higher frequency range/band(s) above 24,25 GHz?
 YES /  NO
Specify in which band(s) the candidate RIT or candidate SRIT can be deployed.
See note.
According to information provided in Contribution 5D/1299 [i.14] (characteristic template under
clauses 5.2.3.2.8.3 and 5.2.4.1.1 of self-evaluation), it is envisioned by the proponent that frequency
ranges above 24,25 GHz are supported. According to published ETSI TS 103 636-2 [i.7], the
support of frequency ranges above 24,25 GHz is not yet implemented.
Therefore, the component RIT DECT-2020 NR is currently not utilizing the higher frequency
range/band(s) above 24,25 GHz.
The component RIT 3GPP 5G NR is concluded by Contribution 5D/1299 [i.14] to be able to utilize
the higher frequency range/band(s) above 24,25 GHz.
In conclusion, the candidate SRIT fulfils the condition that at least one of the component RITs needs
to fulfil this requirement.
NOTE: In the case of the candidate SRIT, at least one of the component RITs need to fulfil this requirement.

6 Evaluation ETSI/DECT Forum SRIT
6.1 Introduction
The ETSI EG evaluated the DECT-2020 NR component RIT in the submission in Contribution IMT-2020/17
(Rev. 1) [i.15].
3GPP 5G NR component RIT of the proposal was reviewed by other IEGs and already concluded by Contribution
5D/1299 [i.14] to fulfil the requirements.
6.2 Parameters evaluated via Inspection
6.2.1 Bandwidth
6.2.1.1 Conclusion
Support of at least 100 MHz bandwidth is confirmed with a value of 221,184 MHz.
Support of up to 1 GHz bandwidth is possible by utilizing multiple carriers in parallel. Nevertheless, the support of this
requirement is relevant only for higher frequency bands.
Support of multiple different bandwidth values is confirmed with a range from 1,728 MHz to 221,184 MHz.
6.2.1.2 Verification
According to information provided in Contribution 5D/1299 [i.14] (characteristic template under clauses 5.2.3.2.8.2 and
5.2.4.1.1 of self-evaluation) the DECT-2020 NR supports scalable bandwidth via:
• Scaling FFT Size (64, 128, 256, 512, 1 024); and
• Scaling sub-carrier spacing (27 kHz, 54 kHz, 108 kHz, 216 kHz, 432 kHz).
Further transmission via multiple carriers is supported.
From this, the minimum bandwidth for a single RF carrier is found to be 64 × 27 kHz = 1,728 MHz.
From this, the maximum bandwidth for a single RF carrier is found to be 1 024 × 432 kHz = 442,368 MHz.
Considering DECT-2020 NR release 1 specification ETSI TS 103 636-3 [i.8], Table 4.3-1 the support of sub-carrier
spacings up to 216 kHz is specified. Therefore, the maximum bandwidth for a single RF carrier is currently found to be
specified up to 1 024 × 216 kHz = 221,184 MHz.
6.2.2 Spectrum
6.2.2.1 Conclusion
The ETSI EG concludes that the spectrum requirements are met by the SRIT in submission IMT-2020/17 (Rev. 1)
[i.15].
6.2.2.2 Verification
Each component RIT is found to be able to utilize at least one frequency band identified for IMT in the ITU Radio
Regulations [i.13] (for the list of frequency bands of DECT-2020 NR see clause 5.1.2 of the present document).
The SRIT can utilize the higher frequency range/band(s) above 24,25 GHz at least with the 3GPP NR component.
ETSI
17 ETSI TR 103 810 V1.1.1 (2021-11)
6.2.3 Services
6.2.3.1 Conclusion
The ETSI EG concluded that DECT-2020 NR is able to support URLLC and mMTC services.
The candidate RIT 3GPP 5G NR is identical to the submission by 3GPP, which was concluded by Contribution
5D/1299 [i.14] to support eMBB, URLLC, and mMTC services.
In conclusion, the proposal is able to support a range of services across different usage scenarios.
Each component RIT of the proposed SRIT is able to support at least two different usage scenarios.
6.2.3.2 Verification
The support of a wide range of services is verified by inspection of the candidate RITs/SRITs ability to meet the minimum
technical performance requirements for various usage scenarios and their associated test environments.
The proposed SRIT consists of:
• "DECT-2020 NR" component RIT; and
• "3GPP 5G NR" component RIT.
Each component RIT of an SRIT needs to support at least two different usage scenarios.
The component RIT 3GPP 5G NR is identical to the submission by 3GPP, which was concluded by ITU-R WP 5D to
support eMBB, URLLC, and mMTC.
The proposed RIT DECT-2020 NR supports according to the submission in Contribution IMT-2020/17 (Rev. 1) [i.15]
the usage scenarios URLLC and mMTC.
Considering the evaluation results in clause 6.4.1 of the present document, ETSI EG concluded that DECT-2020 NR is
able to support mMTC services.
Considering the evaluation results given in clause 6.4.2 of the present document, ETSI EG concluded that DECT-2020
NR is able to support URLLC services.
6.3 Parameters evaluated via Analysis
6.3.1 User Plane Latency
6.3.1.1 Conclusion
The ETSI EG concluded that DECT-2020 NR is able to support user plane latencies below 1 ms as defined in Report
ITU-R M.2410-0 [i.1], section 4.7.1 in several configurations.
The user plane latency is in the range of 0,11 ms to 0,96 ms for configurations satisfying the requirement.
6.3.1.2 Verification
In reference to Contribution 5D/1299 [i.14], characteristics template:
• 5.2.3.2.2.1: multiple access scheme FDMA/TDMA
• 5.2.3.2.7.1: Overall numerology for 27 kHz sub-carrier-spacing
• 5.2.3.2.8.2: Channel bandwidth scalability (see also 12.2.1.1 of this document)
• 5.2.3.2.12.2: Half-slot and frame-less mode
ETSI
18 ETSI TR 103 810 V1.1.1 (2021-11)
• 5.2.3.2.20.5: Optional use of HARQ with soft-combining
Further, the Technical Specifications of DECT-2020 NR in ETSI TS 103 636-3 (PHY) [i.8] and ETSI TS 103 636-4
(MAC) [i.9] are considered.
The transmission configurations as given in Table 2 are employed for evaluation, which enables transmission of more
