Foreword
This Technical Specification has been produced by the 3rd Generation Partnership Project (3GPP).
The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.
In the present document, modal verbs have the following meanings:
shall indicates a mandatory requirement to do something
shall not indicates an interdiction (prohibition) to do something
The constructions "shall" and "shall not" are confined to the context of normative provisions, and do not appear in
Technical Reports.
The constructions "must" and "must not" are not used as substitutes for "shall" and "shall not". Their use is avoided
insofar as possible, and they are not used in a normative context except in a direct citation from an external, referenced,
non-3GPP document, or so as to maintain continuity of style when extending or modifying the provisions of such a
referenced document.
should indicates a recommendation to do something
should not indicates a recommendation not to do something
may indicates permission to do something
need not indicates permission not to do something
The construction "may not" is ambiguous and is not used in normative elements. The unambiguous constructions
"might not" or "shall not" are used instead, depending upon the meaning intended.
can indicates that something is possible
cannot indicates that something is impossible
The constructions "can" and "cannot" are not substitutes for "may" and "need not".
will indicates that something is certain or expected to happen as a result of action taken by an agency
the behaviour of which is outside the scope of the present document
will not indicates that something is certain or expected not to happen as a result of action taken by an
agency the behaviour of which is outside the scope of the present document
might indicates a likelihood that something will happen as a result of action taken by some agency the
behaviour of which is outside the scope of the present document

might not indicates a likelihood that something will not happen as a result of action taken by some agency
the behaviour of which is outside the scope of the present document
In addition:
is (or any other verb in the indicative mood) indicates a statement of fact
is not (or any other negative verb in the indicative mood) indicates a statement of fact
The constructions "is" and "is not" do not indicate requirements.

4 General
4.1 Relationship between minimum requirements and test
requirements
The Minimum Requirements given in this specification make no allowance for measurement uncertainty. The test
specification in RAN5 will define test tolerances for FR1 and FR2 MIMO OTA. The test tolerances are used to relax
the minimum requirements in this specification to create test requirements.
4.2 Applicability of minimum requirements

The MIMO OTA minimum requirements apply only to the primary mechanical mode of UE which is declared by the
manufacturer if the UE can support multiple mechanical modes.
The minimum requirements apply only to the UE under normal environmental conditions specified in Annex F.
5 Frequency bands
5.1 General
NR MIMO OTA Requirements are defined separately for different frequency ranges (FR). The frequency ranges in
which NR can operate according to this version of the specification are identified as described in Table 5.1-1.
Table 5.1-1: Definition of frequency ranges
Frequency range Corresponding frequency range
designation
FR1 410 MHz – 7125 MHz
FR2 24250 MHz – 52600 MHz

The present specification covers both FR1 and FR2 operating bands. For FR2, only FR2-1 bands are applicable.
5.2 Operating bands
NR is designed to operate in FR1 operating bands defined in TS 38.101-1 [3] and FR2 operating bands defined in TS
38.101-2 [4]. NSA band combinations are defined in TS 38.101-3 [5]. E-UTRA is designed to operate in operating
bands defined in TS 36.101 [6].
6 FR1 MIMO OTA requirements
6.1 General
6.1.1 Definition of MIMO throughput
The MIMO throughput is defined here as the time-averaged number of correctly received transport blocks in a
communication system running an application, where a Transport Block is defined in the reference measurement

channel. From OTA perspective, this is also called MIMO OTA throughput. It will be used as the baseline figure of
merit for FR1 and FR2 MIMO OTA testing.
The MIMO OTA throughput is measured at the top of physical layer of NR system under the use of FRC, the SS
transmit fixed-size payload bits to the DUT. The DUT signals back either ACK or NACK to the SS. The SS then
records the following:
- Number of ACKs,
- Number of NACKs, and
- Number of DTX slots
Hence the MIMO (OTA) throughput can be calculated as
Transmitted TBS × Num of ACKs

MIMO (OTA) Throughput =
MeasurementTime
Where Transmitted TBS is the Transport Block Size transmitted by the SS, which is fixed for an FRC during the
measurement period. MeasurementTime is the total co
